The existing ASTM Method of Test for determining the Dynamic Modulus of an HMA (hot mix asphalt) mixture, this test is unknown to the operating departments of transportation (DOTs). Until this, "E* testing" was confined to research facilities. A substantial amount of hands on testing experience with E* will be required by DOT personnel before final acceptance of the concept can be accomplished. There is a need to evaluate a dynamic modulus test apparatus and appropriate test protocols in order that the E* test system will be accepted by DOTs as a method to characterize HAM mixes for design purposes. This study will establish a project advisory team, conduct a literature search, acquire equipment, establish a test matrix, perform E* tests, demonstrate the dynamic modulus test protocol, and prepare reports of findings.
