Abstract

The invention discloses epoxy asphalt concrete for roads and bridges and a preparation method thereof. The epoxy asphalt concrete for roads and bridges is prepared from the following raw materials byweight: 10%-20% of epoxy resin, 3%-6% of a curing agent, 20%-35% of aggregate, 25%-35% of a filler, 1%-5% of a coupling agent, 10%-20% of modified asphalt, 5%-10% of glass fibers and 5%-8% of water. According to the epoxy asphalt concrete for roads and bridges and the preparation method, through adding the epoxy resin and utilizing modified filtration, and by combining the filler components with different ratios and using the batch mixing process, the control is easily achieved, the mixing processing is conveniently performed, the texture uniformity is easily improved, the structural performance of the asphalt concrete can be effectively improved, aging deformation resistance is improved, the pavement laying effect is easily improved, and stability is easily improved, facilitating promotion and the use.

Description

technical field [0001] The invention relates to the technical field of asphalt concrete, in particular to epoxy asphalt concrete for roads and bridges and a preparation method thereof. Background technique [0002] In today's social life, the use of asphalt concrete is very common, which can pave the road surface and improve the quality, but for different road surface environments, the required asphalt concrete is also different. [0003] However, the performance of the existing asphalt concrete is poor, it is easy to be deformed, the structural stability is insufficient, the use effect is not ideal, and it is not conducive to the control of the process flow, so it needs to be improved. Contents of the invention [0004] The purpose of the present invention is in order to solve the shortcoming that exists in the prior art, and proposes a kind of epoxy asphalt concrete for road and bridge and preparation method thereof. [0005] In order to achieve the above object, the pr...
