RHEOLOGICAL ASPECTS OF AGING: PART II
THE EFFECT OF AGING OF THE ASPHALTIC BINDER ON THE RHEOLOGICAL RESPONSE OF SAND-ASPHALT MIXTURES IS STUDIED. THE EXPERIMENT AND THE METHOD OF ANALYSIS FOLLOW PROCEDURES OUTLINED IN AN EARLIER REPORT. THE CREEP RESPONSE OF SAND- ASPHALTS AT VARIOUS TEMPERATURES AND AGING HAVE BEEN ANALYZED, AND THE VISCOELASTIC MODEL PARAMETER AND OVERALL RESPONSE HAVE BEEN RELATED TO THE ASPHALT AGING INDEX. DIFFERENCES ARE SHOWN IN THE AGING SUSCEPTIBILITY OF MIXTURES PREPARED WITH DIFFERENT ASPHALTS. EXPRESSIONS ARE PRESENTED TO SHOW THE EFFECT OF ASPHALT AGING INDEX ON THE VISCOELASTIC MODEL PARAMETER AT VARIOUS TEST TEMPERATURES. ANALYSIS OF ACTIVATION ENERGY HAS BEEN CARRIED OUT THAT SHOWS THAT THERE ARE CERTAIN LIMITATIONS IN USING THE ACTIVATION ENERGY CONCEPT IN THE STUDY OF AGING. /AUTHOR/
