A STUDY ABOUT THE USE OF MEASUREMENT DATA BY THE HIGH-SPEED ROAD SURFACE MEASUREMENT VEHICLE

In Japan, road surface quality of expressways such as rutting, cracking and roughness is measured with a high-speed road surface measurement vehicle capable of performing measurements while operating at a speed of 80 to 100 km/h. It has been found that since the measurement technology used for the measurement vehicle enables high accuracy measurement, it can be used to: (1) determine high inspection priority sites, which can be achieved through IRI-based screening of roughness problem sites; (2) measure steps due to damage to bridge bearings, concrete slabs or other components; and (3) detect damage or other anomalies at bridge joints. Thus, the technology can be used to develop methods for detecting damage or anomalies of the road structure inexpensively and efficiently. This paper outlines the Pavemeter, a road surface measurement vehicle, and reports on a method of systematic road maintenance using the vehicle.
