Experimental Study on the Low Temperature Performance of an Epoxy Asphalt Binder and Mixture

This paper presents an investigation into the low temperature performance of epoxy asphalt (EA) binder and mixture. The creep characteristics of EA binder at low temperature were determined by the bending beam rheometer test. The thermal stress restrained specimen test, bending strength test and bending creep test were utilized to characterize the low temperature performance and cracking resistance of EA mixture. Results showed that the low temperature grade of the EA binder is -16°C according to Superpave performance-graded binder specification. EA mixture exhibits approximately elastic behavior at temperatures below 0°C. The EA mixture shows much higher fracture strength and bending strength along with comparable fracture temperature compared to conventional asphalt mixtures.
