- W1510822023 abstract "This paper documents and discusses the development of instrumented micro-indentation tests for the specification grading of asphalt cements. Seven recovered asphalts from a northern Ontario trial were tested with a flat-ended punch indenter in both static creep and dynamic oscillatory tests on thin films at low temperatures. The rheological properties determined included: creep stiffness and slope of the creep stiffness master curve (S and m-value); elastic/total work of indentation (We/Wt); elastic recovery (ER); viscous creep compliance (Jv); dynamic storage, loss and complex moduli (E’, E”, and E*); and dynamic phase angle (delta). Dynamic tests were generally found to be more reproducible than static (creep) tests, probably due to the intricacies in contact detection for the latter. Indentation creep stiffness, viscous creep compliance, and phase angle correlated well with pavement performance. Previous investigations revealed that creep properties determined on rolling thin film oven/pressure aging vessel (RTFO/PAV) residues for these sections failed to show any correlation with performance. This is likely due in part to the unrealistic film thicknesses of 1.2 and 3.2 mm and temperatures of 163 and 100°C employed in RTFO and PAV aging methods. Another look at thin film aging protocols is warranted since thinner films should allow us to age the asphalt cement more realistically at lower temperatures and pressures. More accurate asphalt aging and conditioning protocols combined with the newly developed indentation tests will allow us to reliably and precisely select asphalt cements to ensure their maximum durability." @default.
