Asphalt pavement cold laying method

Abstract

The invention aims at providing an asphalt pavement cold laying method. An asphalt pavement wetting agent is sprayed and scattered to sufficiently wet asphalt among cold material particles, and primary viscosity is formed; and through sufficient grinding forming, the particles are closely attached, the wetting agent is dissolved in asphalt, fusing is performed on the asphalt on the surface of an asphalt cold material, the asphalt is solidified when drying and evaporating are performed on the wetting agent, the asphalt cold material is attached more and more firmly to asphalt of an existing pavement into a whole, high durability is realized, in the laying process, there is not need to perform hot laying through a traditional heating machine, and the laying cost is reduced. The problems thatwhen pits appear in an existing asphalt pavement, hot laying is needed for repairing the asphalt pavement, many machines and personnel are needed in the hot laying process, the repairing process is troublesome, the smell is strong in the laying process, and the environment is affected are solved.

Description

technical field [0001] The invention belongs to a pavement repair method, in particular to a cold paving method of an asphalt pavement. Background technique [0002] Asphalt is a low-temperature and easy-to-storage petrochemical scrap. After formula reorganization, today’s permeable asphalt is obtained. Because the permeable asphalt pavement has water permeability and noise reduction, and has the advantages of quick laying, it can be opened to traffic on the same day of laying and other functions. It is widely used Paving of road pavement. However, due to the need for hot laying, more machinery and personnel are consumed, and the smell is heavier during laying, which has a certain impact on the environment. During road operation, due to the need to bury pipe networks or modify road signs, street lamps, etc., it is necessary to break the road surface for construction. On the other hand, construction or vehicle heavy pressure may easily cause small pits and small dimples. Du...
