摘要：
本发明涉及一种SBR复合改性沥青及制备方法。该SBR复合改性沥青，按重量份计，包括沥青88~100份、SBR改性剂6~12份；所述SBR改性剂，按重量份计，包括：蒙脱土4~8份、硫磺3~8份、石油树脂10~16份、丁苯橡胶15~25份。经改性后的SBR沥青其高低温性能、抗老化性能均得以明显增强。
摘要（英）：

The invention relates to an SBR composite modified asphalt and a preparation method thereof. The SBR composite modified asphalt comprises, by weight, 88-100 parts of asphalt and 6-12 parts of an SBR modifier; and the SBR modifier comprises, by weight, 4-8 parts of montmorillonite, 3-8 parts of sulfur, 10-16 parts of petroleum resin and 15-25 parts of styrene-butadiene rubber. The high and low temperature performances and the aging resistance of the modified SBR asphalt are significantly enhanced.
