摘要

The present invention comprises 8 to 16% by weight of an asphalt binder excellent in high and low temperature performance and 84 to 92% by weight of aggregate; The asphalt binder having excellent high and low temperature performance includes 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. Asphalt 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 a mixture thereof, and the polymer modifier is the polymer modifier. It further contains 0.1 to 5% by weight of a partially reduced graphene solution based on the total weight, and the plastic additive is at least one selected from the group consisting of EVA, EMA, copolymer olefin, C5 petroleum resin, C9 petroleum resin, and mixtures 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 aggregate passes 80 to 100% by weight in a 5mm sieve, 65 to 100% by weight in a 2.5mm sieve, 40 to 80% by weight in a 1.2mm sieve, 20 to 65% by weight in a 0.6mm sieve, 7 to 40 wt% pass through a sieve of 0.3 mm, 2 to 20 wt% pass through a sieve of 0.15 mm, and pass through a fine aggregate selected by passing through 0 to 10 wt% through a sieve of 0.08 mm, and 100 wt% pass through a sieve of 0.6 mm , Using a mixture of the filling material selected by passing 95 to 100% by weight in a sieve of 0.3mm, 90 to 100% by weight in a sieve of 0.15mm, and passing through 70 to 100% by weight in a sieve of 0.08mm; A high-grade asphalt concrete composition for an impermeable barrier layer using an asphalt binder having a porosity of 0.5% or less and having excellent plastic deformation resistance, fatigue crack resistance, and low temperature crack resistance and excellent high and low temperature performance; Construction method of high grade asphalt concrete for impermeable barrier layer using this; Paving method of drainage asphalt concrete including an impermeable barrier layer constructed using this; And it relates to a paving method of crushed stone mastic asphalt (SMA) concrete including an impermeable barrier layer constructed using the same.
