Paving Block with Improved Illumination

Abstract

A paving block with improved illumination (luminescent paving block) preferably includes a concrete base layer and a photoluminescent layer. The photoluminescent layer is formed on top of the concrete base layer. The concrete base layer is preferably created by combining sand, aggregate, water, pigment and cement to form an uncured concrete mixture. The photoluminescent layer preferably includes very fine aggreagate, cement, water, pigment, sand and a polyester resin infused with a photoluminescent pigment or a silica-based glass material infused with photoluminescent pigment. Further, a light transmitting sealant may be placed over the photoluminescent material.
