How and from what you can make real asphalt yourself. Do-it-yourself technologies and recipes for making high-quality asphalt

Many owners of suburban real estate admit the idea of ​​making asphalt with their own hands. However, in order to obtain a reliable road surface, it is very important to take into account performance characteristics site, as well as comply with all requirements technological process to get a quality canvas.

What is asphalt

Asphalt, or more precisely asphalt concrete, is a multi-component material that includes the following ingredients:

• Sand. It is necessary as a binder, and in some cases (when cement is added) it is able to increase mechanical strength roadbed.
• Rubble. It is a reinforcing component and does not allow ready-made layers to crack under the influence of significant loads.
• bituminous resin. Acts as a paste for bonding all components, and also provides additional waterproofing of the web.

Sometimes, polymeric additives are introduced into asphalt concrete, which can provide its high performance, but due to the high cost, they are used extremely rarely.

Preparatory part

In order for do-it-yourself asphalt to fully fulfill its functions, it is very important to follow the manufacturing technology of the material and adhere to the laying recommendations. The first step in this direction, of course, is preparation.

So, what we need is to prepare all the necessary components (sand, crushed stone, bituminous resin); to provide the possibility of "cooking" the composition: a large metal container and a heat source will be required (usually a fire is used). And also stock up on a large amount of water as a means of protection (to limit combustion).

Now about everything in order.

The first thing to take care of is to make a container for mixing the components, because you agree to use a traditional concrete mixer for asphalt production - an unjustified luxury.

As a container, it is quite justified to use a metal barrel (150 - 200 liters), to the bottom of which it is necessary to weld an L-shaped handle and make it possible to rotate the device around its own axis. By the way, you can read about how to make a concrete mixer yourself.

In parallel with this, building bitumen should be melted in a separate container (usually a large bucket is used). When doing this work, you need to be very scrupulous and take into account the possibility of ignition of the resin (sand and water should be nearby if extinguishing is necessary).

The next step is mixing bitumen with sand and gravel, for which the heated resin is simply poured into a barrel with bulk substances and thoroughly mixed (by turning). However, when performing this part of the work, it is necessary to take into account the fact that the barrel and the components in it must be well heated. Indeed, otherwise the material will quickly cool down, and it will not be possible to perform its high-quality mixing.

A good indicator of the readiness of the solution is water. After all, if you pour it into a barrel with bitumen, sand and gravel hot water, and then warming up the whole substance, you can achieve good performance. Well, the complete evaporation of the liquid from the barrel will indicate the readiness of the asphalt.

Material laying process

Of course, pouring self-made asphalt concrete on an unprepared base is not justified. In view of this, before laying the material, it is desirable to clean the place of work from debris, dust, or even blow it with air.

After that, the heated asphalt is poured onto the required area and it is compacted using a manual roller or rammer. It should be noted that in order to minimize the adhesion of the material to the tool, it is desirable to moisten the latter with water.

After hardening, the asphalt is ready for use.

Features of laying cold asphalt

Recently, more and more often, owners of suburban real estate use cold-type asphalt for the arrangement of adjacent territories. This product is sold in a ready-to-use form and is a mixture of flowing bitumen, polymer fillers and modifiers (provide the hardening process). Moreover, it is precisely such a product that can be easily laid at low temperatures, which cannot be done with traditional material. Whereas the performance characteristics and price parameters of this material are much higher than those of conventional asphalt.

The method of laying cold asphalt is practically no different from the above described option and boils down to the fact that the finished material is poured out in the required place and rammed with the help of rammers or car wheels.

New asphalt from old

Recently, more and more often after auto repair pavement old (cut) asphalt concrete remains specialized services. It turns out that it can also be used to make a high-quality road surface. And all that is needed for this is to break the pieces of old asphalt into small fractions and lay in the required place with a layer of about 10 cm. In the final, the stony base should be rolled with a road roller. It should be noted that doing said works should be carried out in warm weather in order for the resin present in the cut asphalt to melt a little and fill all the voids.

