RAP掺量对冷再生沥青混合料的性能影响研究
Study on the Effect of RAP Content on the Performance of Cold Recycling Asphalt Mixture
摘要
Abstract
High-performance emulsified asphalt plant-mixed cold recycling technology is an economical and efficient way for pavement maintenance and reconstruction.To facilitate the high-content utilization of reclaimed asphalt mixture in the mid-dle and lower surface course of road pavements,the cold recycling asphalt mixture with reclaimed asphalt pavement(RAP)content of 0％,40％,60％,80％was designed.The influence of RAP content on the Marshall stability at 60℃,the splitting tensile strength at 15 ℃,the high temperature stability,the low temperature stability and water damage resistance were analyzed by the splitting strength test and Marshall test,etc.The results show that the indexes of cold recycling asphalt mixture with different RAP content meet the specification requirements,and it has enough strength,stiffness and sta-bility;tensile strength ratio(TSR)is greater than 80％,and it has good water damage resistance.The effect of cement dosage on the performance of cold recycling mixture was analyzed by standard Marshall test,the results show that the water damage re-sistance can be improved effectively by controlling the cement dosage in the range of 1％～3％.The research findings can pro-vide theoretical reference for the design and construction of cold recycling pavement.关键词
