摘要
采用传统贝克曼梁静态设备检测水泥混凝土路面存在检测效率低、参照系不稳定等缺点。结合浙江省某水泥混凝土路面检测项目,介绍了FWD设备在水泥混凝土路面基层顶面回弹模量、接缝传荷能力、板底脱空方面的检测方法。检测数据表明,FWD检测方法无损、高效,是水泥路面理想的检测设备。
The traditional benkelman beam is a static equipment in cement concrete pavement inspection with disadvantages of low detection efficiency and unstable reference system.Combined with a test project of cement concrete pavement in Zhejiang province,this paper introduces the test method of FWD in the aspects of resilient equivalent modulus at the surface of cement concrete pavement base,load-transfer efficiency of joint,and slab bottom void.The testing data shows that FWD is not only nondestructive and efficient,but also an ideal testing equipment for cement concrete pavement.
