Abstract

The present invention relates to poured road surface laying material, and is especially one kind of poured epoxy asphalt concrete material with low construction temperature, high flowability and construction convenience and its preparation process. The poured epoxy asphalt concrete material consists of component A and component B in the weight ratio of 8-50 as well as stone material in the amount of 3-9 times the component A. The component A consists of asphalt 45-90 weight portions, epoxy resin 4.5-36 weight portions, modified alkylphenol 9-27 weight portions and glycidol ether 0-3 weight portions, and the component B is curing agent. The poured epoxy asphalt concrete material is prepared through mixing the materials of the component A, stirring at 120-160 deg.c, adding stone material, and final adding the heated curing agent and maintaining the temperature for 0-120 min.

Description

1. Technical field [0001] The invention relates to a novel pouring pavement material, in particular to an epoxy asphalt pouring concrete material and a preparation method thereof. 2. Background technology [0002] With the continuous growth of traffic volume and the obvious increase of axle load, as well as the channelization of high-grade highway traffic vehicles, asphalt concrete pavement is facing new severe challenges, especially the traditional continuous graded asphalt concrete pavement is challenged. Some highways have been damaged to varying degrees within one or two years of opening to traffic, seriously affecting the function and life of the road surface. This is because the viscoelastic properties of the asphalt pavement itself determine its inevitable shortcomings: (1) the thermoplasticity of the asphalt causes irreversible permanent deformation of the asphalt pavement, such as rutting, pushing, etc.; (2) the asphalt pavement is susceptible to natural deformation...
