Asphalt crumb with delivery. Recycled asphalt

In the field of repair and reconstruction roadbed in practice, the effectiveness of the application has been proven secondary asphalt concrete. Due to the content of bitumen, stone, plasticizers in such material, asphalt regeneration is expedient not only from an economic, but also from a technical point of view. Additionally, such an event saves energy and resources. Secondary materials attracted the attention of builders because the cost of the bitumen and mineral components used in them is quite high.

Stages of application of asphalt concrete:

• specialized equipment removes the worn layer from the base;
• transportation of the obtained material to the asphalt concrete plant;
• heating the secondary product, in some cases it is mixed with a fresh portion of bitumen or other raw materials.

This process can take place not only in the conditions of a stationary technical base of the plant, but also when using mobile equipment. The described process of hot processing of recycled materials is not the only one, it is also widely used. cold way. To do this, at the factory, individual pieces or other material obtained after milling the roadway are carefully crushed and mixed with fresh emulsion. The resulting material is used to create roads with a low level of congestion, for example in villages.

In our country, it is hot processing that is widely used, which is carried out using equipment from various foreign manufacturers. Such batch plants are often produced mobile, which reduces the cost of resources and time, excluding the participation of the plant from the process.

recycling asphalt

Particularly noteworthy is the Italian company BERNARDI, which creates state-of-the-art recycling facilities. With the help of its advanced dryer, it is possible to regenerate up to half of the worn mixture. At the same time, costs remain very low. The technology used in this unit is called "RED" and over the years of use has proven itself to be one of the best.

Another technology is used by the Chinese brand D&G Machinery. This company uses time-tested classical technologies for the regeneration of waste road construction materials. All installations produced by the brand can be divided into two main categories. The first is equipment with a parallel drying element, which guarantees the processing of a large percentage of recyclable materials (50% or more). This technique requires a significant investment. The second option is a recycling ring, which is an order of magnitude cheaper, but it can be used to recycle no more than 35% (usually even less) of asphalt concrete.

Before loading into such units, the raw material is crushed in impact rotary, jaw or cone units (more details). To simplify the task of grinding high-strength material and speed up this operation, it is saturated with water. It is preferable to carry out crushing in a cold or moderately warm environment, the temperature of which does not exceed 15 degrees Celsius. If we are not talking about lumpy material, but obtained by milling, it is not necessary to grind it - just add it to fresh, thoroughly dried mineral raw materials in a special drum.

Technologically, the asphalt recovery process proceeds as follows:

• fresh mineral base is dosed and placed in a drum-type heater;
• old materials are loaded into the same container: asphalt dust, bitumen fragments, crushed lumpy raw materials;
• all this is heated to strictly defined temperatures (to avoid the rapid aging of the mixture) and mixed with a fresh portion of bitumen or plasticizer;
• after preparation of the mixture, it is unloaded into lifting device skip type, transported to the bunker of finished materials.

The installation is controlled by a trained operator at all stages of the restoration of the building mix. In addition to the heater, the same equipment is involved in this process as for other types of asphalt concrete complexes. This makes it easy to set up the process of regeneration of asphalt concrete.

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

This secondary material is of three types: from under the cutter, from under the crusher and asphalt chip. All three types are in approximately the same demand in the secondary building materials market. Asphalt crumb price, which compares favorably with asphalt is indispensable material V road construction. This material is used very widely in the arrangement of road surfaces that do not have strict requirements for strength, such as federal highways. Very often, a road made of asphalt chips can be seen in the country, in a garden partnership, cottage village or in an industrial area. MSK Region - 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 asphalt chips - to Moscow or the Moscow region, we will do it promptly and efficiently.

Prices of a cube of asphalt crumb

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

Before you order asphalt crumb, or buy, for use in Moscow, Podolsk, Khimki, Dolgoprudny or elsewhere, further information is useful.

Why such a cheap cost of asphalt chips?

