Low-noise anti-skid road surface processing method

Abstract

A low-noise anti-skid road surface processing method is provided, which takes a highway as a construction object and includes steps of: closing a construction section of the highway, and then disease-treating and cleaning a road surface of the construction section; through a construction vehicle, synchronously sprinkling an interlayer interface agent, modified emulsified asphalt, an anti-skid noise-reducing material, modified emulsified asphalt and a surface protection agent which are successively distributed in a multi-layer manner to the road surface, and forming an ultra-thin overlay structural layer with a thickness of 2-9 mm on the road surface. The present invention is able to prevent the flying stones easily occurred in the gravel seal from affecting driving safety, and overcome the flaking off easily occurred in the prior art, so that it is a ultra-thin surface processing technology with fast construction and effectively cost.

What is claimed is: 
     
         1 . A low-noise anti-skid road surface processing method which takes a highway as a construction object and comprises steps of:
 (1) closing a construction section of the highway, and then disease-treating and cleaning a road surface of the construction section;   (2) through a construction vehicle, synchronously sprinkling an interlayer interface agent, modified emulsified asphalt, an anti-skid noise-reducing material, modified emulsified asphalt and a surface protection agent which are successively distributed in a multi-layer manner to the road surface, and forming an ultra-thin overlay structural layer with a thickness of 2-9 mm on the road surface; and   (3) after drying the ultra-thin overlay structural layer, rolling the road surface for 1-4 times through a rubber tire roller, and then maintaining, and finally opening traffic.   
     
     
         2 . The low-noise anti-skid road surface processing method, as recited in  claim 1 , wherein: in the step (2), a weight ratio of the modified emulsified asphalt, the interlayer interface agent, the anti-skid noise-reducing material, and the surface protection agent is (6-20):(1-3):(20-50):(1-5). 
     
     
         3 . The low-noise anti-skid road surface processing method, as recited in  claim 1 , wherein: the modified emulsified asphalt is prepared by mixing and emulsifying an emulsifier, asphalt, a modifier and water with a weight ratio of (1-3):(50-60):(5-10):(30-40). 
     
     
         4 . The low-noise anti-skid road surface processing method, as recited in  claim 1 , wherein: the interlayer interface agent contains an emulsifier, a polymer bonder and an asphalt regeneration agent/a cement reinforcing agent. 
     
     
         5 . The low-noise anti-skid road surface processing method, as recited in  claim 1 , wherein: the anti-skid noise-reducing material is prepared by mixing basalt or a diabase stone material, with high elastic rubber particles and a hydraulic cementitious material. 
     
     
         6 . The low-noise anti-skid road surface processing method, as recited in  claim 1 , wherein: the surface protection agent comprises special resin, polymer binder, anti-sticking agent, surface active agent, solvent and water.
