摘　　要：采用美国工程兵旋转压实剪切试验——GTM(Gyratory Testing Machine)与马歇尔试验方法对同一标段AC-20C沥青混合料目标配合比进行设计,通过对2种试验方法高温稳定性的对比分析,得知采用GTM设计方法,可使沥青路面密度高、空隙率小、沥青用量少,具有优良的高温稳定性,有效降低车辙路面常见病害,延长路面使用寿命。The same bid section AC-20 C is made asphalt mixture target mixture ratio design by means of GTM(Gyratory Testing Machine) research and Marshall test method. Through a comparative analysis on the high temperature stability of the two methods, it is concluded that the GTM design method of excellent high temperature stability will lead to the high density of asphalt pavement, small void fraction and less dosage of asphalt, which can effectively reduce rutting pavement common diseases and prolong the service life of pavement.
