| 摘 要： | 由于旧路面板与应力吸收层材料性质存在很大差异,层间粘层油种类及其用量大小、垂直荷载、温度条件等因素对其界面状态影响较大,利用课题组自行研制开发的LLM路面材料直剪试验仪进行室内模拟试验,并分析上述主要因素对应力吸收层与旧水泥路面板层间抗剪强度的影响。

| Abstract: | As material of old road slab and stress absorbing layer is very different from each other,interlayer bonding oil type and its content,vertical load and temperature have great influence on interface status.Indoor simulation test is performed with LLM pavement material direct shear tester independently developed by research group and the influence of above main factors on shear strength between stress absorbing layer and cement board interface is analyzed. |
