ROAD MAP FOR MITIGATING NATIONAL MOISTURE SENSITIVITY CONCERNS IN HOT-MIX PAVEMENTS

One of the charges of the seminar on moisture sensitivity in hot-mix asphalt (HMA) pavements was to develop an outline for a road map for addressing the national concern of moisture sensitivity. That road map is presented in this paper. Implementation of the findings, best practices, and research needs presented in the road map are expected to be discussed by various materials and research committees within the transportation community. There cannot be a road map to address the national issues related to moisture sensitivity in HMA pavements without a vision, a mission, goals, and associated work tasks. Members of the national seminar steering committee have developed the following descriptions for these items: Vision - Eliminate moisture sensitivity distresses in HMA pavements; Mission - Provide the necessary tools to practitioners that can be used to eliminate moisture sensitivity in HMA pavements; and Tasks - Identify the best practices, gaps in knowledge, and research needs to address moisture sensitivity in HMA pavements.
