The Effect of Adding Steel Fibers and Graphite on Mechanical and Electrical Behaviors of Asphalt Concrete

Conductive asphalt concrete can satisfy different and multifunctional applications such as heating roads to get rid of snow ice assure auto-detection, auto-cure, energy recovery. This research aims evaluate the performance with additives like steel fibers graphite powder. work is based on destructive tests (direct tensile test FENIX) non-destructive (electrical resistivity measures). The obtained results indicate that resistance, dissipated energy, ductility module increased increasing fiber percentage. Direct strength, cracking percentage increased, while decreased. Electrical decreased when it added graphite. Therefore, found strength reversibly electrical resistance. When adding or powder, conductive higher than significantly fibers, compared resistance optimal at 1% better mechanical performance. Doi: 10.28991/CEJ-2022-08-02-012 Full Text: PDF
