COLD ASPHALT CONCRETE MIXTURE AND ROAD PAVING METHOD USING THE SAME
According to an embodiment of the present invention, provided is a cold asphalt concrete mixture comprising 60-93 wt% of aggregate, 1-6 wt% of a filler, 3.0-10 wt% of cationic emulsified asphalt, and 0.1-10 wt% of an emulsion-based additive. The cationic emulsified asphalt comprises 40-65 parts by weight of asphalt, 0.1-3.0 parts by weight of an emulsifier, 0.1-2.0 parts by weight of calcium chloride, 0.01-1.0 parts by weight of hydrochloric acid, 45-60 parts by weight of water, and 0.1-3.0 parts by weight of a mixture of an acrylic polymer and polyvinylacetate (PVAc). The emulsion-based additive comprises one selected from the group consisting of carbon black, an acrylic polymer, PVAc, and a mixture of two or more thereof. Occurrence of carbon dioxide and harmful gas is controlled through cold construction, and fuel costs are reduced, so economical feasibility is improved and service life of a paved road may be enhanced.
