Abstract
To explore the differences in road performance between rubber modified asphalt mixture and traditional asphalt mixture,in this pa-per,70 base asphalt,SBS modified asphalt,and rubber modified asphalt were selected for comparative analysis of different asphalt mixture types(AC13,AC16 and AC20).The results show that the high and low temperature grade of rubber modified asphalt PG is improved by one grade compared with SBS modified asphalt.The low temperature grade of SBS modified asphalt PG is the same as that of No.70 matrix as-phalt,but the high temperature grade is improved by two grades.The water stability and low temperature performance of different types of as-phalt mixture are AC13<AC16<AC20,high temperature stability are AC20>AC16>AC13.Among them,rubber modified asphalt mixture has the best road performance.关键词
