| 摘 要： | 通过室内环道试验，对半刚性基层沥青路面基层、底基层材料的疲劳衰减规律进行了深入研究，研究表明底基层为半刚性路面的临界荷位与半刚性材料的应变疲劳规律取决于其应变状态，通过实测应变与理论应变的对比分析，认为各层应变值与用抗压回弹模量的计算应变值较吻合，建议在弯沉和弯拉应力（应变）验算时统一采用抗压回弹模量。

| Abstract: | Through circular road test,the fatigue properties of the semi-rigid base and subbase materi-als are studied in labUratury.The test results show that the critical layer of semi-rigid pavement is thesubbase layer and the fatigue law is determined by the strain level of subbase layer.The tested strainsof each bottom layer are curresponding to the theoretical strains which are calculated by programCHEVRON by using modul of cumpression resilience. |

| Keywords: | semi-rigid pavement strain fatigue modul of compression resilience |
