Abstract

In 2006, the Ministry of Transportation of Ontario (MTO) completed a study with the Center for Pavement and Transportation Technology (CPATT) at the University of Waterloo to evaluate the performance of automated/semi-automated pavement distress data collection technologies. From this study it was recommended that MTO define concise guidelines with special attention to quality assurance for surveying pavement distresses at the network level using automated collection technologies and semi-automated distress analysis. In light of the above, the study detailed in this paper presents thedevelopment of pavement distress guidelines and a Distress Manifestation Index for Network Level (DMINL) evaluations using automated collection technologies and semi-automated distress analysis. To define and validate DMINL sections evaluated in the previous study were considered. The relative effect of each distress was obtained by linear regression and statistical analysis. The principle used to define weighing factors was that the distresses considered by the new guidelines should quantify with a minimum error the DMI estimated with MTO traditional method.
