Performance optimization of composite modified asphalt sealant based on rheological behavior
Highlights We determined best contents of raw materials of composite modified asphalt sealant. Central composite design is effective in optimizing performance of composite modified asphalt sealant. It is effective to use energy method to evaluate viscoelastic properties of asphalt. We analyzed the effects of rubber powder, additive, SBS and SBR on rheological behavior of modified asphalt.
Abstract In order to improve the performance of composite modified asphalt, the central composite design-response surface methodology was used to determine the optimum content of raw materials. The rheological behavior including accumulation of deformation, viscoelastic ratio, creep strength, creep strain rate “m” was analyzed by testing in central composite model. Response surface of the overall desirability was established. The test results indicated that the optimum raw materials ratio was asphalt:rubber powder:additive:SBS:SBR=100:25:7:5:3 (by weight). Central composite design could be used in optimization of the content of raw materials. It is effective to use energy method to evaluate viscoelastic properties of asphalt.
