| 摘 要： | 路面结构层的层间结合是影响路面整体结构强度的重要因素。通过对相同路面结构、不同层间的接触情况，运用BISAR3．0软件计算分析路面各结构层应力及路面寿命．可得出“当层间接触为光滑状态时，路面各结构层疲劳寿命将急剧降低”的结论。据此可知，良好的层间接触是提高路面使用寿命的重要因素。

| Abstract: | The combination of pavement structural layers is an important factor impacting the integral structure strength of pavement. Based on the contacts between layers of the same pavement structures, stress of each layer of pavement structures as well as service life of pavement is calculated and analyzed by BISAR3.0 software, thus the conclusion that the fatigue lives of all layers of pavement structure will fall rapidly when the contact between layers is smooth is deduced. Hereby, good contact between layers is... |
