• Abstract:
  The objective of this research was to investigate paving asphalts used by the Texas Highway Department to determine how they can be evaluated for quality and their durabilities improved. A number of representative paving asphalts were analyzed by (1) a modified Traxler and Schweyer Component Analysis procedure using pentane, butanol and acetone; (2) a modified Pitchford and Axe method using pentane, isopropanol and acetone; and (3) the Rostler analytical procedure using pentane, 85%, 98%, and fuming sulfuric acid. The data obtained were correlated with oxidation of 15-micron films of each asphalt for 2 hours in a dark oven at 225°F, and in some cases with photooxidation of 15-micron films under radiation from a 175-Watt Mazda Sunlamp for 2 hours at 190°F. Changes in composition caused by oxidation were determined.