One of the most common recycled materials is crushed asphalt, also known as asphalt granulate, which is used in a wide range of construction and repair jobs.

This material is obtained by grinding the old asphalt pavement, removed during the replacement or repair of the roadway, by cold milling. Thus, asphalt crumb consists of particles of bitumen and small gravel from three to five millimeters in diameter, in addition, it may contain traces of sand or other elements.

The use of asphalt

Due to the inexpensive price, ease of operation, and the fact that the crumb as a product obtained by processing causes relatively less harm to the environment, the range of its application is extremely wide and includes almost all spheres of human economic activity:

Due to the wide use of this material, as well as the presence of many other options on the market, consumers, in an attempt to find the most suitable option for themselves, often ask how much a cube of asphalt chips costs. Below, in the thesis form, the main reference characteristics of this material are given, including answers to such questions as how much 1 cube of asphalt crumb weighs and how many cubes fit in a KAMAZ or dump truck.

• The average price of asphalt chips in Moscow is $12-14, in the regions it starts from $10;
• 1 cube of asphalt chips can weigh from 1500 to 1900 kilograms, depending on its composition;
• Accordingly, about 12 cubic meters will fit in the body of an average KAMAZ;

The crumb consumption per m 2 with a layer thickness of 20 centimeters is approximately 400-600 kilograms.

Laying technology

1. First of all, the base for the asphalt crumb is prepared. The area is leveled, large debris is removed: cobblestones and scrap metal. This item may well be skipped if the condition of the terrain is acceptable for the purpose.
2. The surface is variably primed using a bitumen emulsion of asphalt chips for better adhesion in the future. Its consumption is about one liter per sq.m.;
3. Laying out crumbs on the surface, compacting the laid out layer. This can be done both with specialized equipment and independently. It is worth remembering that the compaction coefficient of asphalt chips, depending on the composition, reaches a value of 2 units, which means that when rolling, the thickness can decrease up to two times and be sure to include this factor in the calculations!
4. Impregnation of bitumen emulsion of asphalt crumb. This will further strengthen it and increase its service life. Consumption is about 0.5 liters per m 2.

Do-it-yourself asphalt crumb laying is not too different from the technology described above. The only difference is that you will have to lay it out yourself with the help of shovels, and roll it with cars. Difficulties may arise with how to melt asphalt chips: without the use of technology, this is not only laborious, but also flammable. You can melt the crumb over an open fire in a metal container of sufficient size. Be sure to have a fire extinguisher with you to extinguish a possible fire!

Pros and cons of using asphalt chips

To begin with, let's mention the environmental aspect of the use of asphalt chips. Many people, from among those who will ennoble their summer cottage, having children and animals in the family, are interested in whether asphalt chips are harmful. Despite the fact that it contains bitumen - a product of oil refining, which, accordingly, causes more harm to the environment than good, the use of crumbs in the economy is more environmentally friendly than in the case of asphalt of the same volumes.

According to the documentation, asphalt crumb has a hazard class 4, on a par with household waste, such as old clothes and shoes.

1. A wide range of applications, covering most of the areas of human economic activity;
2. Affordable price, which favorably distinguishes asphalt crumb against the background of crushed stone or gravel and, due to similar properties, has recommended the crumb as a suitable replacement for them;
3. Long service life when used in suitable conditions for this: minor roads and paths of short length and sports complexes;
4. Ease of installation. To do this, it is not necessary to prepare the surface in advance, and the rolling of asphalt chips does not imply the mandatory participation of special equipment; in order to save money, it can be done with the help of passing cars;
5. High resistance to adverse weather conditions.

Disadvantages of asphalt crumb, like any other material, exist:

1. More harmful effect on environment compared to gravel or sand;
2. The need for periodic updating of the canvas.

However, all the shortcomings are fully covered by its numerous positive qualities.

