Title: FIELD AND LABORATORY INVESTIGATION OF STRIPPING IN ASPHALT PAVEMENTS: STATE OF THE ART REPORT
Accession Number: 00676634
Record Type: Component
Availability: Find a library where document is available Abstract: Stripping of hot mix asphalt (HMA) pavements appears to have become a major problem in recent years. More and more states are specifying the use of antistripping agents. There is a need to investigate and identify the problem properly so that decisions are not made solely on the basis of observation of isolated distress areas. External factors and in-place properties of HMA pavements can induce their premature stripping. Contributing factors, such as inadequate pavement drainage, inadequate compaction of HMA pavement, excessive dust coating on aggregate, inadequate drying of aggregate, and overlays on concrete pavements, are described. Suggestions for alleviating the problems associated with these factors are given, and an investigative methodology based on forensic experience is recommended for use by the specifying agencies and industry that want to establish whether stripping is a problem either on a specific project or statewide. Current practices of using laboratory moisture susceptibility tests across the United States are reviewed and the AASHTO T283 (Modified Lottman) test method is recommended for use until more suitable and reliable tests are developed and validated.
