摘要
本文通过20多种结构的半刚性基层沥青路面的落锤式弯沉仪(FWD)与贝克曼梁(BB)定点弯沉测试,探讨了两种不同性质的弯沉仪之间的相互关系。由测试结果发现这两种弯沉仪的实测弯沉值差别不大,具有良好的相关关系。对应用FWD评价半刚性路面结构性能具有重要意义。
Through a lot of comparative deflection tests between fallingweight deflectometer(FWD) and Benkelman beam (BB) on more than 20kinds of typical semi-rigid pavements, the correlation between the two devicewas investigated. It was found that the deflection values measured respecti-vely by FWD and BB were in good regressive relationship. It is useful to useFWD for evaluating the semi-rigid pavements.
