Use of recycled asphalt concrete for road construction. Recycling of old asphalt: features of different methods of recycling the road surface Methods of using asphalt crumb

Asphalt (asphalt) chips are recycled asphalt. The crumb looks like crushed stone, it is used for filling the road, parking lot, sites. Asphalt crumb is obtained by cutting asphalt pavement using a road milling machine. Particles of bitumen, which are present in asphalt chips, make the surface stronger after compaction. Due to the large amount of bitumen and crushed stone in the crumb composition, it rolls very well with a road roller, vibrating plate or car wheels. A road, a parking lot made of asphalt crumbs will last longer than from crushed stone because asphalt crumbs are less exposed to precipitation, is not washed away by rain, and does not form dust, such as limestone crushed stone. Asphalt crumb is also used as a base for asphalting , patching of roads, for major repairs of roads, dumping of roadsides. Our company "MskDor" offers to buy asphalt crumb at a low price per m3 from under the mill or from under the crusher (crushed crumb), it is possible with delivery and self-pickup from the site, sale in Moscow and the Moscow region.

Sizes of asphalt crumb: from 0.5 cm - 4.5 cm, small enough to fill roads for cars or paths in the country.

Asphalt crumb application:

• Road construction, for summer cottages and country roads
• Parking device, parking for cars

One of the most common recycled materials from recycling is asphalt chips, also known as asphalt granulates, and are used in a wide variety of construction and refurbishment jobs.

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

Use of asphalt crumb

Due to the inexpensive price, ease of use, as well as 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 life:

Due to the widespread use of this material, as well as the availability of many other options on the market, consumers, trying to find the most acceptable option for themselves, often ask the question of how much a cube of asphalt chips costs. Below in the abstract form are the main reference characteristics of this material, including answers to such questions as how much 1 cubic meter 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 crumb can weigh from 1500 to 1900 kilograms, depending on its composition;
• Accordingly, about 12 cubic meters will fit into the body of an average KAMAZ;

The consumption of crumbs 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 terrain is leveled, large debris is removed: cobblestones and scrap metal. It is quite possible to skip this point if the terrain condition is acceptable for this purpose.
2. Optionally, the surface is primed using bitumen emulsion of asphalt crumb for better adhesion in the future. Its consumption is about one liter per square meter;
3. Laying crumb on the surface, compaction of the laid layer. This can be done both with specialized equipment and independently. It is worth remembering that the compaction coefficient of asphalt crumb, depending on the composition, reaches a value of 2 units, which means that during rolling, the thickness can be reduced by 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 of about 0.5 liters per m2.

Asphalt crumb laying with my own hands 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 in cars. Difficulties may arise with how to melt asphalt crumb: 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 using asphalt crumb. Many people, from among those who will ennoble country cottage areahaving children and animals in the family, I wonder if asphalt crumb is 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 household is more environmentally friendly than in the case of asphalt of the same volume.

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 spheres 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 crumb as a suitable replacement for them;
3. Long service life when used in suitable conditions: secondary roads and short-distance tracks and sports complexes;
4. Ease of styling. For this, it is not necessary to prepare the surface in advance, and the rolling of asphalt crumbs does not imply the obligatory 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.

The disadvantages of asphalt crumb, like any other material, exist:

1. More harmful impact on the environment in comparison with gravel or sand;
2. The need for periodic updating of the canvas.

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

Alternative options

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

Summing up

Thus, the asphalt crumb will become for you ideal option, if you value simplicity and ease of installation and prefer to spend extra money on yourself and your loved ones, and not on building materials. For a parking lot or driveway, playground or garage floor, this material will meet your every need!

Secondary building materials have a significant economic advantage over primary ones. It should also be noted that the advantages of recyclable materials are technical and aesthetic characteristics. If you are deciding the issue of inexpensive landscaping, we recommend buying asphalt crumb with delivery in Moscow, the price of which is the lowest among a number of road decks.

There are three types of this secondary material: from under the cutter, from under the crusher and asphalt chips. All three types are in approximately equal demand on the secondary building materials market. Asphalt crumb price, which compares favorably with asphalt is irreplaceable material in road construction. This material is used very widely in the arrangement of road surfaces that do not have strict requirements for strength, such as for federal highways. Very often, a road made of asphalt crumbs can be seen at the dacha, in a garden partnership, cottage village or in an industrial area. MSC Region is a qualified supplier building materials... Our company has its own specialized vehicle fleet for the transportation of bulk building materials. Therefore, no matter where you need to deliver the asphalt crumb - to Moscow or in the Moscow region, we will do it quickly and efficiently.

Asphalt crumb cube prices

The above table shows the cost of material with delivery. Asphalt crumb price per cubic meter. meter with delivery in Moscow is usually purchased in bulk (in bulk). The cost of delivery of asphalt chips in Moscow and the Moscow region (Domodedovo, Mytishchi, Shchelkovo, Stupino, Podolsk, Chekhov, Lyubertsy, Odintsovo, Pushkino, Solnechnogorsk and other settlements) is calculated individually and depends on the delivery address.

