基质沥青性质与SBS改性沥青性能相关性研究
|
摘要
选取5种典型基质沥青,在相同条件下进行SBS改性,研究基质沥青理化性质和SBS改性沥青性能的相关性。结果表明:基质沥青氢碳比、比重、Ic与SBS改性沥青高温性能、135℃黏度相关度最好,热重残留质量比、氢碳比与SBS改性沥青低温性能相关度最好,以上性质可作为SBS改性沥青原料选择的依据。
Five kinds of typical base asphalts were selected and modified by SBS under the same conditions. The correlation between the physical and chemical properties of base asphalts and the performance of SBS modified asphalt was studied. The results showed that the base asphalts hydrogen-carbon ratio, specific gravity, Ic had close correlation with SBS modified asphalt high-temperature performance and the viscosity at 135 °C.The thermogravimetric residual mass ratio and the hydrogen-carbon ratio had close correlation with the SBS modified asphalt low-temperature performance. The above conclusion can be used as the basis for the selection of SBS modified asphalt raw materials.
