ABSTRACT
Highway cons仃ucfion has been increasing rapidly for recent development of highway construct needs corresponding improvement of pavement bearing capacity evaluation technique and deflection examination and analysis are the basis of pavement bearing capacity evaluation and the important ingredient of pavement service performance in order to adapt for the quick development,we need a ldnd of deflection examination equipment which is more exact,more efficient and hold more data,then accordingly a new analysis method for pavement bearing presence of Falling Weight Deflectmeter(HWD)meets this need.
However,it only has been more than ten years since we introduced HWD into our country, SO in onr country the application of HWD is not widespread and experiment criterion is very ordertopromotepopularization and applicationofHWD,flintandforemostthepaper
