WATER RETENTIVE-WATER PERMEABLE CONCRETE PAVEMENT

摘要

PROBLEM TO BE SOLVED: To suppress a temperature rise in a pavement surface by holding rainwater on an aggregate surface constituting a continuous void of water permeable concrete pavement. SOLUTION: Water retentive slurry 10 produced by mixing a binder composed of a polymer-based emulsion and recycled woody powder of an extremely small particle size by adding water is made to flow down in a void of the paved water permeable concrete pavement. A water retentive material surface hardened by forming a coating film of the predetermined thickness of the water retentive slurry 10 by being stacked on the surface 2 of an aggregate 1 covered with the water permeable concrete pavement.
