| 摘 要： | 为分析旧水泥板沥青加铺层黑白层间水平剪切滑移和界面粘结两类失稳性破坏,通过复合结构弹性理论计算、MATLAB编程、层间剪切和拉拔试验,揭示了车速、路面附着系数、竖向荷载、层间接触系数、加载速率、温度、粘层油洒布量等对层间极值应力应变、剪切强度和拉拔强度的影响规律,分别建立了层间剪切强度与正应力、剪切速率、温度以及拉拔强度与拉拔速率、温度、粘层油洒布量的函数关系。分析结果表明:15℃时拉拔破坏界面发生概率从大到小排序为水泥板表面、粘结层、沥青膜,45℃时为粘结层、水泥板表面、沥青膜,层间平均粘结强度随着上述排序的递减而增大;为减少层间失稳性破坏,应适当提高行车速度,控制汽车轴载,清洁和糙化水泥板表面,选取适宜的粘层油洒布量,液体石油沥青为0.20～0.40L.m-2,乳化沥青为0.48～0.60L.m-2,并推荐以芯样平均拉拔强度和破坏界面位置作为加铺层施工质量检验判别依据。 |
