Patent number: 6971819Abstract: An electrically conductive paving system that has enhanced conductivity of the conductive graphite/asphalt layer. This is achieved by incorporating into the paving mixture a blend of two naturally occurring crystalline flake graphites, one being coarse (generally larger than 40 mesh/425 microns) and the other being fine (generally smaller than 100-200 mesh/150-75 microns). The ratio of course flake graphite to fine flake graphite may be from 1.5:1 and 1:1.5, but is preferably approximately 1:1.Type: GrantFiled: November 16, 2001Date of Patent: December 6, 2005Assignee: Superior Graphite Co.Inventors: Peter L. Zaleski, David J. Derwin, Walter H. Flood, Jr.

Patent number: 6851236Abstract: A horizontally level raised terrace floor system for mounting over a non-level or irregular substructure that includes a plurality of spaced apart support pedestals that are fabricated of a heat shearable foam material. Each pedestal is mounted upon the non-horizontally level substructure and the pedestals are heat sheared so that the top surface of each pedestal lies in a common horizontal plane above the substructure. A plurality of flat grates are placed directly upon the pedestals in an edge to edge relationship. A plurality of interlocking paving blocks are laid down over the grates to provide a tight deck over the grates.Type: GrantFiled: January 24, 2001Date of Patent: February 8, 2005Assignee: Syrstone, Inc.Inventor: Jeffrey T. Harvey

Patent number: 6830408Abstract: A system for repairing roads is provided. The system includes a highly strain tolerant, substantially impermeable, reflective crack relief interlayer. The interlayer includes a polymer modified asphalt binder mixed with a dense fine aggregate mixture. About 100% of the aggregate should be able to pass through about a 9.5 mm sieve. The interlayer mix is designed using volumetrics and verified using a Flexural Beam Fatigue test and a Hveem Stability test. Preferably, an HMA overlay that is compatible with the interlayer, as well as the demands of local traffic, is placed over the interlayer so that a protected, smooth road surface is provided. The system may delay the first appearance of cracks and the severity of cracks for several years compared with traditional hot mix overlays and extend pavement service life.Type: GrantFiled: October 20, 2003Date of Patent: December 14, 2004Assignee: KMC Enterprises, Inc.Inventors: Phillip B. Blankenship, Joseph Drbohlav, III, Michael L. Hines
