Asphalt materials including binder, mortar, and mixture are extensively used in the field of pavement engineering due to their obvious viscoelastic properties. To study the phase-transition temperature () of asphalt materials, we apply dynamic mechanical analysis (DMA) to conduct several temperature-sweep mode tests and compare the values among these materials with similar sizes. Meanwhile, 27 AC5 mixtures are tested to determine the impact of binder type, gradation, and binder content on . Results indicate that the of binder and mortar is negative, but that of mixture is positive. Good correlations among of binder, mortar, and mixture with the same binder type are observed, showing that binder quality is the key factor affecting . Gradation type also affects , and the mixture with a finer gradation has a lower . Among the AC5 asphalt mixtures, the of AR mixture is lower than those of the others, thereby demonstrating better low-temperature performance.
