Asphalt is America’s most recycled material Reclaimed asphalt is not just reusable as a "black rock" — the asphalt cement in the reclaimed pavement is reactivated to become an integral part of the new pavement The recycled asphalt cement replaces part of the new asphalt cement required for the pavement, reducing costs for road agenci.

Porous Asphalt Pavement Description Porous asphalt pavement is a paved surface and subbase comprised of asphalt, gravel, and stone, formed in a manner resulting in a permeable surface The various layers, called "courses," have the potential for stormwater detention Stormwater which passes through the pavement may completely.

Porous asphalt is the same as regular asphalt except it is manufactured with the fine material omitted, leaving open spaces that allows water to filter through to a “recharge” , A brief description of construction details is available in Massachusetts Low Impact Development Fact Sheet #6 (Reference 4) and in Montgomery County Permeable Paver.

Raveling (very porous asphalt) Raveling is the on-going separation of aggregate particles in a pavement from the surface downward or from the edges inward Usually, the fine aggregate wears away first and then leaves little “pock marks” on the pavement surface.

Permeable paving is a method of paving vehicle and pedestrian pathways that allows for infiltration of fluids In pavement design the base is the top portion of the roadway that pedestrians or vehicles come into contact with The media used for the base of permeable paving may be porous, to allow for fluids to flow through it, or nonporous media that are spaced so that fluid may flow in.

Properly maintaining asphalt by repairing any patches will save money later Potholes and cracks quickly turn from bad to worse When asphalt is not maintained properly, it oxidizes and dries out, turning it grey and brittle When this happens, the porous asphalt can allow more water to penetrate the surface causing cracks to form at a quicker.
