What type of surface is asphalt classified as?

Asphalt is classified as a porous distributive surface. This means it has the ability to allow water and other liquids to permeate through it, which can help manage water runoff in various applications, including roadways and parking lots. The porous nature of asphalt helps to prevent flooding and reduces the potential for ponding water, as it can absorb and distribute moisture. This characteristic is particularly beneficial in urban environments where impervious surfaces can lead to water management issues.

The design of asphalt allows it to maintain structural integrity while also providing a layer that can manage water effectively. This contrasts with surfaces that are completely nonporous, which would not allow any liquid infiltration, thus increasing the chances of surface runoff and related problems.
