Abstract

The Roads and Traffic Authority of NSW (RTA) in partnership with the CSIRO has developed vehicle mounted technology (RoadCrack) to automate the detection and classification of cracking in road pavements. It will improve the quality and reliability of data and reduce collection costs. RoadCrack detects cracks (greater than 1 mm width) and classifies them as transverse, longitudinal or crocodile (fatigue) while operating at highway speeds (greater than 80 km/hr), irrespective of the surface type (sprayed seal, asphalt or concrete). It samples at 2 metres in 10 metres (20 percent) longitudinally, for a detection width of 750 mm in the outer wheel path. Analysis of data is executed in "real time". RoadCrack is a cost effective procedure for collecting reliable cracking data for roads. This readily available data will provide more effective management for road maintenance. The RTA will complete a survey of about 20,000 kilometres of its road network by 30 June 1998. (A)
