Designs of Automated Pavement Surface Distress Survey System

Résumé

This paper describes a novel design of survey system to collect pavement surface distress. The system includes four modules. They are artificial illumination module, image acquisition module, sync control module, data storage and analysis module. The system can carry out crack surveys at a nominal speed of 72km/h with full coverage of pavement surface. Crack recognition is performed offline. The prototype has been tested in laboratory conditions and completed a survey of about 15,000km real road at normal running speed (72km/h) between the year of 2003 and 2004.
