| description abstract | In this study, the effects of two nanomaterials—nanoclay and nano hydrated lime—on the fatigue properties of bitumen were investigated. Nano hydrated lime was produced in a laboratory using a planetary ball mill. The milling process was conducted in the specified conditions of speed, time of rotation, and ball to powder ratio (BPR). The processing conditions were determined by a trial and error procedure. With the aim of evaluating the fatigue life of modified mixes, various filler-bitumen combinations were tested under linear amplitude sweep (LAS) testing, which was performed using a dynamic shear rheometer (DSR) instrument. The results indicated that nanoclay at 6% level (by weight of bitumen) increased fatigue life of the binder by approximately 40%. The specimen that contained 10% nano hydrated lime showed the fatigue life that was 49% greater than that containing 10% hydrated lime. Based on the results of this research, 6% nanoclay and 5% nano hydrated lime were the optimum amounts of these materials to be added to bitumen for nanomodification purposes. | |
