Description
Epoxy asphalt mixture (EAM) is widely used in the pavement engineering recently. As a thermosetting material, its strength developing law is different from thermoplastic paving material such as HMA, which lead to a more complex construction control. This paper presents an experimental program on the strength developing law of EAM. Firstly, the viscosities of epoxy asphalt binder (EAB) in different temperatures were tested and the viscosity-time curve was constructed to investigate its developing law with time and temperature. Then the EAM strength developing law with reserved time and curing time in different temperatures were studied respectively using Marshall test from the view of phenomenology. Finally, some important time and temperature points of EAM construction control were concluded according to the researches and case studies were conducted to verify the effectiveness of the conclusion.
