Sealcoat System

Abstract

A sealcoat system for providing a sealcoat that is free of silica. The sealcoat system generally includes providing a sealer, crushed glass, water and an additive, mixing the sealer together with the crushed glass, water and additive to form a sealcoat composition, and applying the sealcoat composition to a road. The crushed glass is preferably comprised of soda-lime glass and is further preferably comprised of container glass used in the production of bottles and jars.

The invention claimed is: 
     
         1 . A sealcoat for use in sealing a surface, comprising:
 a sealer; and   crushed glass within said sealer.   
     
     
         2 . The sealcoat of  claim 1 , wherein said crushed glass is comprised of soda-lime glass. 
     
     
         3 . The sealcoat of  claim 1 , wherein said crushed glass is comprised of container glass. 
     
     
         4 . The sealcoat of  claim 1 , wherein said crushed glass is comprised of recycled glass cullet derived from glass containers. 
     
     
         5 . The sealcoat of  claim 1 , wherein said crushed glass is purified by a purification process. 
     
     
         6 . The sealcoat of  claim 6 , wherein said purification process is comprised of a heat process. 
     
     
         7 . The sealcoat of  claim 1 , wherein said crushed glass is comprised of a size of approximately 360 mils. 
     
     
         8 . The sealcoat of  claim 1 , wherein said crush glass is comprised of a size of between 20 to 75 mesh AFS. 
     
     
         9 . The sealcoat of  claim 1 , wherein said crushed glass does not include flat glass. 
     
     
         10 . The sealcoat of  claim 1 , wherein said sealer is comprised of an asphalt emulsion sealer, a coal tar emulsion sealer or oil based sealer. 
     
     
         11 . A sealed asphalt road, comprising:
 an asphalt road having an upper surface; and   a sealcoat attached to said upper surface of said road, said sealcoat comprised of a sealer and crushed glass within said sealer.   
     
     
         12 . The sealed asphalt road of  claim 11 , wherein said crushed glass is comprised of soda-lime glass. 
     
     
         13 . The sealed asphalt road of  claim 11 , wherein said crushed glass is comprised of container glass. 
     
     
         14 . The sealed asphalt road of  claim 11 , wherein said crushed glass is comprised of recycled glass cullet derived from glass containers. 
     
     
         15 . The sealed asphalt road of  claim 11 , wherein said crushed glass is purified by a purification process. 
     
     
         16 . The sealed asphalt road of  claim 16 , wherein said purification process is comprised of a heat process. 
     
     
         17 . The sealed asphalt road of  claim 11 , wherein said crushed glass is comprised of a size of approximately 360 mils. 
     
     
         18 . The sealed asphalt road of  claim 11 , wherein said crush glass is comprised of a size of between 20 to 75 mesh AFS. 
     
     
         19 . The sealed asphalt road of  claim 11 , wherein said crushed glass does not include flat glass. 
     
     
         20 . The sealed asphalt road of  claim 11 , wherein said sealer is comprised of an asphalt emulsion sealer, a coal tar emulsion sealer or oil based sealer.
