Advantages of Permeable Concrete Paving:
1. Harvesting rainwater to infiltrate the ground, replenishing groundwater, and alleviating the rapid decline of groundwater levels—a city's ecological issue.
2. Offer a rich palette of color combinations, catering to the diverse preferences and aspirations of property owners, to fulfill personalized decorative creative requirements.
3. Increase urban ventilation area to regulate city climate and ground temperature, which is beneficial for alleviating the urban "heat island effect."
4. Absorbs part of the mall's noise, creating a quiet and comfortable commercial environment, enhancing the quality of the community and business plaza.
5. Prevents road flooding during rain and reduces nighttime road reflections, enhancing the comfort and safety of vehicle and pedestrian traffic.
6. Easier to maintain than regular concrete; offers better overall integrity, a smooth surface, and stronger compressive strength compared to permeable pavers.

The porous concrete with exposed aggregates has a wide range of applications: Suitable for sidewalks, bike lanes, public squares, outdoor parking lots, light traffic lanes, roads within parks and along both sides of roads, central dividers, urban pedestrian paths, lightweight vehicle lanes, ecological gardens, public green spaces, river景观 walkways, and more.

Specific construction steps for permeable concrete with exposed aggregate:

Porous Aggregate Permeable Concrete is constructed based on the paving of permeable concrete roads. After the permeable concrete paving is levelled, an admixture is sprayed, and the surface cement paste can be thoroughly washed away with a simple rinse after *** days, showcasing the natural color, shape, and luster of the stone, achieving a naturally laid surface without any artificial carving.

The exposed aggregate permeable concrete pavement is constructed based on the method of permeable concrete, with the additional step of washing out aggregates from the exposed aggregate.

Briefly, it involves laying a crushed stone base, mixing aggregates, pouring a smooth surface, applying cleaning agent, washing off surface mud, maintenance, applying protective agent, and cutting expansion joints.

The link points between the exposed aggregates decrease, with stricter details than required for pervious concrete. The key process in exposed aggregate pervious concrete involves applying a cleaning agent to alleviate the setting time of the surface slurry, allowing the surface to be washed with water the next day, thereby revealing the aggregates.
