Abstract
Epoxy asphalt binder is one kind of thermosetting asphalt binder composed by epoxy resin and asphalt mixed with curing agent in a certain temperature and a certain proportion. Relying on its excellent high temperature stability performance and strength characteristics, in recent years, epoxy asphalt has achieved successful application on many multi-span steel bridge deck pavement projects in China. In order to better grasp the functional characteristics such as drainage, noise reduction and anti-skid performance of open-graded epoxy asphalt mixture, this paper selects the epoxy asphalt as a cementing material to form OGFC4.75 and OGFC13 asphalt mixture. The permeable performance test, the pendulum test, the dynamic friction coefficient test and acoustic absorption coefficient test were applied to research the functional properties of epoxy asphalt mixture, the test results show that the larger size of OGFC gradation mixture has better permeability performance, then permeability performance of PG64 is slightly better than that of epoxy asphalt mixture. The pavement anti-skid performance of epoxy asphalt binder is better than that of PG64 asphalt binder. The acoustic absorption coefficient test shows that the epoxy asphalt can improve the noise reduction performance.
