Performance Evaluation of a Novel High Durability Epoxy Asphalt Concrete for Bridge Deck Pavements

Abstract:

A novel high durability epoxy asphalt concrete for bridge deck pavements is introduced in this paper, including the manufacturing process of epoxy asphalt binder and laboratory evaluation for this material. Various laboratory tests were conducted to evaluate the pavement performance of the materials, such as fatigue test, wheel tracking test, moisture susceptibility test and thermal stress restrained specimen test. Test results show that epoxy asphalt concrete has 20137 cycles/mm dynamic stability at 70°C, and-28.4 °C fracture temperature. The fatigue equations of epoxy asphalt concrete at different temperatures were obtained. Findings from the research indicate that the epoxy asphalt concrete is a suitable material for the pavement of long-span steel bridges in China due to its profound performance.
