Sand-Based Pervious Concrete Pavement

Sand-Based Pervious Concrete Pavement, as a new member of the color permeable pavement family, is favored for its elegant, beautiful, and delicate appearance. Sand based pavement is made of silica sand as the main aggregate or surface layer aggregate, polymer organic binder as the main cementing material, and is made after a non-burning pavement and forming process, and has a water-permeable pavement.

As the world shifts towards more sustainable practices, the adoption of sand-based permeable concrete pavement emerges as a pivotal step in the right direction. Its innovative composition, coupled with its eco-friendly benefits, positions it as a top contender in the world of modern pavement solutions. By choosing this groundbreaking technology, urban planners and developers can lead the way in building a future where infrastructure and nature coexist harmoniously.

Exploring Sand-Based Pervious Concrete Pavement

Sand-based pervious concrete pavement represents a groundbreaking evolution in traditional concrete pavements. It harnesses the unique properties of permeable concrete combined with a composition that emphasizes sand as a primary aggregate. This innovative blend results in a pavement surface that is not only strong and durable but also allows water to pass through, effectively mitigating stormwater runoff and reducing urban flooding.

Environmental Advantages of Sand Based Pervious Concrete

1. Efficient Stormwater Management

One of the standout features of sand-based pervious concrete is its ability to manage stormwater effectively. Traditional impermeable surfaces lead to excessive runoff, contributing to urban flooding and soil erosion. In contrast, the porous nature of this pavement allows rainwater to infiltrate the ground naturally, replenishing groundwater tables and reducing the burden on stormwater systems.

2. Heat Island Mitigation

Urban heat islands, characterized by elevated temperatures in densely populated areas, can have detrimental effects on both the environment and human health. Sand-based pervious pavement plays a role in mitigating this phenomenon by absorbing less heat compared to traditional concrete surfaces. This results in cooler urban environments and contributes to energy savings by reducing the need for air conditioning.

Installation Process and Considerations

1. Base Preparation

The success of any pavement installation begins with meticulous base preparation. The site is cleared of debris, and the ground is graded to ensure proper water drainage. A well-prepared base provides the foundation for a durable and long-lasting pavement surface.

2. Mixing and Placement

The mixture for sand-based pervious concrete includes sand, cement, water, and minimal fines. This mixture is carefully proportioned to ensure optimal permeability while maintaining structural integrity. The concrete is then placed onto the prepared base and compacted, creating a uniform and sturdy surface.

3. Curing and Maintenance

Proper curing is essential to enhance the strength of the pavement. After installation, the pavement is covered with a curing compound and kept moist to allow for proper hydration of the concrete. Regular maintenance involves cleaning the surface and ensuring that any clogs or debris in the pores are cleared to maintain permeability.