Before ordering asphalt crumb or buying it for use in Moscow, Podolsk, Khimki, Dolgoprudny or elsewhere, further information will be useful.

Why is the cost of asphalt chips so cheap?

Because dear and necessary materialshave already been paid to create the initial coverage. Pricing is based on the cost of removing, transporting and recycling the old coating. As a rule, processing and crushing occurs directly when it is removed from the road. Therefore, the price of asphalt crumb is several times cheaper than the real cost of the components (crushed stone, bitumen, granite screening and sand). In addition, by using this product, you effectively solve the problem of recycling building materials, which is of global importance today.

Characteristics of the components of asphalt crumb:

• Crushed stone for road surfaces is most often used in fine and medium fractions (up to 45 mm). Long-term operation and bringing to marketable condition leads to additional grinding of stone grains. This contributes to a quality compaction.
• Bitumen is a polymerized substance obtained from petroleum products that has thermal, electrical and waterproofing qualities. Having no melting point, bitumen softens with a certain heating, after cooling it hardens and becomes solid. The most important properties for the road surface are the high adhesion and hydrophobicity of the recycled asphalt and bitumen.

Granite screening (screening of crushed stone with a grain size of 0 to 5 mm) and sand.

For any business executive, a reasonable price-quality ratio plays an important role. The density of the coating with the crushed substance is much higher than that of the original components. The high resistance of crushed stone and sand is enhanced by the adhesion of bitumen. Summer heat and sunshine provide additional education strong bituminous bonds. This all determines the maximum durability, weather and wear resistance. The crushed compound, distributed on the road, takes the necessary shape, fills holes and irregularities. The compacted secondary crushed stone and bitumen help to resist erosion and cracking of the road. When vehicles are driving, rubble, flying out from under the wheels, hits cars and creates noise. The baby does not have such disadvantages.

Application of asphalt crumb

Before ordering a car asphalt crumb at a low price (with delivery) in Moscow, you need to determine how it can be used? There are two main directions.

The first is construction. This is the construction of pedestrian and carriageways, sports grounds, parking, zoning of the territory. The scope in this direction is endless: courtyards, summer cottages, country roads, school and non-professional stadiums, parks and squares. Quite often it serves as a material for road repair: filling holes and cracks, strengthening roadsides.

The second is the design landscape design... Ornate paths created from this material will perfectly decorate your private property. In addition, paths made of fine asphalt are much more comfortable than gravel or crushed stones. The silver-black crumb is effective in framing and highlighting flower beds, shrubs, creating an alpine slide.

How to calculate the correct amount of material required?

The material is rolled twice, that is, if 20 cm is poured, after tamping it will turn out to be 10 cm. The value of the purchased material is equal to the area of \u200b\u200bthe covered surface multiplied by 0.2. The result is the number of required cubic meters... Additionally, possible parameters for holes and cracks are laid.

The summer season is selected for road construction work. A dry and dense base is the key to a good road. But cover secondary material does not imply the use of structures for loads like main lines. Therefore, the season is determined by the owner, but in any case not at the time when the soil (base) is frozen.

Asphalt crumb is a material used today in road construction and road renovation works... The popularity of this material is growing day by day, due to its properties and affordable cost. Asphalt crumb is obtained by artificial crushing of the asphalt pavement. Moreover, as a rule, the old, worn out asphalt surface, which is no longer suitable for driving, is subjected to grinding.

A special technique called a milling cutter is used to remove old asphalt pavements. This is a road machinery that, under the control of specialists, cuts the top asphalt layer from the road, and immediately crushes it, turning it into asphalt chips. This process is called road milling and it is very relevant when overhaul road or its restoration.

In fact, asphalt crumb is a secondary raw material, as it is the result of recycling old asphalt pavement. This can explain its low price.

Perhaps the main advantage of asphalt crumb is that it has all the properties of asphalt. Its fine particles are easy to work with, and asphalt chips are easy to compact and tamp. And the bitumen particles that it contains make it possible to create additional lighting on the roadway at night, due to its ability to reflect the headlights of cars passing along the road.

The cost of asphalt crumbs from 955 rubles m3 with delivery in Moscow.

Currently, much attention is paid to landscaping, for example, asphalting roads. At the same time, preference is often given to the most economical options.

The secondary material used in road construction - asphalt crumb - is formed by crushing cracked asphalt with a special machine. In this case, the method of cold milling or crushing of the removed road surface is used, which is called asphalt scrap. The result of these procedures is a mixture, which includes crushed stone, sand, bitumen residues. The technological value of asphalt crumb is due to the presence of bitumen in it, which enhances intergranular bonds, thereby improving the physical and mechanical characteristics of the roadway, in the construction of which this material was used.

