Asphalt crumb with delivery. Recycled asphalt Using asphalt crumb

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

Stages of application of asphalt concrete:

• specialized equipment removes the worn-out layer from the base;
• transportation of the received 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 a stationary technical base of the plant, but also when using mobile equipment. The described process of hot processing of secondary materials is not the only one, it is also widely used cold way... To do this, at the plant, individual pieces or other material obtained after milling the roadway is thoroughly crushed and mixed with fresh emulsion. The resulting material is used to create low-traffic roads, such as villages.

In our country, it is hot processing that is widely used, which is carried out using equipment from different foreign manufacturers. These batch plants are often mobile, which saves resources and time by eliminating plant involvement.

ABZ "Bernardi" with the system

recycling asphalt

The Italian company BERNARDI deserves special attention, creating state-of-the-art recycling plants. With the help of its advanced dryer, it is possible to regenerate up to half of the worn-out mixture. At the same time, the level of costs remains very low. The technology used in this unit is called "RED" and over the years of application has established itself as one of the best.

Another technology is used by the Chinese brand "D&G Machinery". This company uses classic time-tested technologies for the recovery of waste materials from road construction. 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 with its help no more than 35% (usually even less) of asphalt concrete can be recycled.

Before loading into such units, the raw material is crushed in percussion rotor, jaw or cone units (more details). To simplify the task of grinding high-strength material and to 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 - it is enough to add it to fresh mineral raw materials carefully dried in a special drum.

Technologically, the asphalt recovery process proceeds as follows:

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

The unit is operated by a trained operator at all stages of mortar recovery. In addition to the heater, this process involves the same equipment as for other types of asphalt concrete complexes. This makes it easy to set up the process of reclaiming asphalt concrete.

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 terrain improvement, we recommend buying asphalt crumb with delivery in Moscow, the price of which is the lowest of 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 asphalt chips - to Moscow or in the Moscow region, we will do it promptly 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 in 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 lots, territory zoning. 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. Silver-black chips are effective when 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 ramming 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.

Summer time of the year is chosen for road construction works. 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.

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 groceries 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 has 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 on road surface serious loads operate 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, water penetrated by 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 for asphalt concrete scrap

During the renovation works with the replacement of the roadbed, waste of asphalt concrete 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 in GOST there is no 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 up holes.

Much more the right decision there will be a reuse of old material in laying a fresh roadway. For this purpose, a special plant called a recycler is used, inside of 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 described in detail by GOST R55052-2012.

Keep in mind that the supplier may vary the price of granules, both upward and downward, depending on such 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 rationale of recycling old asphalt into new.

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 injection of a large amount of money. We can only hope that in the near future this practice will be extended to other industries.
