Permeable Concrete Pavement Installation Advantages:
Capture rainwater infiltration into the ground to replenish groundwater and alleviate the rapid decline in groundwater levels, a city's ecological issue.
2. Offer a rich palette of color combinations to cater to the diverse preferences and aspirations of property owners, fulfilling personalized decorative creativity demands.
3. Increase the urban breathable area to regulate city climate and surface temperature, which is conducive to alleviating the urban "heat island effect."
4. Absorbs part of the mall's noise, creating a quiet and comfortable business environment, enhancing the quality of the community and commercial plaza.
5. Prevents road flooding during rain and reduces nighttime road glare, enhancing the comfort and safety for vehicles and pedestrians.
6. Easier to maintain than regular concrete; offers better integrity than permeable pavers, with a smooth surface and strong compressive strength.
The exposed aggregate permeable concrete flooring has a wide range of applications: Suitable for sidewalks, bike lanes, public squares, outdoor parking lots, light traffic lanes, park roads, as well as roadside and median strips, urban pedestrian paths, lightweight vehicular roads, ecological gardens, public green spaces, riverfront walkways, and more.
Specific construction steps for permeable concrete with exposed aggregates:
Extruded aggregate porous concrete is based on the construction of porous concrete roads. After the porous concrete paving is flat, an anticoagulant is sprayed, and the surface cement paste can be thoroughly washed away in *** days, revealing the natural color, shape, and luster of the stone, achieving a naturally non-artificially carved paving effect for the surface aggregates.
The porous aggregate permeable concrete pavement is constructed based on the method of permeable concrete, with the addition of an aggregate washing step to extract the aggregates, which is an extra process on top of the standard permeable concrete construction.
Summarily, it includes laying a gravel base, mixing aggregates, pouring a smooth surface, applying cleaning agent, washing away surface mud, curing, applying protective coating, and cutting expansion joints.
The link points between exposed aggregate aggregates decrease, with stricter details than required for permeable concrete. The key process in exposed aggregate permeable concrete is the application of a cleaning agent to alleviate the solidification time of surface sludge. The surface can be washed with water the next day, revealing the aggregates.
