SHRP core asphalts, their acid-base fractions, and laboratory-oxidized counterparts were analyzed. Based on the concept that molecular size distribution and the molecules' ability to assemble into larger entities in solution and into networks in neat asphalt are crucial to the performance of the asphalt. Attributes of the network formed will determine the asphalt's ability to resist thermal shock, for example, by providing strength and elasticity.Explores the use of high performance gel permeation chromatography as a means of studying asphalt composition and intermolecular interaction.