Alternatives

In addition, consumers often ask the question: which is better, asphalt chips or crushed stone? There is no unequivocal answer to it, since these materials, including sand and broken bricks and concrete, as a rule, perform the same functions. But the price of crumbs is lower, and crushed stone has a less harmful effect due to the absence of bitumen in the composition. So it is necessary to make a choice based on circumstances and personal preferences.

Summing up

Thus, asphalt crumb will become for you ideal option if you value simplicity and convenience in installation and prefer to spend extra money on yourself and your loved ones, rather than on building materials. For a parking lot or driveway, sports field or garage floor, this material will meet your every need!

We will also consider methods, proportions and technologies. self-manufacturing asphalt from bitumen, sand, crushed stone and old asphalt. Learn how to properly lay homemade asphalt on personal plot

First of all, let's consider what classic industrial asphalt is made of?
Asphalt concrete is produced from crushed stone, sand (for better filling of small holes that crushed stone cannot fill), mineral filler (sandstone, limestone and others are used for better enveloping) and bitumen (a kind of binding material, "glue"). Gravel may also be included in the recipe. Each component in the manufacture of asphalt concrete is necessary for better compaction of the asphalt pavement.

Types of asphalt

Asphalt concrete, depending on its components, can be sandy (sand + bitumen), crushed stone (crushed stone + sand + bitumen + mineral powder) and gravel (gravel + crushed stone + bitumen + mineral powder). Only the right proportion of these components can result in quality asphalt.

Asphalt paving can also be hot and warm. But the difference in degrees is not that big. During hot laying, the temperature of the asphalt mix ranges from 130 to 170°C, while during cold laying, it should not be lower than 80°C. Cold laying of asphalt concrete is used for local (patching) repair

Asphalt production in the factory

The production of asphalt concrete takes place in several stages. First, the quality of the source material (crushed stone, bitumen and mineral additives). After that, the process of processing inert materials begins. As already mentioned, the production of a standard asphalt mixture is made from crushed stone, sand, mineral material and bitumen.

To begin with, the sand is sifted, and the crushed stone is divided into fractions of various sizes (from 5 to 20 mm) using a screen. Further, in accordance with the recipe, they enter a special drum for drying. A high temperature is maintained inside the drum in order to completely remove water from the mixture during the manufacturing process, as it degrades the strength of the future asphalt concrete.In addition to the fact that sand and gravel (it is possible to add screenings) are dried in the bunker at a temperature of about one hundred and sixty degrees, they are mixed with each other. Simultaneously with the drying of solid materials, the bitumen in the tanks is heated up to the same one hundred and sixty degrees. During the heating process, it is very important to observe desired temperature, the binder must not be too liquid or too hard.

At the next stage of production after heating, all components of asphalt concrete (crushed stone, sand, mineral additives and bitumen) are mixed. The material is mixed with special blades in a separate hopper. Mixing is necessary for better enveloping, adhesion of bitumen with grains of crushed stone and sand, mineral additives also improve the quality of asphalt concrete (filling unnecessary voids into which water can enter and destroy the road). In some factories, the asphalt mixture is passed through a series of sieves during mixing, thus, the asphalt is divided into the required number of portions with a uniform distribution of the asphalt concrete components.

For asphalt, it is very important to keep the proportion during manufacture, since the quality of the future road depends on it. After all, asphalt can melt in summer, and crack in winter precisely because of the wrong selection of components and laying temperature.

After thorough mixing, the hot asphalt goes into a storage bin (which is also kept at a high temperature).

Recipe for making asphalt at home:

Take the old compacted asphalt, crumble it into pieces 5x5x5cm in size. Add bitumen crushed with the same pieces 5x5x5cm. Proportions 3:1.
Put a barrel or a deep trough on a fire, pour bitumen into it first, then asphalt and cook so that there is more fire from the fire, not coal. You can also add used oil there, or old roofing material.

