Evaluation on bearing capacity of pavement structure

Abstract：The static deflection value measured by Benkelman Beam are compared to the pulse dynamic deflection value measured by Dynatest 8000 FWD drop hammer.Calibrating relationships between them and the values of specification are established.The evaluating system for performance of pavement is established from high type pavement.And grade standards are determined.
