Abstract:
In order to evaluate the road performance and economic benefit of SBS modified asphalt, by using the colloid grinding technology in asphalt plant to produce modified asphalt in different SBS contents, and to compare the performances of finished modified asphalt and asphalt mixture, the range of SBS modifier content and the evaluating standards of technical indexes to low dosage modified asphalt were put forward based on the road performance and economical efficiency. The results show that the high temperature stability and water stability of low dosage modified asphalt mixture can basically meet the demands of common SBS modified asphalt mixture when the mixing amount of SBS modifier is reasonable for meeting the production requirement, its economyperformance index is even superior to the common SBS modified asphalt mixture. When the mass ratio of SBS content is 3%, the economyperformance index is the biggest. 6 tabs, 3 figs, 11 refs.
