The use of pervious concrete pavements is recommended by several U.S. environmental agencies as a Best Management Practice for stormwater control, which has increased their application to streets, parking lots, bike lanes, and sidewalks across the Pacific Northwest. However, with increased use of pervious concrete in areas with adverse winter weather, proper ice and snow control protocols must be developed to ensure the mobility and safety of drivers and pedestrians on pervious concrete installations. In a previous project, the researchers determined that the friction performance of pervious concrete pavement surfaces from one mixture design outperformed that of traditional concrete pavements in dry, wet, and icy conditions. This project will extend the scope of laboratory and field testing to include a wide range of mixtures and installations. The goal is to ensure mobility on various classes of pervious concrete pavements all year around.
