High grade asphalt concrete composition for thin overlay pavement and constructing method using the same

摘要

The present invention is a thin layer packaging that can form a high-temperature mixed asphalt, including 3 to 8% by weight of the asphalt binder, 85 to 95% by weight of the aggregate, 1 to 3% by weight of the filler, and 1.5 to 5% by weight of the high-temperature mixed modifier. As for grade asphalt concrete composition, The high-temperature mixed modifier includes an elastomer, a plastic polymer, an oil, a filler, a wax, and an additive for thin layer packaging, The additive for thin layer packaging is based on 100 parts by weight of polylactic acid resin, 40 to 60 parts by weight of fluorine resin, 30 to 50 parts by weight of isobornyl acrylate, 10 to 30 parts by weight of polyalkylene glycol, 5 to 25 parts by weight of triacetin, and Aluminum sulfate (Al
