青川岩沥青改性沥青及其混合料技术性能研究
Research on the Performance of Qingchuan Rock Asphalt Modified Asphalt Binder and Its Mixture
摘要
Abstract
In order to research the influence of Qingchuan rock asphalt on the performance of asphalt binder and its mixture,the dynamic shear rheometer test and bending beam rheometer test were carried out on rock asphalt modified asphalt binder with the concentration 6%,8% and 10% and control asphalt binder,and thereby to determine the optimal concentration of Qingchuan rock asphalt.Based on this,rock asphalt modified mixture at the optimal concentration and control asphalt mixture were subjected to pavement performance tests.The results showed that the comprehensive performance of rock asphalt modified mixture was the best when the concentration was 8%;rock asphalt could significantly improve the high temperature performance and water stability performance of asphalt mixture.However,for the effect on low temperature performance,it was necessary to carry out further tests to study.关键词
