Abstract EN
This paper evaluates the effect of polymer enhancement with antioxidant in the rheological properties of bitumen and mechanical properties of bituminous concrete mixture (BCM).
In this study, two antioxidant-enhanced polymers were utilized in mitigating bitumen hardening due to aging.
The rheological testing consists of temperature sweep using Dynamic Shear Rheometer at various aging conditions.
Critical stiffness temperature data from the sweep test suggested that enhanced polymer exhibits less long-term hardening and brittleness compared to standard polymer.
The mechanical testing consists of dynamic modulus, indirect tensile, flow number, and beam fatigue tests on BCM exposed to short-term aging.
Hamburg wheel tracking test was also performed to assess moisture-damage susceptibility.
It is found that the enhanced-polymer BCM exhibited higher modulus, higher tensile strength ratio, improved rutting resistance, lower moisture-damage susceptibility, and slightly increased fatigue life as compared to standard-polymer BCM.
