The Hawkeye 2000 Transverse Profile & Rutting (TPR) System records transverse profile and rut depth information using spread laser technology. A pair of spread lasers is mounted on the rear of the survey vehicle to generate over 1200 measurement points across a 4m wide path, thus reducing the effects of vehicle position in lane.
An integral camera with each laser is used to measure the deviation between the pavement and a projected straight edge. The TPR system is used in combination with high resolution point lasers to also measure longitudinal profile, roughness and macro-texture.
Applications:
- Network level rutting at highway speeds
- Baseline surveys
- Contract validation
