Generally speaking, the pavement that has been subjected to heavy traffic for a long time will have subgrade damage. In order to eliminate this damage, the whole pavement needs structural maintenance. The pavement cold recycling machine reuses all milled materials, and its economic treatment method makes the use of foam asphalt for cold recycling construction a pioneering solution to achieve environmental protection and economy.
Composition and working principle of pavement cold recycling machine
Composition: pavement cold recycling machine is the main equipment in the construction of asphalt pavement cold recycling, which is generally composed of power system, transmission system, working device, spraying system and operation control system.
Working principle: when the pavement cold regenerator moves forward, the rotor rotates upward to mill the raw pavement materials. At the same time, water is conveyed from the water truck connected to the pavement cold regenerator through a hose and sprayed in the mixing bin of the pavement cold regenerator. The delivery volume of water is controlled by the microprocessor controlled pumping system to achieve the required water content. The milling rotor will fully mix the water with the milling material. Liquid stabilizers, such as hot asphalt (the cold regenerator has its own foam asphalt foaming device, which can heat the hot asphalt to 160-180 ° C and mix it with a small amount of water for foaming), can be sprayed into the mixing chamber through a specially designed spray nozzle; Powdered stabilizer such as cement shall be sprinkled on the road surface in front of the road surface cold recycling machine according to the designed addition amount. The road surface cold recycling machine will mix the powdered stabilizer with recycled materials and water at one time. If the original grading of the recycled layer is poor, the missing part of the aggregate can be sprinkled on the pavement before regeneration, and the grading of the original pavement material can be improved by mixing with the old material.
