Title:
ELECTRICALLY CONDUCTIVE PAVEMENT MIXTURE
Document Type and Number:
WIPO Patent Application WO2002040807
Kind Code:
A3
Abstract:
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.
