Application of The Pavement Surface Cracking Metric to Quantify Distresses from Digital Images

ABSTRACT
The advancement of new laser technologies in recent years has changed the resolution of pavement data captured during collection, creating the opportunity for a fully automated approach to condition evaluation. Inspired by the Universal Cracking Indicator proposed by William Paterson in 1994, and developed by the ASTM E17 working group, this paper will present the application of the Pavement Surface Cracking Metric (PSCM). By using quantitative definitions in order to ensure consistency of the results, this method removes the subjectivity that happens with human rating of pavement distresses. The repeatability and reproducibility of the method were assessed by collecting multiple runs of pavement data on three separate asphalt sections. The application of the Pavement Surface Cracking Index (PSCI) to convert the PSCM value, which is a physical property of the pavement, into a 100-0 score of the pavement section is also presented. Finally, the use of the PSCM to classify the pavement distress and the inclusion of potholes and patching in the metrics are also discussed.
