摘　　要：应用FWD和自动弯沉仪,以动态弯沉和反算模量平均值为指标实测了两个路面状况不同的段落,结果表明,路面状况与动态弯沉、反算模量关系密切;采用固定路基模量反算比改变路基模量反算时的路面状况差异更显著,并且此种差异与动态弯沉有较好的一致性,可采用FWD准确评价路面状况。The dynamic deflection and mean back-calculation modulus for pavement states are detected using FWD and automatic deflectometer. two sections of road with different The results indicate that pavement states have a close relationship with dynamic deflection as well as back-calculation modulus; the difference of pavement states is more obvious when applying fixed back-calculation modulus, which is consistent with the dynamic deflection, so the FWD can accurately evaluate the pavement state
