Case Study: Implementation of Polyphosphoric Acid Modification of Asphalt Binders and Related Experience
This paper provides a case study demonstrating how a regional asphalt supplier located in Glendale, Arizona implemented polyphosphoric acid (PPA) as an asphalt modifier. This modification approach was necessitated by a change in asphalt binder selection strategy on the part of the Arizona Department of Transportation. The paper outlines why the supplier decided to use polyphosphoric acid, experimentation that validated its use, operational and modification tactics, and identifies projects using PPA-modified asphalt with a performance history of up to nine years.
