The Study of Curing Characteristics of Epoxy Asphalt

Abstract:

Epoxy asphalt has been proposed for the steel bridge deck and the heavy traffic on the road because it shows excellent heat resistance, free from bleeding, low temperature cracking resistance. In this paper, the curing characteristics of epoxy resin system and epoxy asphalt system were studied. The curing time and the viscosity of different epoxy resin and epoxy asphalt systems were tested. Experimental results indicated that: In the pure epoxy system, the curing time was decreased with the content of curing agent and accelerator increasing, and increased with the diluents addition. Epoxy asphalt was prepared after asphalt system addition; the viscosity was increased with curing time increasing and accelerator content increase. The allowable reserved time was decreased with the accelerator content increase. The growth of the system viscosity was slowly and the curing of epoxy asphalt was hindered with the more asphalt addition.
