这是一种无损检测类检验路面质量的装置,是通过对路面施加冲击荷载,测定其弯沉值的装置,称之为落锤式弯沉仪(FWD)。落锤式弯沉仪分别对加载及相应的弯沉做定量的测定,对二个物理量分析以获 This is a non-destructive testing device to check the quality of the pavement. It is a device that measures the deflection by applying an impact load on the pavement, called a drop-weight deflectometer (FWD). Drop weight deflection instrument respectively, the load and the corresponding deflection to do a quantitative determination of the two physical quantities to get
