| 摘 要： | 结合我国目前沥青路面常用的结构型式,选取LSAM-25、Superpave25、ATB-25三种级配类型,采用矩形梁四点弯曲疲劳试验作为沥青混合料疲劳性能研究的标准试验,通过对3种沥青混合料疲劳性能的分析,确定沥青胶结料的材料性质是影响混合料抗疲劳寿命的最主要因素,但在较大应力比时,混合料结构抗力的作用更为凸显和关键。

| Abstract: | The paper analyzed the fatigue performance of three kinds of asphalt mixture, determined the most important factor of influencing the anti-fatigue life of the mixture was the material properties of asphalt binder. However, under the condition of the greater stress ratio, the structural resistance of mixture was more prominent and crucial. |
