IMPROVED PERFORMANCE OF PAVING ASPHALTS BY POLYMER MODIFICATION (WITH DISCUSSION)
There are essentially four generic classes of polymers which have been shown to lead to improved properties of bituminous binders, these are: (1) thermoplastics, (2) rubbers, (3) thermosets, and (4) thermoplastic block copolymers. The structure and properties of the latter have been reviewed. The authors have compared the rheological characteristics of binders with corresponding mixture properties including dynamic creep and wheel tracking. They also address the impact of the judicial selection of asphalt type (i.e., crude slate and method of manufacture) and asphalt grade (e.g., AC-5 through AC-40). The influence of these variables on the rheology, compatibility, morphology, and overall performance of modified asphalt cements is also discussed.
