【Abstract】 Many comparison experiments of pavement deflection by means of Benkelman Beam,Bearing Plane and Falling Weight Deflection (FWD) are carried out for each layer of a pavement, and the deflection linear relations between the three testing methods are presented for the pavement structures. Compared with Benkelman Beam, the testing results of Falling Weight Deflection possess more repetition and applicability. Based on the results, FWD can be applied to control the pavement quality during construction and maintenance by referring to the present testing standard.更多还原
