The result of road surface profiler is almost continuous data. The road surface profiler generates far more data than the normal rut bar with 3, 5, or even 10 sensors. The road surface profiler can generate indicator statistics for an operator defined interval. The economic practicability of this technology is more reflected in the data obtained can be used to calculate Ride comfort indicators.

First of all, for the use of the heavy weight deflectometer, take the detection of bridge deflection as an example: install the heavy weight deflectometer on the detector bracket and place it in contact with the measured point on the bridge.

The calibration of the universal testing machine needs to verify the accuracy of the system instruments responsible for obtaining force and displacement measurements.
