CHANGES IN ASPHALT CONCRETE MIXTURE PROPERTIES AS AFFECTED BY ABSORPTION, HARDENING, AND TEMPERATURE

This paper provides information on the split cylinder testing of laboratory-compacted specimens and cores taken from in-service pavements. Tension test data were obtained for mixtures containing different aggregates, asphalt contents, types of asphalt, and temperatures. Relations between energy and vertical and horizontal deformations were developed from the test data. It was observed that energy decreased at lower temperatures. The horizontal and vertical deformations as measured in the split cylinder test were found to be related to the viscosity of the asphalts as influenced by hardening and temperature. This could be significant because it may provide a method to evaluate the composite effects of asphalt-aggregate interaction for use in quality control of asphalt paving mixtures. Further information is provided on penetration-viscosity relations and the properties of the materials used in the investigation.