Ways of using asphalt crumb:

• Production of cold AGB-mixtures (asphalt-granular concrete mixtures) - asphalt crumb is part of this material, which is used in cold regeneration. It should be noted that this technology involves the restoration of damaged roads by milling outdated pavement;
• The production of hot AGB-mixtures - asphalt crumb, which can be ordered from our company, participates in the hot regeneration process. Distinctive feature This technology is the preheating of asphalt concrete before milling. This way you can update the top layer of the road;
• Construction of a base characterized by low strength properties - this procedure is performed if necessary to asphalt a small area;
• Creation of temporary road surfaces, technological passages and other structures, which are characterized by a low traffic load. In this case, the material used retains a loose structure throughout the entire operational period.

Where is the best place to buy asphalt crumb?

You can buy asphalt crumb in Moscow and the region on favorable terms in the ASPHALT TECHNO company. We have quite a lot of experience in working with this material. We have repeatedly carried out road repairs, engaged in the construction of the roadbed, and carried out filling of various sections.

Transport infrastructure is one of the most important systems of any state. With its help, trade between cities is carried out. This is how the products most likely arrived at your nearest store. Therefore, maintaining the road in the best possible condition is necessary to meet all transport needs.

The first builders of roads under the understanding that we know today were the Romans. During the time of the Roman Empire, they were concerned about the need to build trade routes to their capital from all over the empire. There is a saying confirming this: "All roads lead to Rome." This can be seen on the historical map.

It is worth noting that they approached this issue thoroughly, even after thousands of years there are well-preserved parts of it. We need to thank the designers who pointed out the need to create a solid foundation. It provided reliability for centuries. On top, either smooth slabs or a scattering of small stones were usually placed.

In our time, the process of building roads has become more technological. This is done both to give a smooth surface and to increase the life of the web. All factors affecting service life are calculated by engineers. This must be taken into account, since serious loads act on the road surface around the clock. In summer high temperatures they simply "melt" the asphalt as a result of which a track appears from the wheels. During the first frost, the water penetrating the cracks freezes and turns into ice, and, as is known from school course physics ice has a larger volume than water. Therefore, the water literally tears the road apart.Another advantage of modern roads is the speed of repair. A flawed place can be repaired in just one hour.

Sorting process of asphalt concrete scrap

During the repair work with the replacement of the roadbed, asphalt concrete waste is generated different sizes... This sometimes complicates the processing process, since not all construction machines able to grind large blocks of asphalt. For this, a conditional classification of sizes was invented. It is called conditional due to the fact that GOST does not contain a column with an exact indication of the values. There are usually three groups of reclaimed asphalt lumps:

• Small fragments - up to 150mm;
• Medium wreckage - up to 400mm;
• Large scrap - from 400mm.

Perhaps these conventions were not documented due to the fact that most often the workers have to grind the fragments themselves to the required size at the place of repair work.

Natural asphalt is a mixture of bitumen with various minerals.

Utilization and further use of asphalt scrap

The concept of recycling asphalt scrap means only its processing. The material is very durable, it has no limit on the number of re-uses. Therefore, simply throwing the old asphalt into a landfill will not be the most rational solution.

Use in construction

Asphalt scrap is a fairly versatile material in construction. With the help of it, you can strengthen roads that are not paved, or simply fill in holes.

Much more the right decision there will be re-use of old material in the laying of fresh roadway. For this purpose, a special plant called a recycler is used, inside which asphalt is recycled. More specifically, it heats the mixture and mixes it until smooth. Approximately as a concrete mixer. To achieve the best quality product, you must strictly observe temperature regime... Externally, the installation has an unremarkable appearance: a barrel painted in orange color, which is mounted on the chassis from the trailer. There are many models of such stations, up to self-propelled ones, but the described type is the most common. This allows it to be mobile enough that it can be used in the narrow streets of the city.

Prices for asphalt concrete scrap

Waste from asphalt concrete production has a fairly low cost in the construction market. For example, one ton of untreated waste will cost only 200 rubles. This means only removed lumpy asphalt, usually large sizes... Asphalt chips are much more expensive, about 1000 rubles. This is logical, since it is already a full-fledged repair and construction material.

There is also the concept of asphalt granulate, it differs from crumbs in more thorough preparation in the form of crushing, as well as screening in specialized installations. All information is prescribed in detail by GOST R55052-2012.

Keep in mind that the supplier may vary the price of granules, both upward and downward, depending on the following factors:

• Seasonality;
• Volumes of purchased material;
• The quality of the product provided.

Another cost stanza is the transportation of freshly acquired material to the work site. This fact once again proves the whole reasonableness of processing old asphalt into new one.

Conclusion

Thus, we have clarified the importance of recycling and secondary use waste. Especially if this process is simple enough and does not require the infusion of a large amount of money. We can only hope that in the near future this practice will be extended to other industries.
