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 ratings of pavement distresses. Multiple runs of pavement data have been collected on three asphalt sections to assess the repeatability and reproducibility of the method. The application of the Pavement Surface Cracking Index 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 pavement distress and the inclusion of potholes and patching in the metrics are discussed.

近年来，新激光技术的发展改变了路面数据的收集，为全自动方法打开了大门。本文介绍了由威廉·帕特森（William Paterson）于1994年提出的通用裂化指示器并由ASTM E17小组开发的路面裂痕度量标准（PSCM）的应用。该方法使用定量定义来确保结果的一致性，并消除与人类对路面遇险等级的评估相关的主观性。已在三个沥青路段上收集了多次路面数据，以评估该方法的可重复性和可重复性。还介绍了使用路面表面开裂指数将路面的物理特性PSCM值转换为路面截面的100-0分数的应用。最后，
