How does modification of stone matrix asphalt with nano sio2 impact performance in modified asphalt or bitumen applications?
The modification of stone matrix asphalt (SMA) with nano SiO2 enhances its performance by improving mechanical properties and durability. Nano SiO2 increases the viscosity and elasticity of the asphalt binder, leading to better resistance against deformation and cracking. Additionally, it enhances the adhesion between aggregates and the binder, resulting in improved moisture resistance. Overall, the incorporation of nano SiO2 contributes to a longer service life and better performance of modified asphalt applications.
