| 摘要： | Pavement distress is an important indicator of pavement performance. The Long-Term Pavement Performance (LTPP) program has been collecting distress information on more than 2,000 test sections located across North America since 1989. However, these surveys were performed using three different methodologies-two photographic and one manual. Additionally, over the years, distress definitions and measurement techniques were revised in an attempt to improve consistency in data collection. The primary objective of the research reported here was to produce a comprehensive consolidated distress data set to reconcile differences between data collected using these different methodologies. |
