Abstract

The invention belongs to the technical field of preparation of road materials and discloses an epoxy resin / cement mortar compound concrete material and a preparation method therefor. The epoxy resin / cement mortar compound concrete material is prepared through compounding a high-porosity epoxy resin gravel mixture and high-fluidity polymer modified cement mortar in a specific compounding manner that internal pores of the high-porosity epoxy resin gravel mixture are filled with the high-fluidity polymer modified cement mortar, and a dense compound structure is formed after the high-porosity epoxy resin gravel mixture and the high-fluidity polymer modified cement mortar are subjected to consolidation molding. The preparation method comprises the following steps: 1) preparing the high-porosityepoxy resin gravel mixture; 2) pouring the high-fluidity polymer modified cement mortar; and 3) performing concrete curing. Compared with the prior art, the epoxy resin / cement mortar compound concrete material has the advantages of high comprehensive performance, good stability and durability, high cost performance, convenience in construction, long construction cycle, and the like and is relatively applicable to the paving construction of semi-flexible pavements.

Description

technical field [0001] The invention belongs to the technical field of road material preparation, and in particular relates to an epoxy resin / cement mortar composite concrete material and a preparation method thereof. Background technique [0002] Asphalt concrete material and cement concrete material are two typical pavement materials for expressway construction in my country, each with its own advantages and disadvantages. Asphalt pavement is a flexible pavement with smooth road surface and comfortable driving, but its strength is low, its service life is short, and it is prone to high-temperature rutting and low-temperature cracking. The strength and rheological properties are greatly affected by temperature changes. When the temperature is high in summer, the asphalt material will weaken the cohesion between the aggregate particles due to the decrease in viscosity, which will reduce the strength and deformation resistance of the pavement, and it is easy to appear Waves,...
