Benefits of Porous Asphalt

Public works departments around the United States are turning towards an innovative new pavement to solve flood control concerns.

Porous asphalt is gaining widespread acceptance across the country, while water flood control and preventing polluted water from running off into rivers and lakes are two of the most important reasons to use porous asphalt in your pavement project those are not the only reasons to consider using the material.

Water rapidly flows over the porous pavement surface. This improves skid resistance and provides an added layer of safety to your surface. For the Chicagoland market porous asphalt requires less salt than conventional asphalt. Sand cannot be used with porous asphalt because it clogs the pores and lessens the effectiveness of material.

Porous asphalt also provides the added advantage of providing one of the college pavement options to combat the urban heat island effect on extreme summer days.

Porous asphalt provides an effective weapon against the extremes of summer heat and winter’s snow and sleet. Even though porous asphalt has been around since the 1970s, the evolution of high-performance material and better engineering practices have improved upon the original design. Porous asphalt now consists of layers of open-graded mix placed on the top of a reservoir of crushed stone.

This mix provides solutions for parking lot or other programs fighting against flooding or other water concerns.
