Description
The Falling Weight Deflectometer is used to determine the pavement bearing capacity. The hammer is lifted by hydraulic then fall freely, the impact force act on the platen then transfer to the pavement, thus to apply impulse to the pavement and result transient deformation, then the DAQ system obtains the signal and transmit to computer. It’s kind of advanced road testing equipment.
