Rheological and Compressive Strength Characteristics of Laboratory and Field Compacted Asphaltic Concrete Mixtures
A quantitative analysis was made of the effect of length-to-diameter ratio on the ultimate unconfined compressive strength, the axial and transverse elastic properties, and the rheological creep and dynamic strength characteristics of laboratory compacted asphaltic concrete test specimens and field core test samples. The field and laboratory compacted test specimen data have indicated that the application of the linear viscoelastic theory and mechanistic models to asphaltic concrete are valid, as well as the time-temperature superposition concept and the analogous time-L/D ratio equivalency principle are valid for the research data obtained on the phenomenological level. Long-term creep experiments up to forty hours have provided an additional and independent check of the concepts developed and employed in this research. A significant difference in the mechanical properties of comparable laboratory and field compacted test samples was noted for all the strength parameters investigated. (Author)
