Abstract
The present application relates to an electrically conductive asphalt mastic (ECAM) composition that includes an asphalt binder, a mineral filler, and a plurality of conductive carbon microfibers, between 3 and 12 mm in length, which are the sole source of electrical conductivity in the ECAM composition where the conductive carbon microfibers and the mineral filler are dispersed in the asphalt binder, and wherein said conductive carbon microfibers are present in the ECAM composition in an amount of less than 2.00% of total volume of the ECAM composition. The application further relates to an electrically conductive asphalt concrete (ECAC) composition that includes an asphalt binder, a mineral filler, an aggregate, and a plurality of conductive carbon microfibers, where the conductive carbon microfibers are the sole source of electrical conductivity in the electrically conductive asphalt concrete composition.
