Physical and Chemical Properties of Nano Zinc Oxide Modified Asphalt Binder

Nanotechnology has recently been applied in various branches of research, including pavement engineering, because the materials it offers are promising and improving. The process modifying asphalt binder developed gradually, now many kinds nanomaterials used. In this study, a flake-structured nano zinc oxide was used as an modifier. At 3%, 5%, 7%, respectively, penetration grade 60/70 binder, modifiers were added. Physical properties modified binders then examined, storage stability, penetration, softening point, viscosity. Meanwhile, chemical property determined using Fourier-Transform Infrared Spectroscopy. It discovered that 3% produced best results. Nano found not to show separation at high temperatures stability test. addition also reduced increased index value indicates treated with is thermally resistant.
