摘要
Abstract
In order to further improve the durability and road performance of slurry asphalt mixtures,a high viscosity and good stability modified emulsified asphalt-room temperature high viscosity modified asphalt-was devel-oped.The process of first modification and then emulsification was adopted,and the performance of high vis-cosity modified asphalt and before and after emulsified performance were analyzed and compared at different raw material dosages.It was determined that 8%SBS+2%viscosity enhancer was used for high viscosity modi-fied asphalt,and the optimal dosage of emulsifier B1 was 2.4%.The adhesion performance of high viscosity modified asphalt at room temperature and the wear resistance of mixed mixtures were further verified through pull-out tests and wet wheel wear tests,which far exceeded conventional modified emulsified asphalt.关键词
