Cold recycling lines

  • Replaces up to 20% of inert materials with crumbs from old asphalt
  • Low cost compared to hot regeneration lines
  • Low final product cost
  • Possible installation at already existing plant

01 Cold recycling lines RAP

Cold recycling technology is a promising direction of development of domestic road construction. Using the old asphalt surface removed from the road being repaired for asphalt-concrete mix preparation, cold recycling technology allows to produce without additional heating (using astringent and additional fractions) high-quality asphalt concrete ready for use. At the same time, there is a significant decrease in the cost of work and final product.

Cold recycling is regarded as an attractive technology for restoring road clothes by the “cost/efficiency” criterion, including due to its economy and environmental friendliness. The construction resource for the new road in this technology is old road bed, the amount of imported materials is minimal. In addition, the use of this technology allows a significant reduction in repair time (3-5 times faster than conventional methods).

As a rule, this technology is suitable for the repair of roads of local importance and roads 3 and less technical categories with low traffic intensity.

Cold recycling lines units:


The mixing unit is an important element in an asphalt mixing plant, the quality of which directly affects the quality of the asphalt concrete produced. It consists of a mixer in which the ABS ingredients are mixed, as well as a system for feeding and dosing materials. It is intended for transportation of heated sand and crushed stone to the screen, sorting and dosing of stone materials, dosing of bitumen, mineral powder, dust, preparation of asphalt concrete mixture and unloading it into vehicles or storage hopper.

Power supply unit

The power unit is responsible for feeding the components of the asphalt mixture into the Tumble dryer. It consists of several elements: feeding silo with feeders (designed for storage and dosing of asphalt mixture components, such as crushed stone, sand, etc.); conveyors (used to transport components from feed bins to a drying drum); feeders (provide accurate dosing of each component of the asphalt mixture, which allows you to get a quality product).

Dust cleaning system

The system includes a bag filter unit of mineral powder and dust.

The bag filter is a unit in a dust-protected housing in which the sleeves of the Nomex DuPont filter material are mounted. The air is filtered by the smoke and the passage of dusty gases through the filter material of the bag. The sleeves are regenerated (the accumulated dust layer is dropped from the filters into the hopper) by means of flaps which open by the pneumatic cylinders above the filters and by the exhaust pipe being pulled through the purge channel.

Bitumen storage

Designed for storing and heating bitumen. Available in horizontal and vertical design. Has different volume: from 20 to 100 m3.

Each container has thermal insulation, register system, filling indication, technological manholes. Thermal oil is used to heat the storage, which improves the quality of bitumen preparation by avoiding overheating and coking. The oil is heated to the desired temperature by means of a heater of a liquid heat transfer medium. At the customer’s request, the heating system in the tanks can be carried out with the help of electric heating elements.

Tumble dryer

The drying drum together with the furnace and dust collector with bag filters is part of the integrated drying system. Designed for drying and heating stone materials to the temperature necessary for the preparation of the mixture. The TTM design office has selected the optimal linear dimensions of the combustion chambers of drying drums, the capacity of burners, which ensures the production of dried and warmed material even in high humidity conditions.

The barrel and blades are made of boiler steel, bandages and support rollers using forging technology. The drum cigar is insulated with aluminosilicate heat-insulating cotton and is covered with stainless steel plates. This exterior finish reduces heat loss, is efficient, environmentally friendly and durable.

Vibration screen

Vibration screen is another important element of the asphalt mixer, which is used to separate stone materials into different sizes. The screen consists of several layers of screens, each of which has holes of a certain diameter. Stone materials are loaded into the top of the rumble and pass through all tiers where they are divided into factions. The resulting fractions are sent to the respective bunkers for further use in the asphalt mixing process.

The APC TTM is equipped with a 4-,5- or 6-fraction vibration screen, which is developed according to the European standard with two WAM vibrators (Italy), braided sieves and pre-tensioners. Such a design significantly increases the life of the unit, eliminates the sagging of screens, increases the quality of dispersion. It’s possible to work without the vibration screen.

Inert material dispenser, bitumen dispenser, powder and dust dispenser

The Hopper

The hopper is a special tank designed to store the finished asphalt concrete mixture.

The hopper is of two types and consists of 2 and 3 compartments for different asphalt brands: - tower type with bunker capacity from 30 to 200 tons - removable type with a capacity of 50 to 200 tons

The equipment of the material storage bunker is located in the lower part of the modular design. The equipment occupies a small area, transportation and installation are optimized, and environmental-saving equipment is more convenient.


The TTM burner is a development of our factory. The burner is designed for use in a specific drying drum. This allows us to achieve maximum efficiency. What we’ve achieved is that the fuel burns completely, giving all the energy to dry the inert materials. The burner control system is integrated into the AMP control system.

The TTM factory produces liquid, gas and combined burners. All gas equipment has been certified in the Russian Federation. Due to the fact that fuel quality is often below the stated standards, our factory conducted a study, on the basis of which 4 patents were protected and the design of the burner was improved.

Operator's cabin

The operator’s cabin, in which the control units are located, is simple and concise, well thought out and as effective as possible. The cabin itself is made of sandwich panels, providing excellent heat and noise insulation, as well as protecting operators and equipment from dust intrusion. On three sides the cabin is equipped with sound and heat-tight wide windows that provide excellent visibility. In this case, the working space and the control cabinet itself are located in different areas, between which are installed insulating doors, safety and locking devices to minimize risks in case of improper operation. Both rooms are air-conditioned.
