摘要
阐述了SBS改性沥青低温延度的主要影响因素。通过对基质沥青针入度、反应温度、循环剪切时间及储存条件等进行优化和控制,可提高产品低温延度质量,延缓产品的老化, 储存周期明显改善。
Factors influencing low temperature ductility of SBS modified asphalt was analyzed . By optimum controlling of base asphalt penetration, reaction temperature , recycle shearing time and storage conditions, the low temperature ductility of SBS modified asphalt was improved and the time of storage stability was prolonged obviously.
