Experimental Study on Self-healing Tensile Resistance of Epoxy Asphalt
In order to make epoxy asphalt more widely used,the effects of different curing parameters and anhydride components on the fracture self-healing properties of epoxy asphalt were tested.The results show that with the increase of anhydride,the self-healing ability of epoxy as-phalt decreases,its tensile strain capacity decreases,and its tensile strength increases gradually.The longer the curing time,the stronger the tensile strength and tensile strain of epoxy asphalt.The self-healing ability of epoxy asphalt increases with the increase of curing temperature.Compared with the tensile strength,the tensile strain has stronger temperature sensitivity.
