Technical Specification

Pavement roughness, as the main factor of dynamic loads which from vehicle movement, can expedite deterioration of pavement as well as wear and tear of vehicles. By using RSP, the pavement roughness can be determined as IRI.

TBTPQL with different modular can be used to measure other parameters of pavement, such as SMTD/MPD, RUT etc. which our model TBTPQL-A/C/D can do.

TBTPQL series Road Surface Profiler(RSP) adopts laser sensor and accelerometer combination to measuring the longitudinal profile; It's a real time, continuous measuring device for collecting data of pavement condition.

It's a real time continuous measuring device which installed in the front of vehicle, easy installation and operation;

TBTPQL Series Road Surface Profiler(RSP) can be equipped together with devices to realize the measurement for road damage such as crack detection(LCMS).

ASTM E950, ASTM E1926, ASTM 184, ASTM 1489, AASHTO R56