And cook, stir occasionally with a wooden stick until the whole mass becomes liquid. moreover, it is better not to take out the stick, you must constantly keep one end in the barrel. The finished asphalt becomes liquid and is divided into a more liquid fraction, which floats to the top, and all the pebbles sink down.

It is necessary to pour asphalt from a barrel into a bucket as follows: tilt it, the upper edge rests on the substituted bucket, and begin to scoop out the contents, raking heavy fractions from the bottom with a shovel.
To pour asphalt into the next bucket, you must first mix the entire mass in the barrel, otherwise the entire light fraction will pour out first. And it just contains a lot of bitumen, but it has few mineral additives.
Keep this in mind when pouring, otherwise you will not achieve the desired effect.

While you are pouring, keep the barrel of asphalt all the time on the fire, it is better to put it upside down on the coals so that the mass is very hot all the time. As asphalt was poured into a bucket, be sure to count the molten asphalt from the walls of the barrel, then it will not cool down and accumulate on the wall.

Please note that old asphalt will be reduced by more than 2 times. And if you have a standard 200-liter barrel, then you need to fill it halfway, and then it will not be so difficult to mix and tilt it. Even such a barrel will cook for 4-6 hours. It will need 15 buckets: 12 - asphalt, 3 - bitumen.

When you pour asphalt, level it wooden board and immediately throw small gravel on top, before everything has thickened yet. If there is some asphalt left in the bucket, next time you can put it on a fire next to the barrel and melt it.
And after cooking, be sure to clean the bottom of the barrel from slag, which burns to the walls and to the bottom.

First pour bitumen into the barrel, then asphalt. Cook in such a way that there is more flame from the fire, and not coals, you can use waste oil, old roofing material from the roof, especially if rotten wood is used as firewood.
When it becomes more or less liquid, periodically stir with a wooden stick for uniform heating, keep the end of the stick in the barrel where the asphalt is being cooked, without removing it.
It is convenient to cook on a slope, placing bricks under the barrel, one brick from the side of the hill, from the side of the slope - two supports, two bricks on top of each other.
When welded, the molten asphalt becomes liquid, easily mixed with a wooden stick or a shovel, is divided into a more liquid fraction at the top and with pebbles at the bottom.
To pour asphalt into a bucket, a pair of bricks is taken out from the side of the slope and placed in two rows on the sides of the expected slope of the barrel so that the barrel does not roll to the sides.
Then the barrel is tilted and placed along the slope, resting its upper edge on a substituted bucket, and the contents are poured into the bucket, helping with a shovel, scooping up the heavier fractions from the bottom.

Before pouring the asphalt in the barrel is mixed every time. Anyway, the lighter fraction is poured first, containing more bitumen and less mineral additives, which must be taken into account when pouring.
Having filled the bucket, hold it so that it does not tip over the slope, and return the barrel to an upright position so that it lies on the bottom of the coals from the fire and the contents continue to heat up while the pouring process takes place. After returning the barrel
in a vertical position wooden plank clean the melted asphalt from the wall to the bottom so that it does not cool on the wall.
You can dig a hole for the bucket and fill it with bricks, in this case, at the beginning of pouring, the bucket is placed on the bricks on the same level with the ground, and during subsequent pouring, the bricks are gradually removed from the hole so that the bucket sinks deeper
and the barrel, leaning on the edge of the bucket, each time leaned lower and lower, until the bucket sank to its full height and the barrel fell completely to the ground.
If, from the beginning of cooking, a bucket filled with asphalt and bitumen is placed next to the barrel on the fire, then two more buckets of cast asphalt can be additionally welded while the asphalt is being cooked in the barrel.

