The indirect tensile test can be used to establish the structural properties of asphalt mixtures. Existing indirect tension test devices have several problems that can affect the accuracy and repeatability of test results. Because of these problems, a new indirect tension test device, developed by Michigan State University and further modified by Louisiana Transportation Research Center (LTRC), was fabricated locally and used to reduce the test variability. The variation between several structural properties was investigated for specimens tested in two different indirect tension test devices--the current LTRC test device and the Louisiana modified device--within the parameters of mixture type, asphalt cement source, and compaction effort. Mechanical tests conducted were the indirect tensile strength test, the diametral resilient modulus test, and the indirect tensile creep test. The results of the test program indicated that the mechanical properties measured with the modified test device were significantly different from those measured with the existing test device; the modified test device can capture the temperature effect on the resilient modulus better than the existing test device; and resilient modulus and Poisson's ratio were significantly different between mixture types.
