Permeable high grade asphalt concrete composition having excellennt adhesive property and constructing method using the same

摘要

The present invention comprises 5 to 8% by weight of an asphalt binder excellent in adhesive performance and 92 to 95% by weight of aggregate; The asphalt binder having excellent adhesion is to contain 70 to 85% by weight of petroleum-based asphalt, 15 to 25% by weight of a polymer modifier, 1 to 10% by weight of a plastic additive, and 0.1 to 1% by weight of a peeling inhibitor, and the petroleum-based asphalt is It is one or more selected from the group consisting of straight asphalt, cutback asphalt, blown asphalt, and mixtures thereof, and the polymer modifier is SBR, SBS, SIS, EPDM, polychloroprene, polynorbonene, polyolefin, EBA, SEBS, ABS, rubber, polybutene, ethylene copolymer, methacrylic acid ester, maleic anhydride, ethylene terpolymer, Glycidyl Methacrylate, ethylene-propylene copolymer, and one or more selected from the group consisting of mixtures thereof, and the plastic additive is EVA, EMA, copolymer olefin , C5 petroleum resin, C9 petroleum resin, and one or more selected from the group consisting of a mixture thereof, and the peeling inhibitor is one or more selected from the group consisting of amine-based, polyphosphoric acid-based, slaked lime and mixtures thereof; The polymer modifier further comprises 0.1 to 5% by weight of a partially reduced graphene solution based on the total weight of the polymer modifier; The porosity is 20 to 23%, the PG grade performance is high (PG 88-34), and the adhesion performance between coarse aggregates is improved to ensure high durability, while preventing aggregate separation, fatigue cracking, and low temperature cracking. The present invention relates to a water-draining high-grade asphalt concrete composition using an asphalt binder with excellent adhesive performance to improve resistance, and a construction method of a water-draining high-grade asphalt concrete using the same.
