Determination of the Presence of Antistripping Agents in Asphalt Cement by High-Performance Liquid Chromatography

Source

Chemical agents are often introduced into asphalt for the purpose of influencing the performance of bituminous concrete. The presence of these added chemicals can serve to complicate already difficult methods for asphalt compositional analysis. A description of high performance liquid chromatography (HPLC) techniques that aid in identifying antistripping additives in asphalt is presented. The method is sensitive to both the additive and the asphalt. The utility of HPLC as a probe in investigating the effects of thermal conditioning on asphalt/additive combinations is demonstrated.
