沥青混合料配合比设计是沥青路面设计的重要环节,我国常用的马歇尔试验方法和路面实际受力状态和路用性能指标之间存在较大差异。美国旋转试验机GTM模拟了路面现场压实及汽车轮胎与路面的相互作用,依据力学分析原理进行沥青混合料配比设计,较之经验式的体积分析方法更为准确合理,所以GTM试验方法在我国的沥青混合料配比设计中得到越来越广泛的应用。 Asphalt mix design is an important part of asphalt pavement design. There is a big difference between the commonly used Marshall test method in our country and actual pavement condition and pavement performance index. The GTM of American Rotating Tester simulates the compaction of the road surface and the interaction between the tire and the road surface. According to the principle of mechanical analysis, the asphalt mixture proportioning design is more accurate and reasonable than the empirical volume analysis method. Therefore, the GTM test method China’s asphalt mixture ratio design has been more and more widely used.
