Study on the Effect of Fly Ash to Modified Bitumen

Abstract:

Modified bitumen had been mainly studied in this thesis.The effect of the different quality ratio of petroleum asphalt/fly ash to SBS 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.
