Predicting moisture-induced damage to asphaltic concrete : field evaluation : final report.

7883510PDFTech Report82-R11.VirginiaVirginia Transportation Research CouncilMaupin, G. WVirginia Highway & Transportation Research CouncilUS Transportation CollectionVirginia was one of seven agencies that participated in the evaluation of a stripping test developed under National Cooperative Highway Research Program Project 4-8(3). The test was used to predict stripping of a field test section and the test results were compared to stripping that occurred in the test section over a 5-year period. The stripping test predicted that a significant amount of stripping would occur over a long time period. Strength tests and visual examination of field cores indicated a significant amount of stripping had occurred at 22 months; however, subsequent corings did not reveal significant additional stripping. Although considerable stripping has developed, the absence of pavement distress is believed to be related to a low traffic volume. Strength tests indicate that stripping is continuing; therefore, more time might be necessary to reach the predicted level of damage