Old asphalt is more than doubled. A 200-liter barrel should be filled to no more than half (15 six-liter buckets - 12 asphalt and 3 bitumen), otherwise it is difficult to mix and turn a full barrel. Such a barrel is brewed from 4 to 6 hours.
When pouring, the asphalt is leveled with a wooden stick or board, and fine gravel is immediately thrown onto the flooded area while the asphalt is still liquid. Asphalt, which thickened in the bucket and remained in it, is left for the next cooking to be put in the same bucket next to the barrel on fire and melted.
Molded asphalt melts much more easily than compressed asphalt. The barrel and bucket must be cleaned every time after cooking by beating off the slag sticking to the walls and bottom, otherwise the cooking time next time increases very significantly.Speaking about asphalt, I immediately want to say that this building material has more disadvantages than advantages in relation to summer cottage. Asphalt pavement has only a few main advantages - low cost, high strength, simple technology creation and versatility. Often asphalt is chosen only because it has the lowest price compared to paving materials for garden paths such as paving slabs, paving stones, decking, natural stone etc.

The disadvantages of asphalt are very significant factors that affect not only landscape design garden plot. Among the most significant shortcomings are:

1. In hot weather, asphalt evaporates and exposes the human body to harmful substances. In addition to this, he bad smell will not allow you to have a rich rest in the garden, which is what we need.

2. Asphalt coating practically does not have a decorative ability, therefore, it will not only not be suitable for decorating a site, but, on the contrary, will worsen the situation. Asphalt paths practically do not fit into garden styles, which is also very bad. The only exception is colored asphalt, to which various pigments are added, so that the coating can be not only the usual gray color, but also green, pink, blue, etc.

3. With poor-quality laying, asphalt quickly collapses into winter period: water enters the cracks, freezes, and when it freezes, it destroys the coating.

4. During the heat, the asphalt melts.

As you can see, the disadvantages of asphalt pavement are more significant than the advantages, but despite this, asphalt paths are recommended to be built at the functional nodes of the garden: for example, between the garage and the utility block. It is strictly forbidden to build asphalt paths near recreation areas, because of the harmfulness of asphalt.
How to lay asphalt with your own hands?

In order to put asphalt in the country with your own hands, you need to carefully prepare the area, know the technology of laying asphalt and have at least a home-made manual roller for asphalting.

You should immediately draw your attention to the fact that it is very difficult to make asphalt on your own, because. it is necessary to heat up the bitumen, mix it with crushed stone and additives and know correct proportions. Since asphalt is not expensive, it is best to order a ready mix from a road repair company. In this case, you will not lose a lot of money, for that the asphalt will be brought to you hot directly to the place of laying, all that remains is to quickly level it, compact it and roll it.

Do-it-yourself preparation of the area for asphalting

First of all, we mark the boundaries of the future asphalt track. At this place, it is necessary to remove a layer of soil (at least 30 cm, it all depends on the purpose of the path) and make sure that tree roots do not pass near the future path, otherwise they will soon begin to destroy the asphalt. If there are roots, then we cut them down with an ax. After that, along the entire perimeter of the track, we install borders, which will be the borders.

The role of the curb is not only to prevent the spread of asphalt, but also a decorative function. To install the curbs, we dig a small, even trench and plant them on cement mortar into this trench. To create an even border, we stretch the rope from the beginning to the end of the sides of the track and navigate along this rope. As a border, you can use bricks that are laid not only on the side faces, but also on the side.

Next, we proceed to create a pillow under the asphalt. We carefully tamp the bottom of the trench for the path, fill it with the first layer - crushed stone (10-15 cm thick, large fraction) and again tamp. On this layer we fall asleep another layer of crushed stone, but only of a smaller fraction, the layer thickness is not more than 10 cm. Well, last layer- sandy, about 5-10 cm. As soon as the pillow is created, fill it with water and, using a roller, carefully roll it.

In order to prevent water from collecting on an asphalt path, make a small drain in advance: build the path at an inclination of 1-2 degrees and circle it with drainage that directs the flow of water into the soil.

