This report presents the results of an investigation of the performance of a variety of materials added to asphalt binders and mixtures to change their properties, particularly with respect to rutting and cracking. The approach included a field trial of seven polymer and particulate modifiers, supplemented by laboratory characterization of the materials used in the field. The modifiers evaluated included PAC, Novophalt, Multigrade asphalt cement, polyester fibers, Neoprene, SBR and asphalt rubber. The field trial showed that different modifiers do yield different performance. Modifiers are not essential to ensure that the pavement will not rut. None of the mixtures evaluated here exhibited appreciable rutting. Dramatic differences were noted in the cracking behavior, however. Newly developed laboratory tests were able to identify binders that would be more prone to cracking. All of the materials evaluated did change the properties of the binders or mixtures in some way. Some of the modifiers, however, were more effective at modifying the properties to provide improved field performance in a cost effective manner.
