摘要
彩色胶结料具有和石油改性沥青相当的沥青指标,但受原材料种类影响,高低温性能稳定性差。为分析不同类型原材料对彩色胶结料性能的影响,室内研究了不同分子量石油树脂、不同芳烃含量橡胶油对彩色胶结料高低温性能和温度敏感性的影响。试验结果显示,高软化点树脂会造成胶结料高低温性能不同程度的衰减,但对胶结料的增粘效果显著,高芳烃含量橡胶油可显著改善胶结料低温性能,且在一定程度上改善胶结料的温度敏感性,但对胶结料的高温性能指标造成不可避免的衰减。本文结论表明,可通过优选树脂和橡胶油原材料,制备不同技术指标要求的彩色胶结料。
Color binder material has the same asphalt index as petroleum modified asphalt, but it has poor stability of high and low temperature performances because of the kinds of raw materials. In order to analyze the effect of different types of raw materials on the color binder performance, this paper studies the effect of resin with different molecular weight, and rubber oil with different aromatics content on the high and low temperature performances and the temperature sensitivity of the color binder in laboratory. The results show that the resin with high softening point will cause the attenuation of high and low temperature performances in different degrees, but have the significant effect of viscosity for the binder material, the high aromatic content of rubber oil can significantly improve the low temperature performance of binder, and improve the temperature sensitivity of binder to a certain extent, but the high temperature properties of binder will cause the inevitable attenuation. The conclusion shows that the different technical indexes of color binder materials are prepared by the optimized resin and rubber oil raw material.
