摘要
通过不同掺配关系的SBS改性沥青的试验,对SBS改性沥青的弹性恢复、高温稳定性和低温性能等路用性能进行了研究,分析了改性剂剂量等因素对SBS改性沥青性能的影响规律,改性剂剂量在3%～5%范围内变化时,改性沥青的各项指标呈逐渐增加趋势,即改性剂剂量越大,改性沥青的性能越好,改性沥青的合理改性剂剂量应在4%以上·提出了适合于辽宁省的SBS改性沥青路用性能指标技术标准,可供工程实际参考应用·
Through the testings for different proportioned SBS-modified asphalt, its pavement performance was investigated experimentally including elastic resilience,high-temperature stability and low-temperature property. How the influencing factors, such as dosage of the modifier used exert on the performance was thus analyzed. The optimal dosage of the modifier should be 4% or more. The technical specifications of SBS-modified asphalt available to road construction in Liaoning province is proposed as a reference for engineering applications.
