• Abstract:
  The original purpose of this field trial and laboratory study was to evaluate the performance of seven different asphalt modifiers, representing some of the major types of modifiers, to determine which provided the best, most cost-effective performance improvement in terms of rutting and cracking resistance. All seven modifiers were included in hot mix asphalt mixtures placed on one project on I-465 in 1990. Two control sections using AC-20 were also constructed on the same project. During the course of this study, the Indiana Department of Transportation (INDOT) adopted the Superpave binder specifications and subsequently the Superpave mix design process. This study then offered an excellent opportunity to evaluate the modified binders used on this project according to the Superpave binder tests and to relate those test results to actual, long-term service performance. It also offered a unique opportunity to evaluate proposed new protocols for modified binder testing under AASHTO MP1a.
