A system that supports road surface property measurement vehicles at a maximum speed of 100 km / h and supports maintenance and improvement design of Expressway pavements.
A uniquely developed high-speed road surface property measurement vehicle capable of measuring roads at 100km / h. It can measure rutting, cracking, and flatness (σ 3m, IRI) at speeds up to 100km / h, and can use GPS and gyro technology to measure the road's cross-section, and use non-contact measurement to ensure smooth and safe Measurement is possible even while a general vehicle is running.
Features
- Improvement point extraction support system
Evaluate the soundness of the road surface by rutting, cracking, flatness (σ3m or IRI) alone, or the combination of MCI, etc., and select the pavement improvement priority points.
In addition, it is possible to evaluate the amount of steps using a road profile for IRI calculation, and to find planar damage and abnormal spots using a crack measurement system.
- Longitudinal crossing correction design support system
Kinematic GPS measurement technology accurately and speedily measures the cross-sectional shape of the road surface, and provides information that leads to "accident measures", "riding comfort measures", "roadside environmental measures", and "disaster prediction". Based on these results, we will perform "improved design (correction design for vertical crossing)" of the existing road surface and support "calculation of improved business volume".
