Title: Why and How of Polyphosphoric Acid Modification: An Industry Perspective
Accession Number: 01363327
Record Type: Component
Availability: Find a library where document is available Abstract: Evolution of asphalt binder specifications continually challenges asphalt practioners to seek tools allowing production of binders from most readily available materials. These tools must facilitate production of asphalt binders that not only meet existing specifications, but ensure long-term performance. Polyphosphoric acid (PPA) is just one such tool. This paper discusses common asphalt binder specifications, the relationship of asphalt binder chemical composition to performance grade (PG) properties of asphalt binders, necessary use of PPA modification to meet specifications, the relationship of asphalt composition to PPA loadings necessary to achieve desired properties, expected PG enhancements of PPA-modified asphalt binders, and the effects of using PPA in nonpolymer- and polymer-modified asphalt binders to meet current PG specifications.
