Porous pavement is a green and sustainable alternative to traditional pavement. Porous pavement is a permeable pavement with a stone reservoir underneath that temporarily holds surface runoff, eventually draining into the subsoil.Although pervious concrete and porous asphalt may look the same as traditional concrete or asphalt, they do not behave the same.
Porous asphalt may also save on maintenance costs by hastening snowmelt and improving drainage. And finally, there is evidence that a porous asphalt overlay may be the right treatment for blacktop trails that are subject to cracking.

WINTER ROAD MAINTENANCE ON POROUS ASPHALT. Results from three different winter road maintenance periods indicate that the behavior of pavements made of asphaltic concrete and those of porous asphalt - even with varying grain mixes of 0/8 mm and 0/11 mm - did not differ markedly from each other and certainly not to an extent that would suggest discontinuing the use of the latter materials.
