Incorporating date seed powder (DSP) into asphalt binder: A feasibility study on sustainable and economical practices in Saudi Arabia

This research investigates the potential use of Date Seed Powder (DSP) as a sustainable modifier for asphalt binders in Saudi Arabia. Date seeds, a readily available byproduct of the date fruit industry, offer a promising alternative to traditional asphalt modifiers, promoting a circular economy and reducing reliance on non-renewable resources. The study proposes incorporating DSP into asphalt binders to enhance their performance and durability, particularly under extreme climatic conditions and heavy traffic loads. The research explores the advantages of using DSP, including its unique chemical composition, cost-effectiveness, and environmental benefits. The study outlines methods for collecting and preparing DSP, and discusses the environmental impact of date seed disposal. It also highlights the sustainability aspects and contribution of this approach to Saudi Arabia's Vision 2030. The research concludes that using DSP as a binder modifier offers a promising solution for improving the durability and lifespan of roads in Saudi Arabia, contributing to a more sustainable and cost-effective infrastructure.
