The increasing availability of aggregates as road pavement materials and road pavement forming materials are increasingly limited in numbers shown by the dredging of rivers and cliffs in the mountains. Thus, other materials are used, namely concrete waste originating from the residual compressive strength test of concrete as a substitute for coarse aggregate that is obtained easily and cheaply to overcome the increasingly reduced availability of natural aggregates in Indonesia and one of environmental preservation system. The shortage of concrete waste has a high absorption, so to overcome it is needed additional substances in the form of Wetfix-Be. Laboratory-scale experimental testing method is testing Marshall characteristics using the proportion of concrete waste and crushed stone that is 0/100, 40/60, 80/20, 100/0. For Wetfix-Be levels used are 0%, 0.15%, 0.25%, 0.35%, of the weight of asphalt. The results of the study using concrete waste and Wetfix-Be as an aggregate and asphalt mixture can improve the quality of the flexible pavement layers in the AC-WC (Asphalt Concrete Wearing Coarse) mixture so as to reduce waste in the form of concrete residues in Indonesia.
