Abstract
The mixture material of Foamed asphalt cold-recycled has rapidly developed in our country and has gotten excellent practical effect .With the annual increase of heavy traffic and the influence of high temperature and rainy and other extreme weather , on the foamed asphalt cold-recycled pavement early built has appeared damage phenomenon ,especially rut , water damage .The heavy point of the research is how to confirm the gradation of milling planer material so as to make good use of the recycle material and enable its performance of the regeneration mixture material to reach the optimal .The experiment re-searched milling gradation and real gradation and conducted gradation design .Splitting strength and Mar-shall stability tests are conducted on the regenerated asphalt mixture material of two kinds of different screening methods.According to the result of experiment,the cold recycled technique of foamed asphalt should adopt real gradation to do the regeneration mixture design so as to improve the high temperature stability and to prevent water damage performance of recycled asphalt mixture .关键词