Self-laying new asphalt

As we said earlier, it is more expedient to order asphalt at the factory. After the asphalt is delivered to your site, you must immediately proceed to laying it, because the solution quickly hardens.

First of all, we spread the asphalt with a shovel over the entire area of ​​\u200b\u200bthe track, making it evenly filled. Further, using a mop-engine, we level the asphalt along the entire path, while throwing asphalt into the pits, and leveling the bumps. It should be noted that the minimum thickness of the asphalt pavement must be at least 5 cm to ensure the strength of the garden path, so this requirement must be observed.

As mentioned earlier, asphalt hardens quickly, so it’s better to invite a few helpers to create a path so that the process goes faster.

As soon as part of the track is planned out, we take a hand roller and begin to roll this segment, while the rest plan the track further.

Mandatory requirement: before rolling the track, lubricate the skating rink with diesel fuel so that the asphalt does not stick to it and the track is perfectly flat. You can also lubricate the shovels with diesel fuel, so that it would be easier to throw asphalt onto the track.

When working with the roller, it is necessary to move slowly while making only rectilinear movements (reverse movements are prohibited). During rolling, seams will form at the junctions between the lines, in order to remove them, it is necessary to roll across the seams.

Never leave the roller on the track after work.

For high-quality rolling, the roller should protrude beyond the border of the track by at least 10 cm.

If the weight of the roller is not enough for a good rolling of the track, then you can ask one of the assistants to stand on the frame of the roller, then the weight will increase.

Laying asphalt on the old pavement on the plot

If you decide to lay asphalt not on the soil, but on the old asphalt surface or concrete screeds, then the terrain preparation process will change. Instead of a pillow of crushed stone and sand, you just need to repair the old coating. To do this, you need to rid the surface of dirt and various debris, if there are small cracks, they must be expanded by hand, so that in the future they would be tightly clogged with asphalt.

After that, it is necessary to pour molten bitumen around the entire perimeter of the future garden path and, using a mop-engine, smear the bitumen into strips of 50 cm (not less). Along the entire length of the path, it is necessary to make transverse bituminous strips in increments of half a meter, and then we create an asphalt path with our own hands using the technology indicated above.

How to repair an asphalt path yourself?

Even if you have laid the asphalt with your own hands with high quality, the path will still begin to collapse sooner or later. The most common damaging factors are:

Asphalt began to melt in hot weather

Water got into the cracks in winter and when it thawed, it destroyed the coating

Heavy equipment, for which this track is not designed, drove onto an asphalt path

In order to repair the asphalt pavement with your own hands, it is recommended to use cold asphalt, which can be laid even at low temperatures (minus).
How to cover broken asphalt?

If the paved path has completely collapsed and is not suitable for repair, then this situation must be corrected. There are two ways to fix a broken asphalt path:

1. Remove asphalt and re-pave

2. Lay on top of the asphalt paving slabs or pour concrete screed

As for the first method, all construction companies engaged in road repair must remove the broken asphalt, re-create a cushion of crushed stone and sand, and roll out a new asphalt surface. For an inconspicuous garden path, this process will be difficult and not economically viable.

It would be more expedient to fill a layer of sand (at least 5 cm) on top of the asphalt, fill it with water and start paving paving slabs.

In order to save money, today they often resort to the restoration of asphalt that has already been in use. Let's take a closer look at how to use old asphalt and what it takes.

The secondary use of asphalt is possible only after regeneration, which is carried out at the plant. But this process is simple and quite allows you to do all the work yourself.

Having carefully tamped the soil in the place of future asphalt laying, we equip a pillow of sand and gravel, water it and re-compact the layer. This completes the preparation of the foundation - now you need to acquire the source material that remains with you after the dismantling of the old coating, or simply buy old asphalt. You will also need a few kilograms of bitumen and physical strength.

