Abstract

The invention provides asphalt-reclaimed water-permeable pavior bricks and a preparation method thereof and relates to the technical field of production of pavior bricks. Each pavior brick comprises a surface layer and a base layer, wherein the surface layer is prepared from the following raw materials in parts by weight: 30-40 parts of waste asphalt concrete, 20-28 parts of cement, 25-33 parts of sand, 5-10 parts of gravels, 4-6 parts of emulsified asphalt, 3-6 parts of mineral powder, 6-10 parts of glass fibers, 1.2-2.4 parts of polyvinyl acetate emulsion, 3-10 parts of clay, 0.8-1.6 parts of rubber powder, 5-10 parts of air entraining agent, 0.4-0.6 part of water reducer, 0.3-0.5 part of pigment powder and 1-3 parts of water; the base layer is prepared from the following raw materials in parts by weight: 30-35 parts of waste asphalt concrete, 22-24 parts of cement, 18-32 parts of sand, 17-23 parts of gravels and 2-3 parts of water. The preparation method comprises the following steps: (1) preparing surface layer ingredients; (2) preparing base layer ingredients; (3) carrying out molding, demolding, stacking and curing. According to the asphalt-reclaimed water-permeable pavior bricks and the preparation method thereof, the problems of the existing pavior bricks that recycling of waste cannot be achieved, the water permeability is poor, the volume weight is heavy, the skid resistance is poor, the compressive strength is low, the corrosion resistance is poor, and the shock resistance is poor are solved.

Description

technical field [0001] The invention belongs to the technical field of pavement brick production, and in particular relates to a permeable pavement brick for reuse of asphalt and a preparation method thereof. Background technique [0002] Pavement brick is a kind of paving material, which is mainly made of cement, stone and sand through processing, vibration and pressure or other molding processes, and is used for laying concrete pavement and ground engineering of urban road sidewalks, city squares, etc. Blocks, boards, etc., have a wide range of applications, and the consumption of daily materials is very large, so there is an urgent need to increase revenue and reduce expenditure. [0003] Every year in our country, the excavation and milling of asphalt mixture pavement materials due to the maintenance, repair and reconstruction of asphalt concrete pavement are huge in millions of tons, and it is also growing at a rate of about 15% per year. The production of this large a...
