Pothole repair of asphalt concrete pavement. Application of asphalt, technology of its laying and repair Road patching

You can often see a road crew on city streets repairing asphalt pavement by filling holes and potholes. Such repairs are carried out at any time of the year.

The main causes of damage to asphalt pavement

It is necessary to carry out when the asphalt covering is partially destroyed. It can be caused by various factors:

  • long-term and intense load on the road surface (large daily traffic flow);
  • the composition or structure of the asphalt pavement does not correspond to the loads on it;
  • damage to asphalt from mechanical impact;
  • the coating is damaged due to repair and restoration work carried out by utility services (replacement of communications, elimination of pipe ruptures);
  • roots of nearby greenery;
  • destruction of asphalt from regular exposure to fuels and lubricants.

Partial “delamination” of the asphalt pavement can be caused by impaired production technology of the composition. This may be due to an insufficient amount of bitumen in the mixture or violations were made when laying the asphalt pavement.

It is necessary to carry out “hole-and-patch” repairs so that the coating does not deteriorate even more, which will lead to a complete replacement of the asphalt covering of an entire section of the road.

Technological process of pothole repair

Such repairs are quite simple and consist of several stages: marking the area, cutting down and cleaning the hole, paving potholes.

Preparatory work:

  • First, the areas of damage are marked; for this purpose, a schematic map is drawn up for repairing the holes. The areas of the damaged section of the road where asphalt replacement is needed are identified with rectangular figures.
  • Then the marked rectangles are cut down and cleaned to a depth of 15 cm using jackhammers and seam cutters. In cases where the damage is extensive, equipment designed for these purposes is used.
  • After cutting down, the quality of laying the coating is checked, possibly main reason destruction in a poorly laid base or its complete absence. When the base is there, just add crushed stone and compact it. If there is no “cushion” of crushed stone, the pothole is cleaned of dirt and the base is made anew. Before filling potholes, their edges are treated with bitumen to better bond the old asphalt layer to the new one. If a large area of ​​the road is damaged, cutting and dismantling is carried out using an excavator.

The process of asphalting pits

If the pothole is small, it is repaired manually, filling the asphalt mass with special rakes. Compact and level the area covered with asphalt using hand rollers or vibrating plates. Large potholes are filled with an asphalt paver and compacted with a roller.

The road surface is 30-40% more than full asphalting of the road due to the use of manual labor.

Even the most reliable coating device fails sooner or later. Asphalt is a soft material that tends to wear out. Upper layer The coating is called a “wear layer”. Laying asphalt with replacement of side stones is used if the number of defects in the road surface exceeds 12-15%. For smaller scale damage, asphalt patching is carried out, which will ensure safe and comfortable driving on the road at a low cost. It is the filling of holes that is the most common type of current asphalt paving. The quality of repair work directly depends on adherence to technology and the choice of asphalt concrete mixture.

Asphalt– the most popular material for creating road areas. Its reliability and practicality have been tested over the years. The variety of brands makes it possible to create road surfaces in Moscow on highways, intercity highways, yard communications, and sidewalks.

Different methods of filling holes and potholes on the road

Construction technology is constantly being improved, new additives appear in the asphalt concrete mixture that prevent damage road surface and reduce the cost of operating transport networks. Small cracks inevitably increase in size due to sudden temperature changes. When water gets inside road slabs, it expands when it freezes and breaks the pavement structure, turning a small pothole into damage the area of ​​which is measured in m2. Therefore, road patching is important work to preserve their performance, which we will do for you at the highest level.

Pothole work with hot mix asphalt

Hot mix asphalt concrete and cast asphalt, prepared from sand, crushed stone, bitumen and mineral additives, are used to repair roads of the first and second categories. The mixture heated to 150 degrees is delivered to the site in specialized bunkers that can hold up to 4 m 3 of product. A mixture that has cooled below 110 degrees is considered defective. Transcom cooperates with many asphalt concrete plants and has the ability to quickly deliver the mixture even to remote sections of roads under construction. The universal hot method is affordable, but has one significant drawback. Repair work can only be carried out in the warm season and in dry weather.

