FURTHER STUDIES OF MASS VISCOSITY BY A MODIFIED STRESS RELAXATION METHOD

THE RELATIONSHIP BETWEEN COMPACTION BEHAVIOR AND ASPHALT VISCOSITY IN BITUMINOUS CONCRETE IS OF INTEREST. ONE WAY TO EXPLORE THIS IS TO STUDY ASPHALT VISCOSITY INFLUENCES ON THE MASS VISCOSITY-TEMPERATURE CHARACTERISTICS OF THE MIX. AN EXPERIMENTAL METHOD FOR THE LATTER HAS BEEN INVESTIGATED. IT USES A SERIES OF CONSTANT-RATE-DEFORMATION-AT-CONSTANT- LOAD FLOW PERIODS SEPARATED BY INTERVALS OF STRESS RELAXATION. RESULTS OF SUCH TESTS CAN BE ANALYZED IN TERMS OF COMPONENT CONTRIBUTIONS FROM THE MIX SYSTEM, REPRESENTED BY A MODEL CONTAINING AN ELASTIC SPRING, A DASHPOT AND A PLASTIC YIELD MECHANISM. LINEAR VISCOELASTIC TECHNIQUES DO NOT APPEAR SUITABLE. THE DIRECTION OF FUTURE WORK IS OUTLINED. /AUTHOR/
