Box Behnken Design in Optimizing the Sustainability of Sasobit-Based Warm Mix Asphalt Concrete
By Ogani F.U., Ohwerhi, K.E., Eme, D.B., Nwaobakata C.This study evaluates the sustainability of Sasobit-based warm mix asphalt concrete (WMA) in comparison to traditional hot mix asphalt (HMA). A comprehensive sustainability assessment was conducted using life cycle assessment (LCA) and life cycle cost analysis (LCCA). The results show that Sasobit-based WMA reduces greenhouse gas emissions, energy consumption, and environmental impacts compared to HMA. Additionally, the LCCA reveals that Sasobit-based WMA has a lower life cycle cost than HMA. The findings of this study suggest that Sasobit-based WMA is a more sustainable option for pavement construction and rehabilitation. The results of this study can inform pavement design and construction practices, promoting the adoption of more sustainable asphalt technologies.
