Research On Material Performance Of Cold Patch Asphalt Mixture In Cold Area

The asphalt concrete pavement will be damaged by the vehicle and various natural factor function rain, because of facing the layer aging, the basic level glint crack, rain snow erosion, layer combine a series of reason of not good etc. Therefore that should take into the repair in time with the instauration the neat that road face, keep good image of the city road. Currently, repair the road to face the pit to adopt the heat to mix the asphalt admixture to anticipate mostly, it is convenient with bigger road of concentrated amount of engineering of district face maintain, but for district scatter small road of amount of engineering face maintain, special in the winter and rain waters more spring, the repair material and the repair techniques that asphalt road face are still topics that needs the research. Cold repair the asphalt admixture to anticipate to have asphalt mix with anticipate prepare mix good. advantage, can satisfy the demand of the high grade highway repair. Therefore, in recent years, the exhibition in succession at home and abroad cold repair the research that the asphalt admixture anticipate, obtain the certain result, but its function still treats further fashionable.This paper according to cold repair the technique characteristics of the asphalt material, analyze cold repair the material of constitute and strengths, and check up the performance of cold repair road surface. At the same time, analyzed to affect cold repair the material to glue the main factor of attach sex, strength, heat stability, the water steady, the low temperature work an etc. and put forward on this foundation cold repair the research development outlook that the asphalt admixture anticipate.
