PERMANENT DEFORMATION CHARACTERISTICS OF ASPHALT MIXTURES BY REPEATED-LOAD INDIRECT TENSILE TEST

This report reviews the basic concepts of the parmanent deformation structural subsystem, the properties required, and the possible methods required to obtain these properties. Special consideration is given to the permanent deformation parameters given by VESYS IIM. The results of this study suggest that the repeated-load indirect tensile test can be used to obtain the parmanent deformation characteristics or properties required for the structural design and analysis of pavements. It was also found that the permanent deformation behavior obtained using the repeated-load indirect tensile test is similar to that obtained using a triaxial test with an axial tensile stress.
