Using the Industrial Wastes in the Base Layer of Pavement

Abstract

This paper evaluates the possibility of using artificial aggregates from blast furnace slag, considered industrial waste, which can replace, in a certain dosage, the natural aggregates in the composition of an AB 22,4 asphalt mixture. Furthermore, it is presented the possibility to replace the usual filler with powders from industrial wastes such as the desulphurization waste, generated by the combustion of the energetic coal.
