Abstract

The objective of this research is to evaluate the resilient modulus of using granular Buton rock asphalt (BRA) modifier binder for modified asphalt mixtures based on the developed resilient modulus master curve. In this research, indirect tensile stiffness modulus tests were conducted on unmodified and BRA modified asphalt mixtures for dense graded aggregates of 10 mm, using UTM25 machine. A twenty percent of BRA natural binder by total weight of asphalt binder was chosen as a substitute for the base asphalt binder in the BRA modified asphalt mixtures. The unmodified and BRA modified were tested under different condition of temperatures and frequencies to develop resilient modulus master curve. The results of investigation indicated that asphalt mixtures modified by granular BRA additives had higher resilient modulus than unmodified mixtures in the high-intermediate temperature range and low frequency, therefore the viscoelastic behavior of BRA modified was higher than for unmodified asphalt mixtures.
