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-B is specialized to test IRI;

Besides IRI, RSP 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).

Features:

1. Modular system, easy for maintenance;

2. Real-time data collection for IRI, σ, RN, RQI, SMTD/MPD, RUT, speed etc.

3. Testing at traffic speed enables faster measuring and saving time;

4. Real time graph display;

5. Adopts imported sensor and accelerometer

6. Cover lane width of 3500mm

7. Accords to ASTM E950 Class 1 profiling;

8. Adapt to third party analysis software such as ProVal

9. With GPS built-in, get coordinate in real time(for model TBTPQL-A/D/F)

10.With DMI installed on rear wheel, easy for surveying the distance;

11. Laser sensor can be extended up to 17pcs and min. to 7pcs;
