Abstract:
Permeable and elastic pavement blocks comprising waste-polyurethane chips, which use a binder specially developed to secure the binding between an upper polyurethane-chip layer and a lower permeable-concrete layer as well as the binding among the waste-polyurethane chips, resulting in excellent strength and durability, and use recycled polyurethane chips to provide elasticity and permeability suitable for sports activities, walking, and outdoor exercises the like.
