Problems solved by technology

In addition, due to the large void characteristics of drainage asphalt concrete, it is more susceptible to sunlight, air and water erosion, resulting in reduced durability of the mixture, loss of water permeable function, and deformation of permeable bricks. Modified asphalt with high viscosity and high softening point must be selected. Binder

Embodiment 1

[0026] 1) Put 85Kg of 90# asphalt heated to 165°C into the mixer, then add 8kg of styrene-butadiene-styrene block copolymer and 7kg of polypropylene to stir while raising the temperature to 180-190°C and stir for 2 Hours or more to make high viscosity (high softening point) modified asphalt;

[0028]

[0029] 2) Mix the crushed stone with a particle size of 5-15mm and the crushed stone with a particle size of 3-<5mm at 170°C with mineral powder to form a mineral mixture, and the weight ratio of the three is 10:4:1; Add 960Kg of the above-mentioned mineral mixture into the mixing tank of the mixer, dry mix for 5-10 seconds, then add step 1) 40Kg of high-viscosity (high softening point) modified asphalt and mix with the mineral mixture for 15-20 seconds to obtain water permeability Permeable asphalt mix for brick subfloor;

[0030] 3) Take 10.35Kg of the permeable asphalt mixture in step 2) and put it into a 300×300×60mm mold f...

Embodiment 2

[0034] Steps 1), 2), and 3) are the same as steps 1), 2), and 3) in Example 1;

[0035] 4) Mix 9.8Kg of resin 196 with 0.05Kg of cobalt naphthenate and 0.15Kg of methyl ethyl ketone peroxide to make a cement and mix with 190Kg of colored stones to form a colored stone mixture;

[0036] 5) Take the 1.9Kg colored stone mixture from step 4) and put it into the permeable asphalt concrete in step 3), move it to the plane of the mold frame and move it to the forming machine for molding, and demould after 3 hours.

Embodiment 3

[0038] Steps 1), 2), and 3) are the same as steps 1), 2), and 3) in Example 1;

[0039] 4) Mix 9.6Kg of resin 196, 0.2Kg of cobalt naphthenate, and 0.2Kg of methyl ethyl ketone peroxide to make a cement and mix with 133Kg of colored stones to form a colored stone mixture;

[0040] 5) Take the 1.62Kg colored stone mixture from step 4) and put it into the asphalt concrete in step 3), move it to the plane of the mold frame and move it to the forming machine for molding, and demould after 3 hours.

[0041] Selection of permeable brick application occasions:

[0042] 1. Choose permeable bricks with different product specifications and water seepage coefficients according to different uses of the road.

[0043] The use of pedestrian streets: products with specifications of 300×300㎜ or 300×150㎜ should be selected, because the surface of permeable bricks is relatively rough, and products with too small specifications will affect the aesthetic effect of the overall pavement. The thic...

Abstract

The invention discloses a coloured asphalt concrete permeable brick and a preparation method thereof. The preparation method comprises the following steps: for a bottom layer, stirring an open-graded drainage type wearing layer mine material mixture and high-viscosity modified asphalt in a mixer to prepare a permeable asphalt mixture; then, filling a mould with the permeable asphalt mixture according to a specified amount, compacting, and preparing permeable asphalt concrete; mixing required coloured stone, unsaturated resin, an accelerator and a curing agent to prepare a coloured surface layer mixture; adding the coloured surface layer mixture to the bottom layer permeable asphalt mixture to the plane of a mould frame, moving the mould to a brick pressing machine for moulding, and de-moulding after three hours to obtain a coloured asphalt concrete permeable square brick. The road surfaces which are paved by the coloured asphalt concrete permeable bricks have the characteristics that the water permeability is high, the bearing capacity is high, and a very good walking comfort feel is given to people by flexible bottom layers. The city is beautified; the drainage and underground water storage capacity of an urban road are enhanced; positive effects on regulating the weather of the city and keeping ecological balance are achieved.

Description

technical field [0001] The invention belongs to the technical field of road pavement materials, and in particular relates to a colored asphalt concrete permeable brick and a preparation method thereof. Background technique [0002] Permeable bricks originated in the Netherlands. The Dutch made a small pavement brick and laid it on the road surface in order not to sink the ground of the city built by the sea, and reserved a gap of 2 mm between the bricks so that the rainwater will be absorbed when it rains. It will seep into the ground through the gaps between bricks. Later, the United States invented pavement bricks with a strong water absorption function. When the brick itself is full of water, it will drain to the ground, but the drainage speed is very slow. This kind of brick is not suitable for rainy weather. In the 1990s, my country invented a pavement brick that is full of permeable holes and has good water permeability. Rainwater will quickly flow underground from th...
