Assessment of Winter Maintenance of Porous Asphalt and Its Function for Chloride Source Control

摘要: AbstractThis study presents the findings from research conducted at University of New Hampshire Stormwater Center (UNHSC) which investigated porous pavements as a potential strategy for minimizing use deicing chemicals winter maintenance. In cold regions, chloride is an integral component maintenance and safe usage transportation surfaces. Chloride-laden runoff impervious surfaces threatens aquatic habitats, degrades drinking water supplies, corrodes infrastructure. State federal environmental agencies are beginning to regulate through implementation total maximum daily loads (TMDLs). Parking in some watershed studies have been shown be single largest source storm-water runoff, instances contributing up 50% load. This examined over two winters 38 storms 2006–2008. The evaluated performance response practices by measuring skid resist...
