Fundamental Properties of Asphalts and Modified Asphalts, Volume 2: Final Report, New Methods
Sixteen new methods that distinguish behavioral characteristics of compositionally diverse petroleum asphalts were developed or refined into new methods during this project. These methods include an automated Heithaus titration (AHT), high performance liquid chromtography/size exclusion chromatography (HPLC/SEC), large scale plant mix simulation (after the German rolling flask method), modulated differential scanning calorimetry (MDSC) to predict low temperature properties, fast ion exchange chromatography, asphalt aging using a microwave oven, non-aqueous potentiometric titration (NAPT) for acids in asphalt, supercritical fluid extraction (SFE) of asphalt concrete cores, a shale oil modified asphalt demonstration site near Jackson, Wyoming, effects of moisture on rheology and aging of asphalt, ion exchange chromatography of asphalts using inexpensive resins, precipitation of waxes from asphalt neutrals, mastics penetration test, fast inverse gas liquid chromatography to predict long term aging, multiple size exclusion chromatography (SEC) to improve definition of associated materials, and a sliding plate microviscometer using aggregate plates to examine thin film behavior.
