Investigation of Low and High Temperature Properties of Plant Produced Rap Mixtures


The researchers would like to thank the contractors who put so much effort into designing, producing, and sampling the mixtures evaluated for this report and in phase I of this project. This was not an insignificant amount of effort, and it is greatly appreciated. In addition, the members of the Asphalt Pavement Association of Indiana and Brad Cruea and Don Lecklitner, assisted the research effort by arranging and supporting a technician for several months to perform binder extractions, recoveries, and binder testing. Josh Clark was extremely helpful and productive. Andrew Szabat, a Purdue University undergraduate, completed the extractions/recoveries. His assistance and patience is also appreciated.

The following individuals provided technical review of this report: Nelson Gibson, John Bukowski, Victor (Lee) Gallivan, Andy Mergenmeier, and John D’Angelo. Their efforts are appreciated.