In order to melt the old asphalt, we load it into a metal container along with the purchased bitumen and heat it up. To do this, simply place the container over the fire. We constantly stir the composition until it melts to a homogeneous mass, after which we add a little more crushed stone and sand so that the mixture has a crumbly consistency. The recycled asphalt can then be laid on top of the previously formed base. To avoid sticking of the composition to the surface of the stacker, it is possible to treat the sealing surface of the device with old oil mining.

That, in fact, is all you need to know about how to use old asphalt at home.

Recycling of asphalt at the plant, as mentioned above, is carried out by the regeneration method. In this case, while mixing the molten composition of the old asphalt, new mineral fillers and plasticizers are sometimes added to it, in addition to standard bitumen.

Recycling of asphalt to improve the efficiency of recovery plants, it is better to do it after grinding. Also, this method significantly increases the degree of accuracy of the batch recipe. But, in this case, it is necessary to additionally deal with the sticking of asphalt material on the working elements of crushers. The solution to this problem was thermal crushing in steam plants. In such aggregates during crushing, the material is heated up to 80°C. But this is abroad, and in domestic production, in order to regenerate old asphalt, in the standard version, conventional installations are used to mix such compositions. Also, additional equipment for the storage, transportation and dosage of asphalt concrete mix is ​​used.

The main components of this material are crushed stone, ordinary river sand, bituminous resin, as well as polymer materials for laying on the surface. The last component is not always used, as it is expensive, they are mainly used in the construction of motorways and highways. Despite the fact that all the components can be found in the shed, it will be a little difficult to make a paving in the country. You need to seriously prepare for this process.

We need a container for mixing the “ingredients”, a hearth of fire (can be a fire) for 6-8 hours continuously, about 100 liters of water to cool the suspension, as well as one of the pastes so that everything is kept in a pile. Resin or bitumen (preferably) can play its role. Consider step by step instructions for manufacturing.

Step 1 We prepare the container.

The first step is to make a prototype of a concrete mixer, since it would be irrational to “kill” an expensive and useful item. For our purposes, a metal barrel from oil or diesel fuel, in which a branded product is sold, is suitable. If you don’t have one, you can buy it for a penny (or borrow it free of charge) from any farmer or from the company itself, which pours oil into retail containers. They are often thrown into scrap metal as a waste product. Close the lid, drill holes in the center from the bottom. We pass a metal rod (pipe, corner, square, etc.) and scald inverter welding so that there are no leaks anywhere. We weld an L-shaped twig to one of the edges, it turns out a “spit”.

Step 2 We mix the components.

We pour crushed stone into our “concrete mixer”, add a little sand (2: 1) there, mix everything thoroughly. You can’t collect wet building materials - they will immediately stick together, and it will be very difficult to pick them off the metal walls.

Step 3 We heat bitumen and polymer additives.

In a separate container (it is best to take a 15-liter bucket), we need to heat the bitumen to a boil, for better elasticity, you can add shampoo to it. It then burns out, but it will be much more convenient to interfere. We also add polymers and plasticizers there.

Step 4 We mix everything together.

You don’t need a lot of imagination here, just take and add boiling bitumen to a preheated barrel with crushed stone and sand. Important: you can not mix if the barrel and all the components are not warmed up - the bitumen will quickly cool down and it will be unrealistic to stir. For convenience, you can first add 50 liters of water to a barrel and bring to a boil. After that, pour in the bitumen and stir until the water evaporates.

The boiling point of water is 100 degrees, exactly what we need for bitumen to make it fluid and sticky. Remember that you can not overheat this material - it ignites at a temperature of 170 degrees, so watch the water. Just finished - pour it out!

Step 5 We fill in the holes.

The area into which you will pour the asphalt must be thoroughly cleaned, preferably blown out with a compressor. After pouring the hot mixture, you need to take a roller or any other tool (rammer) and compact the material. Be sure to moisten the metal of the tool with water so that it does not stick to the bitumen during tamping.

