City Demonstrates Porous Asphalt

Who says having holes in a parking lot is a bad thing? In 2013, the City of Burnsville replaced a 12,000-square-foot section of parking lot with porous asphalt. This surface is similar to standard asphalt, except that the smaller sand particles are left out to create voids in the pavement. This allows rainwater and storm melt to run THROUGH the surface into the ground, rather than running into storm drains.

Watch as the City demonstrates this relatively new surface. Burnsville plans to test out its endurance over the next few years before installing it elsewhere.
