Predicting Moisture-Induced Damage to Asphaltic Concrete - Field Evaluation
A laboratory test method for the prediction of moisture damage in dense graded asphaltic concrete mixtures was developed in the Phase I study of NCHRP Project 4-8(3) and is described in NCHRP Report 192. The method consists of obtaining ratios of tensile splitting strength and resilient modulus using compacted laboratory specimens subjected to vacuum saturation and to freeze-plus-warm-water-soak accelerated moisture conditioning. The ratios are used to predict short-term and long-term moisture-induced damage representative of field conditions. Results from the Phase II, 5-year field evaluation portion of the study, are presented in this report. The purpose of the study was to examine the predictive capabilities of the test method and to determine if the predictive ratios and observed stripping were reasonably representative of pavement conditions in the field. The test method appears to give reasonable predictive levels in the field and is sensitive to mixture variables.
