Experimental Research on Crumb Rubber and Polyphosphoric Acid Composite Modified Asphalt Binders
In order to research the properties of crumb rubber (CR) and polyphosphoric acid (PPA) composite modified asphalt binders, an orthogonal test design is employed to arrange the experimental program. Three particle sizes of CR, three contents of CR and PPA were representatively selected as three influencing factors and levels. A total of nine composite modified asphalt binders were produced in laboratory and the conventional penetration grading indexes including penetration, softening point and ductility were conduced. The results indicate that the properties of composite modified asphalt binders are improved not only at high temperatures but also at low temperatures compared to the base asphalt binder. Based on variance analysis, the optimal proportion of CR and PPA composite modified asphalt is recommended.
