To cope with the deficiency of high temperature stability in early damages for steel deck pavement, based on theory of polymer modification, three polymer modifiers were used to develop a new material for steel deck pavement by designed orthogonal test together with range analysis and synthesis score method. Performances of the compound modified asphalt and its mixture were measured, and the tests such as rutting test, low temperature bending test, water stability test and fatigue test were performed. The result shows that the compound modified asphalt has lower temperature susceptibility and better ability to resist shear deformation. The performance of the mixture was improved remarkably especially the capacity of rutting resistance, and its economic benefit is considerable, Thus the mixture is suitable for the steel bridge pavement.
