<p>Asphalt concrete is provided. The asphalt concrete comprises 100 weight parts pulver- izedwaste asphalt concrete, 50 to 130 weight parts coarse aggregate, 50 to 70 weight parts fine aggregate, 10 to 40 weight parts cement, 10 to 20 weight partsasphalt emulsion, 3 to 5 weight parts additive, and 1 to 3 weight parts reformer, wherein the additive is composed of 15 to 20wt% ethyl acrylate(EAM), 15 to 20wt% methyl methacrylate(MMA), 30 to 35wt% naphthene- based base oil, and 30 to 35wt% aromatic base oil, and the reformer is composed of 10 to 15 wt% natural hydrocarbon resin(NHR), 5 to 10wt% styrene butadiene rubber(SBR), and 75 to 85wt% cellulose. Upon pavement using the recycled asphalt concrete, the environmental damage due to waste landfill and collection of aggregate is reduced, and the costs are saved through reduction in use of asphalt and aggregate.</p> |
