Abstract
The investigation reported herein concerns the changes which have occurred in asphalt cements recovered from test roads during six years of service. Results of standardized tests and special tests performed on the asphalts are shown to compare the initial properties of the asphalts with Subsequent changes in physical and chemical properties. Different testing instruments and methods were used to determine their desirability for evaluating fundamental and empirical properties of the asphalts used in the teat roads. The trend of changes in asphalt occurring with age is presented and tentative recommendations are suggested for the specification of asphalts in order to improve or to make better use of certain fundamental properties of asphalts.|This constitutes the final report of a cooperative study with the Texas Highway Department. Earlier progress reports on this research have been presented to the Texas Highway Department.
