摘要
落锤式弯沉仪(FWD)是目前国内最先进的路面强度无损检测设备之一.本文依托于广清高速公路水泥硂路面养护工程,对目前流行的几种路面脱空检测方法进行横向对比。经过对比之后发现FWD设备在对路基顶面弯沉,板底脱空检测等多方面具有体积小、经济、快速、准确等优点,根据实际情况值得大力推广使用。
Falling Weight Deflectometer （ FWD） is currently one of the most advanced non-destructive testing equipment road strength. is article on the Guangzhou-Qingyuan expressway pavement maintenance engineering of cement Quan relied,Several of the popular off road horizontal space compared detection methods. After comparing FWD device was found after the top of the subgrade deflection,board at the end of cavity-detection,and many have a small,economical,fast,and accurate,according to the actual situation should be vigorously promote the use of.
