Abstract
Based on the materials of old SBS modified asphalt mixture, the influences of compaction tem-perature on physical and mechanical properties of material regeneration performance under four normal RAP contents (20%, 40%, 70%, and 100%) and the mesures to improve performance of mixture un-der low compaction temperatures were investigated by laboratory tests. The results showed that, with the increase of compaction temperature, the regeneration performance of old SBS modified asphalt mixture was improved;with the increase of RAP ( Recycled Asphalt Pavement) , the required suitable compaction temperature increased, and the impacts of compaction temperature on compactness of mixture was more significant. It was suggested that the mesures of controlling RAP ( Recycled Asphalt Pavement) content, increasing coarse aggregate content appropriately and extending mixing time could be applicated to im-prove the performance of mixture, in order to achieve the same performance as compacting under a high compaction temperature and to meet the requirements of road.关键词
