Abstract:
As the demand for sustainable and eco-friendly construction materials continues to grow, this study explores an innovative approach to improving both the environmental footprint and durability of road infrastructure. Specifically, it investigates how combining Recycled Asphalt Pavement (RAP) with bio-based additives like algae and starch can create more resilient and sustainable bituminous mixes. RAP, which contains aged aggregates and binders reclaimed from existing asphalt layers, offers a promising alternative to virgin materials but often suffers from reduced flexibility and bonding capability. To address these issues, renewable additives are introduced—algae for its plasticizing effects and starch for its strength-enhancing properties. Through a series of laboratory tests, the research examines how these materials impact the physical, chemical, and mechanical performance of the mix, focusing on key factors such as stiffness, rutting resistance, fatigue life, and moisture susceptibility. Beyond performance, the study highlights significant environmental and economic benefits: reducing construction waste, conserving natural resources, lowering carbon emissions, and cutting material costs. Ultimately, this work aims to offer a practical, cost-effective, and sustainable solution for modern pavement construction, bridging the gap between engineering needs and environmental responsibility.