Preparatory work before pothole repair of asphalt consists of the usual set of operations:

  • leveling
  • cleaning
  • priming the surface of the concrete base

Laying and compaction of mixtures is carried out by specialists using standard equipment: asphalt pavers and rollers. The asphalt surface after the passage of equipment has a smooth texture without cavities, cracks, tears and other defects.

Cold road repair

Cold asphalt refers to mixtures that are higher in price per unit than traditional ones. measurements. They contain special additives, bitumen. For each component, a special temperature regime is provided during the preparation of the mixture. The cost of cold bitumen-containing composites is compensated by the versatility of use. Work is carried out at any time of the year, including at sub-zero temperatures. Preparation involves removing dirt and excess moisture from the crack or hole. Cold asphalt does not require additional compaction. The movement of vehicles through the repaired area will provide the necessary density to the coating.

The strength and water resistance of cold mixtures is lower than hot ones, so they are used for repairing roads of the third and fourth categories. Pothole repair at a reasonable price per m2 using bitumen emulsions is relevant for emergency repairs and repair of minor defects.

A mixture of sand, gravel and ground limestone with sufficient big amount Natural and petroleum bitumen is called cast asphalt. The mass is easily smoothed by hand due to its mobility when hot.

The liquid consistency ensures the installation of a dense cast layer that does not require additional compaction. The high moisture resistance of the coating allows you to seal potholes even during precipitation. Casting temperature - 180-250 degrees. Excess moisture on the base at this temperature instantly turns into steam, the edges of the coating are fused into a single whole with the mixture being poured. Cast asphalt is ideal for emergency work in freezing temperatures and during rain. Call Transcom, our specialists will help you choose the most convenient way paving for each specific case.

Recycling and jet injection methods

Economical modern technology involves the processing of asphalt concrete material and its use for repairs road surface directly on site, without removal of materials. The asphalt dismantling products are heated and mixed in a specialized machine, a recycler. Bitumen is added to the asphalt crumbs and used immediately. The use of this practical technology, instead of using a sand cushion and fine-grained crushed stone, reduces the price per m2 by half.

Jet-injection technology involves performing all existing repair operations with one machine. The repair area is subjected to blowing with a high-speed air stream, instant washing and application of bitumen emulsion. Milling of asphalt concrete is not carried out. The pothole is filled with small crushed stone and bitumen emulsion. High speed air flow ensures good compaction without vibration rolling.

How to prepare a road for pothole repair

The main key to success is compliance technological requirements and standards defined for each type of mixture.

  • Potholes and cracks are marked with straight lines along the axis of the road and across it. The reserve of the undamaged layer should be at least 3-5 cm.

  • Removing coating from small potholes using a jackhammer. Removing coating from narrow potholes, the length of which exceeds 3 m2, is done using a cutter.

  • The pits are cleared of crumbs and dust. The walls are treated with liquid bitumen or emulsion. There should not be too much liquid, otherwise the quality of adhesion of the new layer to the old one will decrease.

The prejudiced attitude towards filling potholes is largely due to a careless attitude towards the construction of foundations. High quality work done on long years rid the asphalt concrete surface of potholes, allowing you to move comfortably on repaired roads.

Asphalt pothole repair

Pothole restoration of the road allows you to carry out repairs with minimum cost resources. Pothole repair is used if the damage to the asphalt surface is less than 15%, and the diameter of the holes does not exceed 25 square meters. The depth of filling the hole with asphalt emulsion is 5 cm and is sufficient for Moscow roads.

The cost of road repairs in Moscow starts from 570 rubles.

For road repairs, the price is calculated during the marking process. Identification of holes and calculation of the dimensions of rectangular cards for dismantling and applying patches allow you to accurately determine the square footage and announce the price.

Timing for asphalt patching repairs

One of the advantages of pothole restoration is the ability to quickly restore the coating. Repairs do not require adjusting large equipment and blocking traffic. The scope of work during restoration is minimal and consists of only three main stages - preparation, dismantling and asphalting.

To restore the road surface as quickly as possible, the Undorstroy company works:

  • around the clock;
  • no days off;
  • on holidays.

Carrying out pothole repairs of roads in Moscow and the region in most cases does not require blocking the route. We level the surface one at a time on different lanes. Partial overlap allows you to avoid creating obstacles to the movement of cars during the work.

