Effect of Oxygen Pressure on Asphalt Oxidation Kinetics ...

2000-1-29 · The oxidation of asphalt is a major cause of pavement failure. At a given temperature and pressure, the asphalt oxidizes in two stages: (1) a rapid-rate period followed by (2) a long period with constant oxidation rate. The degree of oxidation that occurs in the constant-oxidation region is asphalt-dependent and varies with oxygen pressure and with temperature. Using pavement-temperature ...
