The development of new laser technologies in recent years has changed pavement data collection, opening the door to a fully automated approach. In this paper the application of the Pavement Surface Cracking Metric (PSCM), inspired by the Universal Cracking Indicator proposed by William Paterson in 1994, and developed by the ASTM E17 group is presented. The method uses quantitative definitions to ensure consistency of the results and eliminate the subjectivity associated with human rating of the pavement distresses. Multiple runs of pavement data have been collected on three asphalt sections to assess the repeatability and reproducibility of the method. The Pavement Surface Cracking Index is also introduced to convert the PSCM value, which is a physical property of the pavement, into a 100-0 score of the pavement section. Finally, the use of the PSCM to classify the pavement distress and the inclusion of potholes and patching in the metrics are discussed.
