摘要：	Phase 2 of Texas Department of Transportation (TxDOT) Research Project 0-6663: Evaluation of Pavement Rutting and Distress Measurements had the objective of evaluating the accuracy and precision of the new automated system developed by a TxDOT research group (composed of staff from the Construction Division’s Materials and Pavement Section) for the high-speed measurement of pavement surface distresses, texture, and cross slope. In addition, equipment vendors participated in the study by providing equipment that represents the state of the practice—the automated distress collection vehicle. This equipment is used by other state DOTs for visual distress data collection through either vendor contracts or direct purchase. The implementation of an automated distress measuring system will allow the assessment of the highway condition at both the network and project levels and potentially eliminate the need for manual visual assessments to rate pavement distresses for network-level Pavement Management Information System (PMIS) applications. Eliminating any subjective elements in visual rating leads to more consistent and reliable data. Consistent and reliable data on the Texas road network will enhance pavement management and, ultimately, allow better utilization of ever-decreasing funds and overall state resources.
