The evaluation of Hot Mix Asphalt moisture sensitivity has been developed into two categories; visual inspection test and mechanical test. However, most of them have been developed in pre-Superpave mix design. This thesis summarizes the new mechanical test for Superpave using the Nottingham Asphalt Test equipment (NAT). The mechanisms of Hot Mix Asphalt (HMA) moisture sensitivity are reviewed and the test protocols using the NAT are developed. Different type of mixes as moisture sensitive group and non-moisture sensitive group are used to evaluate the potential of proposed test. The test results are analyzed with two type of parameter based on performance character; retained flow number (RFN) and energy ratio (EE). Analysis based on energy ratio of elastic strain (ER[subscript EE]) at flow number of cohesion failure (FN[subscript C]) is more high potential to evaluate the HMA moisture sensitivity than other analysis. If removing the measurement error in data-acquisition process, analyses based on RFN at permanent deformation failure and cohesive failure also would have potential to evaluate the HMA moisture sensitivity. It can also verify that the vacuum pressure saturation used in AASHTO T 283 and proposed test have a risk to damage specimen before the load applying.
