Arecent research project by the National Concrete Pavement Technology Center (National CP Tech Center) at Iowa State University investigated the use of pervious concrete as a surface-wearing course in cold-weather climates. This project is one of the largest and most comprehensive studies to date on pervious concrete. The research objective was to investigate optimal pervious concrete mix designs for wearing-course applications while addressing the issues of noise and skid resistance. The research has led to the conclusion that well-designed pervious concrete mixes can achieve strength, permeability and freeze-thaw resistance to allow use in cold-weather climates.
