The use of permeable pavements originated in Europe more than 70 years ago (Knapton 2009). They started as various forms of open aggregate or grass pavements to promote water infiltration instead of runoff. They were reinforced with a variety of cell structures using concrete or plastic materials to enhance their load carrying capacity. In the 1970
