Modified asphalt, mixture containing modified asphalt and application of modified asphalt
The invention provides modified asphalt, a mixture containing the modified asphalt and application of the modified asphalt. The invention specifically discloses modified asphalt. The modified asphalt is prepared from the following components: matrix asphalt, SBS (Styrene Butadiene Styrene), naphthenic oil and a composition A, the content of the SBS is 4.5%-6.5% of that of the modified asphalt; the naphthenic oil accounts for 3%-9% of the modified asphalt; the content of the composition A is 1%-3% of that of the modified asphalt; the composition A comprises hydroxyethyl ethylene bis stearamide and ethylene bis stearamide, and the mass ratio of the hydroxyethyl ethylene bis stearamide to the ethylene bis stearamide is (2: 1)-(1: 2); the percentage is mass percentage. The modified asphalt provided by the invention can realize construction at medium and low temperatures, ensures smooth proceeding of a pedestrian overpass pavement project, and achieves a good effect.
本发明提供了一种改性沥青、含其的混合料及其应用。本发明具体公开了一种改性沥青，其包括以下组分：基质沥青、SBS、环烷油和组合物A；所述SBS含量为所述改性沥青的4.5％‑6.5％；所述环烷油含量为所述改性沥青的3％‑9％；所述组合物A含量为所述改性沥青的1％‑3％；所述组合物A包括羟乙基乙撑双硬脂酰胺和乙撑双硬脂酰胺，所述羟乙基乙撑双硬脂酰胺和乙撑双硬脂酰胺的质量比为(2:1)‑(1:2)；所述百分比为质量百分比。本发明的改性沥青可实现在中低温下进行施工，保证了人行天桥铺装项目的顺利进行，取得了良好效果。
