Asphalt modification is one of the best methods for enhancing the performance and longevity of flexible pavements that are subjected to high traffic volumes and varied climatic changes. Due to the potential of enhancing asphalt performance and having zero environmental footprint, bio-modifiers received wide attention globally. As a bio-based asphalt modifier, Rice Husk Ash (RHA), a large-scale by-product of rice manufacturing, was found to be a promising candidate. The production process of RHA Modified Asphalt (RMA) is a crucial stage for the development of a better-performing modified asphalt and depends on the blending parameters considered. Therefore, the objective of this research work was to investigate the effect of blending parameters on the temperature susceptibility of RMA based on the laboratory experiment results and a comprehensive statistical analysis. The blending parameters considered are RHA dosage, blending duration, blending temperature, and shear rate. In order to arrive at the objective, this study initially investigated the interaction between asphalt and RHA using Fourier Transform Infrared Spectroscopy. Further, the storage stability and consistency characteristics of RMA were evaluated at different levels of blending parameters. Consistency test results were used to develop Viscosity Temperature Susceptibility (VTS) plots. Statistical analysis was conducted to determine the impact of each blending parameter on the VTS. The research results showcased that the VTS of RMA is significantly influenced by the individual blending parameters and their interaction effects. Overall, it can be concluded that blending parameters play a vital role in the reduction of temperature susceptibility of RMA.
