This report summarizes research and development studies that were conducted within the past 20 years to compare hydrated lime and liquid antistrip additives on the moisture damage of hot mix asphalt (HMA) mixtures. A total of ten studies have been summarized in terms of their objective, materials used, experimental program, and the correlations of the measured properties to the long-term performance of HMA pavements. In most cases the correlations to the long-term performance have been estimated through mechanistic analyses of the HMA pavement using the engineering properties of the HMA mixtures that have been measured in the actual research studies. This report extends the applications of the research data from the experimental programs through the prediction of the long-term performance using up-to-date and sound pavement engineering principles.
