Study on Low Temperature and High Temperature Performance of Epoxy Resin Particles Used for Asphalt Pavement
Abstract
In order to study the effect of epoxy resin particles on the low temperature performance and high temperature performance of asphalt mixture, the epoxy resin particles were prepared and the glass transition temperature of epoxy resin particles was measured. The bending test and rutting test were used to study the low temperature and high temperature performance of asphalt mixture mixed with and without the epoxy resin particles. The results show that the increasing of epoxy resin particles content is beneficial to enhance the thickness of the effective asphalt film. With the increasing of the epoxy resin particle content, the low temperature bending stiffness modulus of the asphalt mixture increased firstly and then decreased, while the dynamic stability reduced. It is indicating that the epoxy resin particles can significantly improve the low temperature cracking resistance of asphalt mixture, and is not conducive to the high temperature stability of asphalt mixture.
