摘要
A modified additive for recycled waste asphalt concrete comprising specified additives in constant composition is provided to improve physical properties of the concrete in constructional field by homogeneously admixing petroleum oil, adhesion aid, polymer modifier, compatibilizer, thermal stabilizer and weather-proofing agent together. The additive includes: 40 to 80wt.% of petroleum based processing oil; 4 to 35wt.% of adhesion aid; 15 to 35wt.% of polymer modifier; 0.5 to 5wt.% of compatibilizer; 0.2 to 5wt.% of thermal stabilizer; and 0.1 to 5wt.% of weather-proofing agent. The thermal stabilizer is hydroxytoluene butyrate. The petroleum based processing oil is at least one or more selected from naphthene, paraffin and aromatic oil alone or in combination. The adhesion aid is at least one or more selected from C9 petroleum resin, C6 petroleum resin, C9 to C6 copolymeric petroleum resin, petroleum maleate resin, esterified petroleum resin, rosin ester, phenol resin and pine resin.
