摘要
以南美原油切割后的减压渣油为原料,在一定试验条件下,考察了改性剂、相容剂掺量对改性沥青性能的影响,确定了生产高质量的I-C、I-D改性沥青的配方。试验表明:不同掺量的改性剂及相容剂对改性沥青的改性效果不同,通过两种助剂的添加配比的调整及优化,可以得出优于普通I-C、I-D级技术指标的高指标SBS改性沥青配方。
The effects of modifiers and compatibilizer on the perfromance of modified asphalt are investigated under certain experimental conditions with vacuum residue cut from South American crude oil as raw material,and the formulations for producing high quality I-C and I-D modified asphalt are determined.The results show that the modified asphalt has different modification effects with different dosages of modifiers and compatibilizers.By adjusting and optimizing the ratio of the two additives,the high-index SBS modified asphalt formula can be obtained,which is superior to the ordinary I-C and I-D technical indexes.