If you follow the instructions, then making asphalt at home will be safe, fast and even very interesting!

What is cold asphalt and what is its feature

Quite recently, a rather interesting product, polymeric asphalt, came to the territory of Russia. Its peculiarity is that it can be laid absolutely at any temperature. Tests showed excellent viscosity and stickiness even at -20C, which makes it possible to repair roads or make an entrance to the cottage even in winter.

It includes fluid bitumen grade SG or MG 70/130, characterized by increased viscosity. It also contains special plasticizers and modifiers that act similarly to " cold welding". Due to this, it is possible even negative temperature get great results. The paths will have increased strength and will last much longer than conventional asphalt. The technology has been introduced for more than 5 years in Russia, and now anyone can buy such material.

It makes no sense to look for a method on how to make asphalt with your own hands, since cold technology implies a high-tech manufacturing process under pressure and is not available at home. Its cost is much higher than the usual road surface, so it is rarely used in industry. But each summer resident can buy the right amount to make paths in the garden or a small driveway for a car. You can buy in a regular store. Installation does not require special knowledge: just pour the mixture into the right place and compact it in any convenient way, even with car tires.

How to make new asphalt from old pavement

Another very popular method to ennoble a site without much capital investment is to use the old pavement as the main raw material for the manufacture of a new one. To do this, we need about 100 kg of old coating, which is thrown away during the repair of the highway, fresh bitumen, 10 kg of resin for elasticity and a concrete hardener. Consider step by step what needs to be done.

Asphalt is often used to improve the local area. For the manufacture of asphalt mass, use the advice and instructions of specialists, which are given in this article. They will help to perform all operations with high quality and get reliable construction material for paving the road.

Components of the asphalt mass and tools for their preparation

Depending on the technology that will be used to produce the asphalt mix, you will need the following set source materials and tools:

• natural mountain asphalt;
• sand;
• bitumen;
• crushed stone;
• water;
• Bulgarian;
• drill;
• metallic profile;
• mixing container.

Hot asphalt production

Careful preparation and study of the process technology will help to establish the production of hot asphalt for the needs of a private household. The composition of the asphalt mass includes bituminous resin, fine gravel, sand and artificial polymers. For their mixing and subsequent heat treatment, a refractory container is used. Fuel is prepared to maintain the required temperature based on 8 hours of burning. 100 liters of water will be needed to cool the mixture.

Method of making hot asphalt:

1. Choose a working capacity.
2. We mix dry sand and small gravel.
3. We heat the bituminous resin and polymers to the state of a fluid mass.
4. We introduce plasticizers into a heated container with sand and gravel.
5. Stir until a homogeneous suspension is formed.
6. We use asphalt paving.

Benefits of cold asphalt

Cold asphalt is a modern building material that is used to quick repair and road construction. The high functionality of the suspension is determined by the SG bitumen. The plasticizer of this brand is characterized by high viscosity and retains plasticity at low temperatures.

The production of cold asphalt is a complex high-tech process, which cannot be recreated in the conditions of subsidiary farming. But, due to the wide distribution of the material in the construction market, summer residents can purchase it ready-made. A mass of cold asphalt is laid on the site and compacted using improvised tools.

Asphalt from the old roadway

Pieces of destroyed pavement can be used as raw materials for the production of asphalt mass. Thanks to this technique, you can easily ennoble the site without the need for large investments.

Pavement reuse technology:

1. Grind pieces of canvas to a fraction of 0.4 cm in size.
2. We add sand, water and bring the mixture to a temperature of 100 ° C.
3. For 100 kg of processed mass, we prepare 10 kg of bitumen and resin, bring to a boil.
4. Mix everything that's left.

Asphalt from previously used components is a cheap building material for the construction and repair of pedestrian and highways. With careful preparation of raw materials and proper laying, the wear resistance of such a coating does not differ from cold or hot asphalt.
