Cotton Stalk Fiber/Nano-CaCO₃ Composite Modified Asphalt

Aging-resistant, high-temperature rutting-resistant

Exploiting the synergy between cotton stalk fibers and nano-CaCO₃ through physical dispersion and interfacial compatibility, this asphalt forms a stable 3D network that simultaneously enhances high-temperature rutting resistance and anti-aging performance, offering a new route for agricultural waste valorization.
