Porous asphalt mixture with alternative aggregates and crumb-rubber modified binder at reduced temperature

Abstract: This paper studies the design and characterization of a PA mixture with 91% of EAF slag, using a commercial CRM binder. A fatty acid amide wax was added to decrease the mixture manufacturing temperature. The mechanical performance of the designed mixtures was studied with the determination of void characteristics, water sensitivity, and particle loss in dry and wet conditions. Finally, their compactability, stiffness and fatigue resistance were also analysed. The addition of the wax allowed to decrease the manufacturing temperature 15 °C. Besides, the wax increased the complex modulus of bitumen, increasing also the elastic component and decreasing the thermal susceptibility, although these modifications did not have a significant impact in the mechanical performance of the mixture.