Because dear and necessary materials, to create the initial coverage have already been paid. 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 chips is several times cheaper than the real cost of the components (crushed stone, bitumen, granite screenings and sand). In addition, 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 small and medium fractions (up to 45 mm). Long-term operation and bringing to a marketable condition leads to additional grinding of stone grains. This contributes to high-quality tamping.
• Bitumen is a polymerized substance obtained from petroleum products, which has thermal, electrical and waterproofing qualities. Having no melting point, bitumen softens with a certain heating, after cooling it solidifies and becomes solid. The most important properties for paving are the high adhesion and hydrophobicity of recycled asphalt and bitumen.

Granite screening (crushed stone screening 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 coating density of the crushed substance is much higher than that of the original components. The high stability of crushed stone and sand is enhanced by the adhesion of bitumen. Summer heat and sunshine provide additional education strong bitumen bonds. All this determines the maximum durability, weather and wear resistance. The crushed composition, distributed on the road, takes the necessary shape, fills the pits and bumps. Compacted secondary crushed stone and bitumen contribute to the resistance to erosion and cracking of the road. When driving vehicles, crushed stone, flying out from under the wheels, hits cars and creates noise. The crumb does not have such shortcomings.

The use of asphalt chips

Before ordering an asphalt crumb machine at a low price (with delivery) in Moscow, it is necessary 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 lots, zoning of the territory. The scope in this direction is limitless: courtyards, 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.

Second - decoration landscape design. Ornate paths created from this material will perfectly decorate your private property. In addition, fine asphalt paths are much more comfortable than gravel or crushed stone ones. Silver-black chips are effective when framing and highlighting flower beds, shrubs, creating an alpine hill.

How to correctly calculate the amount of material needed?

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

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

Transport infrastructure is one of the most important systems of any state. With its help, goods are exchanged between cities. This is how the products most likely arrived at your nearest store. Therefore, keeping 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 that confirms 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 sections of it. We need to thank the designers who pointed out the need to create a strong foundation. It provided reliability for ages. From above, either smooth slabs or a scattering of small stones were usually placed.

In our time, the process of building roads has become more technologically advanced. This is done both to give a smooth surface and increase the life of the blade. Engineers calculate all the factors that affect the service life. 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 from the wheels appears. During the first frosts, the water that penetrated 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 defective place can be repaired in just one hour.

The process of sorting asphalt concrete scrap

During the repair work with the replacement of the roadway, asphalt concrete waste is generated different size. This sometimes complicates the recycling 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 in GOST there is no column with an exact indication of the values. There are usually three groups of pieces of recycled asphalt:

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

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

Natural asphalt is a mixture of bitumen with various minerals.

Recycling and further use of asphalt scrap

The concept of recycling asphalt scrap implies only its processing. The material is very durable, it has no limit on the number of reuses. So just throw away old asphalt to a landfill would not be the most rational solution.

Use in construction

Asphalt scrap is a fairly versatile material in construction. With it, you can strengthen roads that do not have a hard surface or simply fill in holes.

Much more right decision there will be a reuse of the old material in the laying of a fresh roadbed. To achieve this goal, a special installation called a recycler is used, inside which asphalt is processed. More specifically, it heats the mixture and mixes it until it is homogeneous. Approximately, as a concrete mixer. To achieve the most quality product must be strictly observed temperature regime. Externally, the installation has an unremarkable appearance: a barrel painted in Orange color, which is installed on the chassis from the trailer. There are many models of such stations, up to self-propelled ones, but the type described 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

Asphalt production waste has a fairly low cost in the construction market. For example, one ton of raw waste will cost only 200 rubles. By this is meant only the removed lumpy asphalt, usually large sizes. Asphalt crumb is 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 granulate, both up and down, depending on such factors:

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

Another cost line is the transportation of freshly acquired material to the place of work. This fact once again proves the wisdom of recycling old asphalt into new one.

Conclusion

Thus, we found out the importance of recycling and reuse waste. Especially if this process is quite simple and does not require the infusion of a large amount Money. We can only hope that in the near future this practice will be extended to other industries.
