摘要
采用落锤式弯沉仪(FWD)对广湛高速公路某段水泥路面主车道砼板的接缝传荷能力、板角脱空状况以及基层顶面当量回弹模量进行测试。结合路面破损情况的调查,分析了该段水泥砼路面破损的主要原因以及路面病害发展的规律。
Through the test of one speedway pavement regarding the A - road joint load - transfer capacity of the cement borad, void at slab and equivalent resilient modulus on the top of base by using Failing Weight Deflectormeter（FWD）, combining with the defect investigation of pavement damage, we found the main damage reasons of the concrete pavement and their relative developing laws. This has provided basic references for taking effective measures to control the defect and rehabilitate the structural and functional performance, so as to lengthen the road pavement service life.
