| 摘 要： | 为了研究SBS(styrene-butadiene-styrene)/HON(Honeywell TitanTM)复合改性沥青的流变性能,选取2种SBS和2种HON改性剂制备复合改性沥青,采用布氏旋转黏度计分析了复合改性沥青的黏温性能,采用动态剪切流变仪(DSR)、低温弯曲流变仪(BBR)分别评价复合改性沥青的高温及低温流变性能.结果表明:HON可有效改善沥青的黏温性能,降低施工温度,并可提高沥青的高温流变性能;SBS可明显改善沥青材料的高温流变性能,并可在一定程度上提高沥青材料的低温流变性能.

| Abstract: | In order to study the rheological properties of SBS ( styrene-butadiene-styrene )/HON (Honeywell TitanTM) modified asphalt, two kinds of SBS and HON were selected to prepare SBS/HON modified asphalt. The Brookfield viscometer was used to test the viscosity of composite modifiedasphalt at 135℃ and 165 ℃ respectively. The dynamic shear rheometer ( DSR ) and bending beam rheometer ( BBR) were conducted to examine the high and low temperature rheological properties respectively. The results show that HON can effectively enhance the viscosity-temperature characteristics and high temperature rheological performance of composite modified asphalt. SBS can effectively improve the high temperature rheological performance, while enhance the low temperature rheological performance to a certain degree. |
