环氧树脂沥青混凝土增柔增韧技术研究

Study on Flexibility and Toughening Technology of Epoxy Resin Asphalt Concrete

通过添加橡胶粉对环氧树脂沥青混合料进行改性,采用低温弯曲试验、疲劳试验对改性环氧树脂沥青混合料进行试验。结果表明:掺量为2.1%的橡胶粉可以明显改善环氧树脂沥青混合料的柔性,对韧性的改善效果也较为明显,如需进一步提升环氧树脂沥青混合料的韧性,需继续研究环氧树脂沥青混合料的三维加筋技术。

This paper modifies epoxy resin asphalt mixture by adding rubber powder,and adopts low temperature bending test and fatigue test to modify the modified ring.The oxygen resin asphalt mixture was tested.The results show that rubber particles with 2.1%content can improve the flexibility of epoxy resin asphalt mixture,and the effect of improving the toughness is obvious.If the toughness of epoxy resin asphalt mixture needs to be further improved,the three-dimensional reinforcement technology of epoxy resin asphalt mixture needs to be further studied.
