By comparing the structural layers of selected test sections with the field tests, the effects of the Bending Depression (FWD) of the Bendman beam, the bearing plate and the dynamic deflection test equipment on the deflection test results were studied. The results show that there is a good linear correlation between the deflection data measured by the drop weight deflectometer and Beckmann beam and the bearing plate on each structural layer of the pavement. Under certain conditions Can be converted to each other.Compared with Beckmann beam, the deflection test results of falling weight deflection instrument has good repeatability and applicability.The results of this study provide the further popularization and application of drop-weight deflection instrument detection technology The technical basis
