Distress identification manual for the long-term pavement performance project
Publication details: Washington DC Strategic Highway Research Program, 1993; SHRP-P-338, Description: 147 sSubject(s): Online resources: Bibl.nr: VTI P1411:338Location: Abstract: By using this manual, accurate, consistent, and repeatable distress evaluation surveys can be performed. Color photographs and drawings illustrate the distresses found in three basic pavement types: asphalt concrete-surfaced; jointed (plain and reinforced) portland cement concrete; and continuously reinforced concrete. Drawings of the distress types aid as a reference for severity assessment, and detailed instructions tell how to measure the distresses. Describes how to conduct the distress survey, from obtaining traffic control to measuring the cracks in the pavement. Sample forms are included for data collection. Appendices tell how to calibrate and operate profile and fault measurement devices.By using this manual, accurate, consistent, and repeatable distress evaluation surveys can be performed.
