摘要
Abstract
In this paper,the influence of epoxy agent content on the compatibility,crack resistance and tensile strength of epoxy asphalt was studied.The results show that the difference of softening points of upper and lower parts is basically unchanged under the condition of low epoxy resin content.When the content of epoxy resin is more than 40％,the difference of softening points of upper and lower parts of epoxy resin modified asphalt shows a sharply increased positive correlation with epoxy resin asphalt.On the whole,the elongation at break of epoxy resin asphalt is negatively correlated with the content of epoxy resin.The tensile strength of epoxy resin asphalt is positively correlated with the content of epoxy resin.Considering the difference of softening point,elongation at break,tensile strength and the evolution law of epoxy resin content,the optimal epoxy resin content in this study is 30％.关键词
