Abstract The Superpave mix design system provides guidance in selecting the appropriate component materials for asphalt concrete mixtures. However, the selection of the design aggregate structure is left to the experience of the mix designer.Asphalt - University of Nevada, RenoUniaxial Thermal Stress and Strain Test (UTSST) The UTSST test method is used to determine the thermal viscoelastic and thermal volumetric properties of field cored or laboratory compacted asphalt mixtures under thermally induced loading conditions. This test has also been called the Modified Thermal Stress Restrained Specimen Test (M-TSRST)...National Center for Asphalt Technology - Auburn UniversityIn the early 1990s, a federal mandate required the use of rubber in asphalt mixtures; however, this mandate was later repealed and interest in the use of recycled tire rubber declined in most states. Some states, such as California, Arizona, Texas, and Florida, continued to use rubber modified asphalt technologies in many highway projects.
