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, photoluminescent 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.

A method of manufacturing a paving block with embedded photoluminescent material, comprising the steps of:
- mixing sand, aggregate, water and cement to form an uncured concrete mixture;
- providing at least one of a photoluminescent mixture of a polyester resin infused with a photoluminescent pigment and a silica-based glass material infused with said photoluminescent pigment;
- curing said photoluminescent mixture, breaking said photoluminescent mixture into randomly sized chips or particles to form photoluminescent fragments;
- mixing said photoluminescent fragments, photoluminescent sand, cement and water to form an uncured luminescent mixture;
- providing a paving block mold;
- pouring said uncured concrete mixture into paving block mold;
- and
- pouring said uncured luminescent mixture to substantially fill said paving block mold.
