Method & Evidence

AimHow can surface modification of recycled polyester fibers with nano-silica improve their thermal resistance and performance in asphalt mixtures?

MethodExperimental Research

ProcedureRecycled polyester fibers (Re-PET) were modified by grafting nano-silica onto their surface to create a new hybrid material (SiO2/Re-PET). The morphology and thermal properties of the modified fibers were analyzed. Subsequently, asphalt mastics and mixtures were prepared using both Re-PET and SiO2/Re-PET, and their rheological and pavement performance characteristics were evaluated and compared.
