Problems solved by technology

Since the amount of colored cementitious materials in the three types of technology is relatively high, and the most expensive part of the colored pavement is the cementitious material, the cost of several colored pavements is relatively high
In addition, several types of colored pavements are water-sealed layers, which cannot store water, so they do not have the effect of alleviating urban heat islands
None of the published patents related to colored pavement materials have the functions of large voids, water permeability, and water storage

Embodiment Construction

[0016] The present invention will be specifically introduced below in conjunction with specific embodiments.

[0017] A colored self-leveling porous pavement surface material of the invention is mainly composed of cementing material and aggregate. The mass percent composition of the cement is as follows: 25-50% of epoxy resin, 10-30% of diluent, 30-50% of curing agent, and 15-40% of reinforcing material. The mass percentage composition of the reinforcing admixture is as follows: 10-30% of bentonite, 50-80% of talcum powder, 10-30% of 800-mesh quartz powder, and 10-30% of pigment. The aggregate is single grade limestone aggregate or gravel, and the particle size of the aggregate is between 9mm and 11mm. The ratio of single grade aggregate to cementitious material is 2.5:1~3.5:1. The epoxy resin is an oily epoxy resin, and the curing agent is a modified amine curing agent. The diluent is diethylene glycol glycidyl ether.

Abstract

The invention relates to a colorful self-leveling porous sidewalk surface material and a preparation method thereof, and belongs to the field of asphalt pavement materials. The colorful self-leveling porous sidewalk surface material comprises a cementing agent and aggregate. The colorful self-leveling porous sidewalk surface material is characterized in that the cementing agent consists of the following components in percentage by mass: 25-50% of epoxy resin, 2-5% of a diluent, 30-50% of a curing agent and 15-40% of a reinforcing admixture; the aggregate is single-grading limestone or gravel. Compared with the prior art, the colorful self-leveling porous sidewalk surface material has the beneficial effects: as the mixed material is prepared from single-grading aggregate, the amount of the cementing agent can be greatly reduced, and thus the manufacturing cost can be lowered. In addition, the colorful self-leveling porous sidewalk surface material has the property of large interspaces, can be used on a sidewalk pavement when being combined with a water-storage type substrate, rainfall storage can be achieved, and the urban heat island effect can be alleviated. The colorful self-leveling porous sidewalk surface material provided by the invention is good in high-temperature stability, good in low-temperature anti-cracking property, good in caking property, economic and environment-friendly, simple and easy to prepare, good in weather resistance and good in water permeation and storage.

Description

technical field [0001] The invention relates to a colored self-leveling porous pavement material for municipal sidewalks and a preparation method thereof, belonging to the field of asphalt pavement materials. Background technique [0002] In the past 20 years, my country's economy and society have developed rapidly, and people's living standards have improved year by year. Under the guidance of the national environment, urban residents have higher and higher requirements for living environment. As an important part of the city, roads should undertake more functions besides meeting the basic needs of traffic, such as the beautification of the city by colored roads, and the control of urban heat island effect by water storage on porous roads. [0003] The existing colored asphalt pavements in the market mainly include three categories: one is colored asphalt concrete; one is colored seal; the other is colored coating. Since the amount of colored binders in the three types of ...
