摘要
针对沥青质含量较高的塔河原油 ,采用适当的工艺开发出了符合 JTJ0 3 6— 1 998技术要求的 SBS和 SBR改性道路沥青。对于 SBS改性沥青 ,通过加入稳定剂使 SBS与基础沥青反应形成了一相 ,从而解决了储存稳定性。对于 SBR改性沥青 ,SBR的加入量对改性沥青的性能影响最大。通过比较表明 ,塔河油 SBS和
SBS and SBR modified paving asphalt have been developed from Tahe crude oil which contains much asphaltene. By adding stabilizer to SBS modified paving asphalt, SBS and base asphalt form a homogeneous system and thus its storage stability has been improved. For SBR modified asphalt, the amount of SBR that is added into the asphalt has a great effect on the performance of it. By contrast, SBS and SBR modified asphalt from Tahe crude oil exhibit less sensitivity to changes in temperature, and excellent high and low temperature properties.
