TechBrief: Key Findings From LTPP Distress Data
Primary Topic: Pavement Maintenance
Description: Consistent, accurate, high-quality pavement distress data are essential to all aspects of pavement engineering. Network-level pavement management systems require accurate distress data to support sound conclusions as to where and when to invest highway maintenance, rehabilitation, and construction dollars. At the project level, distress data are essential to correctly diagnose the causes of pavement deterioration, and thus the selection of the most appropriate remedial measures. In pavement research, these data are critical independent variables in the development of structural design methods and performance prediction models for both new and rehabilitated pavements.
