IMPLEMENTATION--PREDICTING MOISTURE INDUCED DAMAGE TO ASPHALTIC CONCRETE DESIGN MIXES

Six aggregate sources from around the State of Montana were selected to represent various qualities of aggregate and asphaltic concrete. Resilient ("R") Modulus tests, maximum tensile split tests and immersion compression tests were performed on each source and compared for correlation. Specimens used for the resilient modulus and the maximum tensile split tests were subjected to severe temperature conditioning, representing several years of natural exposure. The resultant data indicates that the use of the maximum tensile split tests and the "R" modulus test are not appropriate for use on a routine basis. The Montana Department will continue to use the immersion compression test for moisture susceptibility prediction. (FHWA)
