摘要
为获取破损水泥混凝土路面(CCP)加铺半刚性基层沥青面层结构内部的工作信息,在试验路段施工过程中埋设传感器,监测温度、湿度和荷载多物理场作用下路面半刚性基层内应变及温度变化规律,得出了施工完毕运营初期和运营期间半刚性基层顶部和底部的应变变化情况。监测结果显示:基层的力学响应受旧水泥混凝土路面的影响较大,控制破损水泥混凝土路面加铺半刚性基层沥青面层反射裂缝的关键是保持旧水泥路面的稳定及半刚性基层的整体稳定性。
In order to obtain the inner work information of semi-rigid base asphah pavement overlaying on the damaged cement concrete pavement（ CCP）, the sensors were embedded in the test road during construction. And the strain and temprature vabiration of semi-rigid base under multiphysics, such as temperature, fluid and vehicle loads were monitored. The vibration of semi-rigid base at the beginning of and during the operation after completation were obtained. Based on the inspection results, it is known that the damaged cement concrete pavement has a very large influence on the mechanical response of base. Furthmore, keeping the stability old CCP and the integration of semi-rigid base is the key to control the reflective crack of semi-rigid base asphalt pavement on the damaged cement concrete pavement.
