摘要

Nanomaterials research field has gained prominence in scientific community. The current scenario of exhaustion of sustainable resources and excessive energy usage have impacted the research thrust on potential use of cutting-edge materials and technologies. The current scenario of nanomaterials modified bio asphalt (NMBA) for pavements is reviewed. Firstly, the blends of nanomaterial and bio asphalt studies with their performance aspects are summarized in a methodical manner highlighting the enhancements of conventional properties like penetration, ductility, softening point, viscosity, rheological characteristics namely age, fatigue, high and low temperatures. The outcomes of the review present that nano materials could considerably show improved viscosity, Low & high-temperature property of NMBA. The low temperature of NMBA is marginally reduced in comparison to bio-asphalt without nanoparticles. Additionally, sustainability of biochar modified bitumen is assessed, taking into account its economic viability, environmental impact, life cycle evaluation, and reduction of carbon footprint. Subsequently, potential paths ahead are explored unearthing its prospective applications and future prospects to support safer and sustainable roads. Large scale and real time implementation of such studies would contribute to reducing environmental burden and will pave way for achieving sustainable development goals.
