沥青路面基面层间接触状态对路面力学响应的影响分析

摘要

The mechanical response of the asphalt road surface under different contact conditions was calculated and analyzed by changing interlayer adhesion coefficient K.And analysis on the stress re-sponse by the changes of bonding condition between base and surface courses was made with the calcula-tion software BISAR.The interlayer contact state of different treatment measures was defined by determi-ning the value of K,based on the indoor direct shear test results.And the effect on pavement performance was analyzed.The interlayer contact state of field test between semi-rigid base and pavement surface is verified.%为了研究不同层间处治对路面粘结性能的影响，以层间粘结系数 K为指标通过 BISAR力学软件对不同接接触条件下的沥青路面层间应力进行了分析。通过室内基面层间剪切试验对层间不同处治措施下的粘结系数 K进行了界定，并根据定结果分析了层间处治对路面性能影响，计算了不同处治条件下了路面疲劳寿命。
