Synthesis of Information Related to Highway Practices. Topic 52-07. Use of Pavement Data Collection Technology for Pavement Data Quality Management and MAP-21 Target Setting

Pavement data collection technology has been evolving over the past few decades, and increasingly so in recent years. High-precision, high-speed, automated equipment can collect more than 2,000 height measurements across a travelled lane and yield measurements of the pavement surface with sufficient frequency to extract transverse profile, longitudinal profile, cracking, and faulting. This provides important information to better pavement decision making. MAP-21, and successive federal legislation requires state departments of transportation (DOTs) to report pavement data at a 0.10-mile interval and establish pavement performance targets. Most, if not all, state transportation agencies have switched from manual pavement distress survey methods to automated/semi-automated pavement data collection methods in order to meet FHWA requirements. While these agencies gain more data, knowledge, and experience with automated/semi-automated pavement data collection methods, this migration also brings about new challenges. Those challenges include data quality control, data analysis, and decision making, in large part due to the rapidly evolving pavement data collection technology. The objective of this synthesis is to document the experiences, challenges, and state-of-the-practice solutions used by DOTs in the transition to automated/semi-automated pavement data collection processes and when establishing the associated MAP-21 pavement performance targets. Information gathered includes (but is not limited to): (1) The certification, verification, and audit process of evolving technology used by DOTs; (2) The compatibility of automated data with historical data; (3) The challenges in transitioning condition indices used in visual surveys when utilizing automated data; (4) Differences in reporting the distresses quantities due to issues from image quality, noise, or algorithms; and (5) Different levels of detailed distresses data used to establish pavement performance target. Information will be collected through literature review, a survey of DOTs, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.
