Problems solved by technology

[0005] The object of the present invention is to provide a colored permeable pavement material and its preparation process to solve the problem of the aggregate being compressed during the use of the permeable pavement in the prior art. The color of the pavement gradually becomes lighter over time until it shows the color of the aggregate due to broken, thin and easy-to-wear pavement color layers. Improve the color stability of the permeable pavement, improve the service life of the permeable pavement, maintain the color of the pavement for a long time, and increase The purpose of the functionality and aesthetics of the pavement, while further enhancing the overall compressive strength of the permeable pavement

Embodiment 1

[0051] Clean and crush the crushed stone aggregates and air-dry the crushed stone aggregates, heat to remove the moisture on the surface of the crushed stone aggregates and in the gaps, so that the crushed stone aggregates are heated and expand, and stir the expanded crushed stone aggregates at a constant temperature material, while spraying an impregnating agent to the crushed stone aggregate, the spraying amount of the impregnating agent is greater than the impregnating dose required to cover the surface and gaps of the crushed stone aggregate, and then drying to obtain colored crushed stone aggregate;

[0052] Mix the colored crushed stone aggregate, slag, expanded vermiculite, and fly ash, add water and stir to obtain the first mixture; mix the adhesive, reinforcing agent, and water reducing agent, add water and stir to obtain the second mixture, and mix The first mixture and the second mixture are stirred to obtain the colored water-permeable pavement material C1;

Abstract

The invention discloses a colored permeable pavement material and a preparation process thereof. The pavement material comprises the following raw materials in parts by weight: 500-600 parts of colored crushed stone aggregate, 5-25 parts of slag, 5-25 parts of expanded vermiculite, 10-30 parts of fly ash, 150-250 parts of an adhesive, 10-25 parts of a reinforcing agent, 10-15 parts of a water reducing agent and 150-200 parts of water, wherein the colored crushed stone aggregate is crushed stone aggregate with the surface and gaps filled with an impregnant. According to the permeable pavement material disclosed by the invention, after the crushed stone aggregate is treated by the impregnant, compared with a traditional manner of spraying the crushed stone aggregate on the surface of a pavement after completion of pavement construction, the impregnant plays a role in protection and reinforcement, and can be used as a protective layer to improve the wear resistance of the crushed stone aggregate; and moreover, the compressive strength of the aggregate can be further enhanced by filling of the gaps of the aggregate, so the colored crushed stone aggregate is not easy to crush and fade, the compressive capacity of the pavement can be improved, the color of the pavement can be kept more enduringly, and the functionality and attractiveness of the pavement are maintained.

Description

technical field [0001] The invention relates to the field of pavement materials, in particular to a colored permeable pavement material and a preparation process thereof. Background technique [0002] The permeable pavement is a pavement made of air permeable concrete with large porosity, which is made of aggregates with large particle size or uniform particle size and cement mineral admixtures and other cementing materials. Permeable pavement can allow rainwater to flow into the ground, effectively replenish groundwater, and alleviate some urban environmental problems such as the sharp drop in urban groundwater levels. It is an excellent pavement material for maintaining ecological balance and alleviating the urban heat island effect, and is the best material for building a "sponge city" . [0003] In order to improve the compressive strength and water permeability of permeable pavement materials, patent CN109653054A discloses a permeable concrete ground structure, the per...
