Estimating the term…
An electrically conductive paving mixture for use in a pavement system which prevents the accumulation of frozen precipitation on surfaces, for example, like that of an airport runway. The pavement system comprises a layer of electrically conductive paving mixture, a layer of insulative paving mixture, electrically resistive cables, an electrical power supply, sensors for measuring humidity and temperature, and a control and monitoring system. The electrically conductive paving mixture comprises a blend of naturally-occurring amorphous graphite and synthetic graphite/desulfurized petroleum coke. Preferably, the blend of naturally-occurring graphite to synthetic graphite/desulfurized produced coke is in the ratio of 2:1.
