Tertiary flow characteristics of asphalt mixtures
Additional Document Info
A test for permanent deformation evaluation to be used within the Superpave volumetric mixture design procedure was discussed. Two tertiary flow parameters stood out in the study - the flow number of repetitions from a repeated load test, and the flow time from a static creep test. These parameters were found to have excellent correlation with field rut depth. Several concepts such as failure strains, plastic strain ratio, volume change and constant compliance at failure were studied in the testing program.
