路桥工程沥青混合料试验检测的有效方法

Effective Test Method of Asphalt Mixture in Road and Bridge Engineering

为了改善路桥工程沥青混合料的使用性能,本文提出把地聚合物作为一种新型沥青改性剂掺加到沥青混合料中,并通过试验检测的方式,对掺加地聚合物的沥青混合料的高温性能、水稳定性及低温性能进行评定,以优化沥青混合料,延长工程使用寿命。

In order to improve the service performance of asphalt mixture for road and bridge engineering,geo⁃polymer is proposed to be added to asphalt mixture as a new asphalt modifier,and the high-temperature perfor⁃mance,water stability and low-temperature performance of asphalt mixture mixed with geopolymer are evaluated through test,so as to improve the asphalt mixture and prolong the service life of the project.
