| Abstract: | 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. |