The only limitation is the condition that road repairs are carried out only at above-zero temperatures and dry weather. Otherwise, it is impossible to guarantee the durability of the patches and high performance.

Why is it worth ordering road repairs from Undorstroy?

You can order the services of the Undorstroy company by contacting us by phone and arranging a meeting with a consultant, or by leaving a request on the website. At our disposal:

All our employees are regularly certified for their ability to perform road repair work. Our fleet has our own equipment of any size, from vibrating plates and compactors, to asphalt pavers and 10-ton rollers.

The Undorstroy company independently produces recycled crushed stone and processes asphalt to reduce the price for customers. We started our work in 2001, and maintain a reputation as a reliable partner for the construction and repair of roads in Moscow.

Technology for pothole repair of asphalt pavement

After agreement with the customer, we send necessary equipment and certified specialists at the site of road surface repair. Upon arrival at the site for pothole repair in Moscow, our specialists block one of the traffic lanes.

After installing fences, signs and organizing detours, qualified workers immediately begin repairing the road. Removing potholes includes several stages:

  1. Marking
  2. Sawing cards
  3. Dismantling the coating
  4. Cleaning the base
  5. Asphalting
  6. Cleaning the area

Markings are applied to determine the scope of work, calculate the cost and mark damaged areas. A cold asphalt mill passes along the finished markings, cutting even rectangular cards for patches around the hole.

Cutting is necessary, since microcracks in the canvas take up large area than visible damage. The contour of the dismantling card is usually 20 cm wider than the excavation area. Cutting with a milling cutter does not exceed the width of the traffic lane, even with large cracks, so as not to create obstacles to traffic.

After passing the contours of the rectangle for the patch, the recess is cleared of the resulting crumbs, usually manually, using a jackhammer in the center of the map. The Undorstroy company removes and accepts asphalt chips from the site free of charge. With us you can reduce the cost of road repairs during dismantling.

Cleared of chips, dust and debris, the rectangular excavation is prepared by the Undorstroy company to create a load-bearing layer, using recycled crushed stone of its own production. Additionally, treatment with hot bitumen emulsion is possible to strengthen the base and form a layer.

The prepared area is covered with asphalt by road workers with the necessary qualifications. The patch is applied using hand shovels, using special equipment - kochers, which do not allow the finished asphalt to harden.

An asphalt smooth drum roller may pass behind the workers. For small volumes of work, road builders use mobile vibrating plates for local pothole repair of the road surface.

Compacted asphalt pavement does not require waiting to harden. After completion of the work, construction equipment and debris are removed, and fences are removed. The traffic flow along the strip can be restored, and the workers move on to the next part or hand over the object to the customer.

Rassvet LLC carries out all types of asphalt pavement repairs and offers competitive prices. We carry out road restoration work in Moscow and the Moscow region.

The company accepts orders for execution complex works with preliminary diagnostics and road patching. The technology is selected depending on the degree of wear of the roadway, traffic flow and the availability of bypass routes, and timing.

  • pothole repair of asphalt pavement;
  • distribution and leveling of the leveling layer followed by compaction.

Depending on the condition of the roadway, the list of works may be adjusted.


Asphalt patching is an affordable way to level the road

Filling road cracks and potholes is a minimal amount of repair work. Pothole repair of asphalt pavement can be one of the stages of road restoration, but in case of occasional damage it is used without laying a top wear layer to reduce cost.

Defects are sealed with hot or cold asphalt concrete mixture. It is convenient to use a hot compound when subsequently applying a wear layer, since there is no need to take a break between these operations. Pothole repair of roads with a cold mixture is most often carried out without laying additional covering, since this requires a pause of 10 days. The cold compound is applied without subsequent compaction; this occurs during the further operation of the road. This method of restoration has a low price.

We level the road surface. It can be produced mechanically using special equipment equipped with a cutter. In case of significant unevenness, laying a leveling coating is required. Depending on the size of the depressions, fine- or coarse-grained mixtures are used for asphalt repair.

Rassvet LLC ensures quality control of materials used in repair work and strictly adheres to the necessary temperature regime. We have a diverse selection of special equipment for the application of any technology.
