摘要

本研究采用PEG和TiO2改性60/70级纯沥青的性能。通过渗透等级、软化点、燃烧点和闪点、延展性和x射线衍射研究改性沥青样品的物理和结构性能。结果表明,基础沥青的物理性能与聚合物含量有关。在第一阶段,沥青以不同比例(2%、4%、6%和8%)与聚乙二醇混合。观察到,随着聚合物含量的增加,样品的刚度增加,从而导致渗透和延性值的降低。软化点随着聚合物浓度的增加而增加。然而,在6%的温度下,火点和闪点分别达到250°C和240°C的最大值,在8%的温度下分别下降到242°C和238°C。聚合物的最佳含量为6%。在第二阶段,研究了不同比例的TiO2(1.5%和3%)掺入PEG改性沥青的效果。对纳米改性沥青和聚合物改性沥青进行了XRD分析。观察到层间间距值(d)的增加,证实了PEG在纯沥青中的成功嵌入。在聚乙二醇改性沥青中掺入TiO2会影响聚合物改性沥青的物理性能。

“Modification of bitumen properties using polyethylene glycol and titanium dioxide (TiO2)”
In this study, PEG and TiO2 were used to modify the properties of neat bitumen of grade 60/70. The physical and structural properties of the modified bitumen samples were investigated using penetration by grade, softening point, fire and flash point, ductility, and x-ray diffraction. Results showed that the physical properties of base bitumen were dependent on the polymer content. In the first phase bitumen was blended with PEG at different proportions (2%, 4%, 6%, and 8%). It was observed that stiffness in samples increases as we increase the polymer content which leads to a decrease in penetration and ductility values. The softening point increased with increasing polymer concentration. However, fire and flash point attained maximum value of 250°C and 240°C at 6% and decreased to 242°C and 238°C at 8% respectively. The optimal polymer content was found to be 6%. In a second phase, the effects of incorporation of various percentages of TiO2 (1.5% and 3%) in PEG modified bitumen have been investigated. XRD analysis has also been performed for nano and polymer modified bitumen. An increase in the interlayer spacing value (d) was observed which confirms the successful intercalation of PEG in neat bitumen. Incorporation of TiO2 in PEG modified bitumen affects the physical properties of polymer modified bitumen.
