Porous Rubber Pavement (PRP) is a new type of permeable pavement in North America. It consists of stone aggregates, crumb rubber from recycled tires, and polyurethane as a binder. Due to a higher percentage of air voids (27% to 29%) and flexible nature, it offers extensive environmental and safety benefits, including improved stormwater management, reduced skid resistance, hydroplaning and greater potential for road traffic noise reduction. In the North American context, this material is currently used for low traffic roads and pedestrian walkways as a surface material.
