There are a variety of pervious alternatives to traditional pavements. Although there are several variations, they all share one common feature: the design of the base materials is critically different from traditional pavements. The different design ensures that water moves quickly from the surface to the subgrade materials, reducing or eliminating the chance of frost heaving, and encouraging groundwater recharge.
