Abstract

The objective of this research was to evaluate the impact of using granular Buton Rock Asphalt (BRA) modifier binder in asphalt mixtures, based on the developed resilient modulus master curve. This involved laboratory evaluation of indirect tensile stiffness modulus (ITSM) on UTM25 test equipment in accordance with the Australian Standard AS2891.13.1-1995. The test was applied to dense-graded (10 mm) unmodified and BRA-modified asphalt mixtures at five different test temperatures: 5°C, 15°C, 25°C, 40°C and 60°C and three different loading frequencies: 0.33 Hz, 0.50 Hz and 1.0 Hz. The results showed that in the high-intermediate temperature range and at low frequency the resilient modulus of BRA-modified asphalt mixtures was higher than the modulus of unmodified mixtures. It was discovered that the viscoelastic behavior of BRA-modified asphalt mixtures was more pronounced than in the case of unmodified asphalt mixtures
