The rheological and chemical properties of hydrated lime-polyphosphoric acid (PPA)–modified asphalt binders before and after laboratory oxidative aging were investigated through dynamic shear rheometer (DSR) and nuclear magnetic resonance (NMR) tes

Extensive research has been performed to determine the relationship between polyphosphoric acid (PPA) and hydrated lime in bitumen pavement mixes, but the fate of PPA in the paved road has not been determined. Perhaps as important, the mechanism of s

Phosphorous-31 NMR spectroscopy has been used to study the effect of hydrated lime and limestone fines on polyphosphoric acid (PPA)-modified bitumens. NMR spectra were acquired on bitumen samples that were first modified with PPA and on bitumen sampl

An experiment involving three neat asphalts and their mixtures with 1.5 wt % of polyphosphoric acid (105%) was conducted to investigate the effect of polyphosphoric acid (PPA) on the long-term aging characteristics of asphalt binders. Analytical tech

Phosphorous-31 NMR spectroscopy has been used to study the behavior of polyphosphoric acid (PPA) in bitumen. Phosphorous NMR spectra were acquired on a PPA-modified bitumen immediately after blending, and on samples that were stored at 135°C for dif

New coking indexes were developed to measure how near a pyrolysis system is to coke formation during the coke formation induction period. These are based on an asphaltene flocculation titration and the cyclohexane soluble portion of heptane asphalten
