摘要: The Strategic Highway Research Program's efforts to monitor surface distress on the test sections under the Long Term Pavement Performance (LTPP) research is described. To achieve its objectives, SHRP is making use of the photographic distress survey technology which provides for high resolution 35 mm black and white photographs and photographic transverse profile measurements. Manual distress surveys are used as a backup data collection method. By definition, the latter cannot have the detail and consistency of the photographic survey, and will be rater-dependent. An accreditation process has therefore been established by SHRP to provide a means of ensuring the quality and consistency of distress data collected for the LTPP program by regional coordination office raters. This report describes the accreditation process and its implementation to date including its basis, components, and grading system. Two workshops conducted by SHRP are also described. Recommendations are made for improving the overall process and its implementation.
