Brief Review of the Chemistry of Polyphosphoric Acid (PPA) and Bitumen

Bitumen finds great use in paving and roofing applications. To enhance or extend its performance, it is often modified with a polymer, including polyphosphoric acid (PPA). PPA is a reactive oligomer, a short-chain polymer, whose reaction with bitumen is poorly understood. In an effort to better unde...
