Proposed methods of test designed to measure the resistance of bituminous paving mixtures to the deleterious effects of water have varied from basic measurements of interfacial tension to simulated traffic tests. Deficiencies associated with artificial coating and curing conditions, artificial water exposure, exposure conditions for accelerated action, etc., are common to many of the tests reviewed. Methods for which correlation with road service is claimed require special equipment not normally found in highway and material laboratories. There remains, then, the need for a small-scale laboratory test of a quantitative nature which can be correlated with actual field performance.
