Benefits of Porous Asphalt in Parking Lots

Wdrożenie porutu asfalt in parking lots delivers a wide range of environmental, economic, and safety providenges that make it a comelling choice for commercial, institutional, and municipal projects.

Superior Stormwater Management and Flood Reduction

A typical porous asfalt parking cat reduce runoff volume by 50 t 80 percent, dependiing on soil infiltration rates and system design. During god hary rain events, the stone convestirir stores water that gradual percolates into the ground, preventing thee abouming of municipain drainage systems.

Studies have shown that porous asfalt systems can accesse total suspended solids removal rates exceeding 80 percent, along with indistrant reductions in fosforus, nitrogen, bay metals, and hydrocarbon.

Reduction of Urban Heat Island Effect

Traditional dark asfalt absorbs solar radiation and can reach surface temperatures of 120- 150 ° F on hot summer days, contriping to the urban heat island effect.
