Baoding City High-Carrying Permeable Concrete Paving Material Manufacturer, Exposed Aggregate Permeable Pavement Construction Mix Ratio Standard

1. Concentrated rainfall can alleviate the burden on urban drainage facilities, preventing river flooding and water pollution.

3. Prevents ponding on road surfaces, reduces glare at night, enhancing road safety and driving comfort.

5. High porosity can reduce road noise during vehicle travel, creating a comfortable traffic environment.

7. Easy to maintain, gaps won't tear, and it's not prone to clogging.

Porous pavement roads add color to sponge city construction! The construction technology of permeable concrete is a crucial method to achieve the海绵ization of roads, facilitating the terminal collection of rainwater, storing moisture at the surface, and nourishing groundwater and surrounding vegetation. Porosity reaches 15-25%, mitigating the urban heat island effect.

Natural Aggregate Permeable Pavement Construction Steps: Mix a specified amount of stone, cement, binder, and water until well blended. Moisten the subgrade with water before laying, compact the sublayer to ensure flatness, and then smooth the surface layer with a cement smoothing machine. Cover the construction with agricultural film for two days of curing and then water it for maintenance, taking about five to seven days. Set up a separation zone during this period to prevent pedestrian traffic. Once the surface layer dries, apply a surface sealer (also known as a surface罩剂).
