PURPOSE: A colored asphalt mixture using a colored recycled material is provided to have the same color expression as charcoal material wood aggregate or a color pigment by mixing a colored recycled material from which foreign substance is removed, the charcoal material wood aggregate, asphalt, and a binding material having a certain composition in an optimum ratio. CONSTITUTION: A colored asphalt mixture comprises: 5-40 wt% of recycled aggregate of a colored recycled material(A), 5-40 wt% of charcoal material wood aggregate(B), 5-40wt% of asphalt(C), and 1-15wt% of a binding material(D). The charcoal material wood aggregate comprises: 55-70 wt% of gravel having 13-15 mm of particle diameter, and 10-15 wt% of sand having 0.1-0.5 mm of particle diameter. The binding material comprises: 20-60 wt% of MMA_PMMA polymer(d1), 0.5-10 wt% of MAA(methylacrylicacid)(d2), 20-60 wt% of water(d3), 0.5-10 wt% of an emulsifier(d4), 0.1-5 wt% of a cross-linking agent(d5), and 0.1-5 wt% of a polymerization initiator(d6). The MMA-PMMA polymer is manufactured by dissolving 10-20 wt% of polymethyl methacrylate(PMMA) powder to 80-90 wt% of methyl methacrylate(MMA).
