This paper summarizes the findings of a six-year study of moisture damage of asphalt mixtures, which was conducted at The University of Texas at Austin. The objectives of the study were to define the nature and severity of moisture damage in asphalt pavement mixtures, develop techniques to identify mixtures that are moisture susceptible, and develop recommendations to eliminate or minimize the problem. While this study has primarily focused on problems and mixtures in Texas, additional mixtures and experience from other areas in North America were considered. The study involved laboratory investigations, including the evaluation of mixtures subsequently used in construction, a field evaluation of methods of treating asphalt mixtures with hydrated lime, and an evaluation of actual pavement mixtures that exhibited moisture damage.

This report summarized the results of field evaluation of the effectiveness of lime and various antistripping additives using the following methods: (a) Modified Lottman Method (Tex-531-C) and (b) Boiling Test (Tex-530-C). Core samples were obtained from the field test sections up to 48 months after construction. Field data to date show very little evidence of distress which is directly related to moisture damage or stripping. This was anticipated due to the slow rate of moisture ingress under adequate construction compaction.

This research project utilized laboratory evaluations to study effects of freeze-thaw cycling on the tensile strength of eight Hot Mix Asphalt mixtures and to determine if the Georgia Loaded Wheel Tester could be utilized to measure moisture susceptibility of Hot Mix Asphalt mixtures. The evaluation involved eight Hot Mix Asphalt mixtures from combinations of two aggregate types and four asphalt-additive-aging possibilities. Laboratory testing was accomplished in the first phase with the production of 2.5 by 4 inch cores that were freeze-thaw cycled and tested for their indirect tensile strength following Wyoming modified AASHTO T283. The second phase was accomplished using 3 by 6 inch cores that were conditioned and tested for rutting using the Georgia Loaded Wheel Tester. Finally, a statistical analysis was performed to determine if performance of the various mixtures was significantly different in groups of asphalt types and to determine if the Georgia Loaded Wheel Tester was a viable measurement tool for moisture susceptibility.

This report summarizes the results of determining the moisture susceptibility by the primary test methods: (a) Original Lottman Method. (b) Modified Lottman Method (Tex-531-C); (c) Tunniclif f-Root Method; and (d) Boiling Test (Tex-530-C). Comparisons were made between the laboratory mixtures, plant mixtures, and cores obtained from the field test sections to determine the effectiveness of the various antistripping additives and to evaluate the various methods for measuring that effectiveness.
