Pingdingshan's colored permeable concrete road construction materials and technology inquiries

Color-permeable paving features a high porosity in all layers of the ground, allowing precipitation to infiltrate through the entire surface layer. It not only complies with the application regulations for hard-surfaced ground but also possesses the ecological advantages of natural lawns and earth surfaces, enhancing soil permeability and aeration. This significantly reduces the runoff of rainwater, replenishes groundwater, and embodies a sustainable concept of coexistence with the ecosystem.

Honeycomb paving on municipal roads is predominantly composed of colored concrete surfaces. This is due to the ease and efficiency of colored concrete construction, its strength, load-bearing capacity, and long service life. With the construction and advancement of sponge cities, permeable concrete is increasingly demonstrating its status as the main force in urban construction.

The composition and mechanism of action of the material are as follows: permeable concrete material: water, cement, gravel, permeable concrete reinforcing agent, and surface protective agent. It participates in the cement hydration reaction to form a high polymer cement hydration body; significantly improves the compressive and bonding strength of the cement hydration body; enhances the concrete's frost-thaw resistance, durability, and weather resistance.

Color permeable paving is a landscape ground with a sturdy surface granule, ensuring good color, uniformity, and quality. Experts note that high-quality permeable paving can maintain its color and performance for up to 20 years, while its strength and durability can last for 50 years. Color permeable concrete paving also absorbs pollutants such as oil, carbon black, and rubber dust, maintaining a clean and aesthetically pleasing environment, and is easy to clean.

Permeable pavements boast superior permeability, allowing rainwater to seep quickly into the ground. As an underground entrance, they can alleviate the burden on surrounding drainage systems and prevent rainwater from flooding into the underground during rainy weather. The grading of coarse aggregates affects the void ratio of permeable concrete. Since permeable concrete contains no or only a small amount of fine aggregates, its structure is essentially a mass of coarse aggregates. The grading of the coarse aggregates directly determines its strength, making the study of the grading of coarse aggregates highly necessary. According to some previous research findings, the larger the particle size of the coarse aggregates, the higher the void ratio, and the stronger the strength of the permeable concrete it produces.
