Porous asphalt definition

Porous asphalt means a type of permeable pavement made with a flexible pavement similar to standard asphalt that uses a bituminous binder with the fine material reduced to form voids between the aggregate and allow water to infiltrate.

Porous asphalt means paving surfaces similar to conventional asphalt but with reduced fines and stable air pockets within the final product that allow water to drain to the base below, reducing stormwater runoff and allowing for groundwater recharge. Aggregate binders and additives can be added to increase durability.
