Abstract

Every year, during energy production, a large amount of agricultural waste is generated as ash, such as husks from rice and wheat. The conventional practices of open dumping and landfilling of this ash cause severe environmental and health problems, particularly groundwater contamination. Moreover, a lack of space for further dumping or landfilling worsens the situation. Considering the difficulty of its disposal, as a solution, this research uses two different agricultural waste ash to improve the asphalt binder engineering properties. The study evaluates the optimum dosages of agricultural waste and assesses the economic benefits of using such modified bitumen in road construction. By integrating waste technology, this project proposes an innovative approach to enhance bitumen’s conventional properties, durability, and sustainability in road construction. The investigation demonstrates that increasing the rice husk or wheat straw percentage in bitumen decreases its penetration value. However, the penetration value approaches the base bitumen when both waste materials are used together. The modified bitumen also exhibits higher softening points, making it suitable for higher temperature zones. Ductility decreases with the inclusion of agricultural waste, indicating that neat bitumen is better suited for high-temperature zones, while modified bitumen may be advantageous in low-temperature zones. The study emphasizes carefully selecting waste percentages to achieve desired bitumen properties. Future research should focus on optimizing the waste material mixture, conducting life cycle assessments, exploring large-scale implementation, and collaborating with industry stakeholders and policymakers to promote sustainable road construction practices.
