Abstract

The high volume of water in molasses has made this study serious. The reason is that using molasses as a partial replacement without treatment significantly affects the rheological properties of the neat bitumen and increases the likelihood of moisture susceptibility of the hot-mix asphalt (HMA) pavement structure and create fractures of aggregate particles. Therefore, to use molasses as a partial replacement without affecting the structural integrity of the pavement, this study proposed a treatment method before blending it with bitumen. The main objective of this study is to investigate the effect and the potential of using molasses as a modifier for neat bitumen using chemical and rheological approach. The control binder was a performance grade (PG58-10) petroleum-based neat asphalt binder. A series of experiment was conducted to accomplish the objective of this paper, including convectional tests, Fourier transform infrared (FTIR) test, amplitude and frequency sweep test, performa
