Evaluation of Ideal-RT, HT-ADT and Additives on Bituminous Mixture Performance

Kentucky Transportation Cabinet (KYTC) wants to determine if either Ideal-RT or High-Temperature Indirect Tensile Strength (HT-IDT) can be used in lieu of Hamburg testing. Both forms of testing require less time to perform, confer significant cost savings in terms of equipment, and demand less laboratory space. Because additional additives (e.g., anti-stripping, rejuvenators) can be used during the production of bituminous mixtures, the Cabinet needs to evaluate if their use could affect Ideal-CT results and mixture performance.
