This investigation is about the development ofasphalt blended with Electric Arc Furnace Dust (EAFD) generated as byproduct from the steelmaking industry in Colombia. EAFD is considered a hazardous waste due to its heavy metal high contents. Five mixtures of asphalt with 0, 1, 5, 10, and 20wt% of EAFD were fabricated using a mechanical mixer. Microstructure and particle distribution was evaluated by optical, and scanning electron microscopies. Penetration, softening point, and viscosity tests were conducted over all compositions. Results show a good powder distribution in the asphalt matrix. Penetration point increases up to 10wt% of waste and then decreases. Complementarily, softening point decreases after 5wt% having a minimum in 10wt%.
