Conductive asphalt has the potential to satisfy different multifunctional applications. The behavior and the electrical and mechanical properties of this asphalt concrete have been modified using conductive additives, which can improve the durability of the asphalt mix and the service life of the pavement system. Among these additives are steel fibers. The results obtained indicate that the direct tensile strength of bituminous mix, the resistance to cracking, the energy, and the ductility modulus are increased with an increase in the percentage of steel fibers. Electrical resistivity decreased with the addition of steel fibers. So it is concluded that tensile strength increases reversibly with increasing electrical resistivity.
