ACI 522R-10 (R2011) PDF Download

ACI 522R-10 (R2011) is a standard that provides a comprehensive report on pervious concrete. The report covers various aspects of pervious concrete including its application, design methods, materials, properties, mixture proportioning, construction methods, testing, and inspection. Pervious concrete refers to a type of concrete that has zero-slump and an open-graded structure.

The composition of pervious concrete typically includes portland cement, coarse aggregate, minimal or no fine aggregate, admixtures, and water. This combination results in a hardened material with interconnected pores ranging in size from 0.08 to 0.32 inches (2 to 8 mm), allowing water to easily pass through. The void content of pervious concrete can vary from 18 to 35%, and it typically has compressive strengths ranging from 400 to 4000 psi (2.8 to 28 MPa).

Pervious concrete pavement's drainage rate depends on the size of the aggregate and the density of the mixture. Generally, the drainage rate falls within the range of 2 to 18 gallons per minute per square foot (81 to 730 L/min/m2). This standard provides valuable information for engineers, designers, and contractors regarding the use and implementation of pervious concrete in various applications.
