چکیده انگلیسی
In order to improve the performance of epoxy asphalt concrete (EAC), epoxy asphalt concrete modified with mineral fiber (FEAC) was designed. The properties of epoxy asphalt modified with mineral fiber (FEA) under different fiber contents and lengths were studied by viscosity test and direct tensile test, and the performance of FEAC with different fiber contents were evaluated through several laboratory experiments. The results showed that the mineral fiber with appropriate length and content can increase the viscosity of FEA, can improve tensile strength and fracture elongation of FEA, and can shorten the allowable construction time of FEAC. Moreover, the improvement effects of mineral fiber on permeability, friction and high temperature stability of FEAC is not significant, but use of mineral fiber can significantly increase raveling resistance and moisture susceptibility of FEAC. When the fiber content changes from 0% to 9%, the increasing amplitude of flexural strain at failure at â20 °C is 55.2%. It indicates that the addition of mineral fiber can significantly improve crack resistance of FEAC at low temperatures. Furthermore, FEAC has good resistance to fatigue cracking when fiber content is around 9%.
