Polyphosphoric Acid Modification of Asphalt Binders: A Workshop, April 7-8, 2009, Minneapolis, Minnesota
The modification of asphalt binder to improve performance properties has grown significantly since the implementation of the Strategic Highway Research Program (SHRP) binder specifications. There has been increased use of polymers, crumb rubber modifier, and polyphosphoric acid (PPA). This has caused concern by many highway agencies about the performance characteristics of PPA modification and possible negative interactions with other mix components, such as lime and liquid antistrips. There have been anecdotal stories about both failures and successes. This workshop was convened to address these concerns. The workshop pulled together the real facts about PPA-modified asphalt and its performance. Researchers and practitioners with real knowledge and experience presented the latest information on the PPA modification and performance characteristics. This E-Circular contains several papers and summaries of presentations on the evaluation of the performance characteristics of PPA-modified asphalt.
