摘要
主要研究了粉煤灰含量对石油沥青性能的影响,探讨了不同质量比的石油沥青/粉煤灰对于SBS改性沥青性能的影响,同时研究了不同用量的芳烃油、SBS对改性石油沥青性能的影响.研究结果表明,石油沥青和粉煤灰的比例在一定范围内,使改性沥青的延度等指标完全满足SBS I-C标准.当石油沥青与煤沥青的质量比为60/22时,其综合性价比达到最佳值,为降低改性沥青的生产成本进行了有益的尝试.研究还发现,对于本改性体系,芳烃油和SBS的用量对于沥青的改性有较大的影响.
Modified bitumen had been mainly studied in this thesis.The effect of the different quality ratio of petroleum asphalt/fly ash to modified bitumen had been discussed.The effects of different aromatic oil and SBS to the properties of modified bitumen were also studied.The results showed that the ductility of modified bitumen can satisfy standard of SBS I-C by the addition of the ratio of asphalt and coal tar pitch in a certain range.When the different quality ratio of Petroleum asphalt and fly ash was 60/20,the comprehensive cost achieved the best value.The result also revealed that there is an obvious influence of the modified bitumen as a result of content of aromatic oil and SBS in this modified system.
