Analysis of Chemical Modification Mechanism and Rheological Properties of Polyphosphoric Acid Modified Asphalt

In order to study the chemical modification mechanism and rheological properties of polyphosphoric acid (PPA) -modified asphalt, asphalt modified with different PPA contents were characterized by four-component test, atomic force microscopy (AFM) and Fourier transform infrared spectroscopy (FTIR). I...
