摘要: 沥青结合料在浇筑式沥青混凝土中的作用至关重要,通过对普通改性沥青、湖沥青复合改性沥青、岩沥青复 合改性沥青和聚合物复合改性沥青进行基本性能对比试验,结果表明,复合改性沥青更适合用于浇筑式沥青混凝 土;对3种复合改性沥青的浇筑式沥青混凝土进行刘埃尔流动度、贯入度、低温弯曲和疲劳试验,研究3种复合改 性沥青的浇筑式沥青混凝土施工和易性、高温性能、低温性能和疲劳性能的差异,结果表明,岩沥青复合改性沥青 浇筑式性能与湖沥青复合改性沥青浇筑式性能相当,聚合物复合改性沥青浇筑式更适合于寒冷地区使用。

Abstract: Bitumen is especially important to Guss Asphalt (GA). Comparative tests of performance are carried out between the simple common asphalt, lack asphalt compound modified bitumen, sock asphalt compound modified bitumen and polymer compound modified bitumen, which show that compound modified bitumen is more suitable for GA; meanwhile,Lueer, penetration, fatigue and low-temperature bending tests on GA of above three compound modified bitumen are carried out, in order to research their differences of construction, high-temperature, low-temperature and fatigue performance. The results show that: the performance of sock asphalt compound modified bitumen GA is equivalent to lack asphalt compound modified bitumen GA, and polymer compound modified bitumen GA is more suitable for cold regions.

Key words: Guss Asphalt(GA) , lake asphalt, sock asphalt, polymer modified bitumen, high-temperature perform ance; low-temperature performance, fatigue performance
