摘要
Abstract
The gap gradingof rubber asphalt mixture is designed by mineral aggregatevoid volume filling method,and the gap grading rubber asphalt mixture is mixed from rubber asphalt.The dynamic stability,frozen-thaw and split residual strength ratio,residual stability ratio,and low temperature failure strain were determined for gap grading and dense-grading mixture,and road performance is analyzed for thegap grading rubber asphalt mixture.Besides,fatigue performance was tested for the mixture by four-point loading test to analyze the fatigue performance of the gap grading rubber asphalt mixture.The results show that the designed gap grading rubber asphalt mixture has a better low temperature performance,anti-fatigue property,high temperature stability and water stability than the dense-grading mixture.关键词
