STUDYING THE IMPACT OF NANO-COMPOSITE ON THE PHYSICAL AND MECHANICAL PROPERTIES OF ASPHALT BINDERS.
Modification of asphalt with nanocomposite now it's considered a new approach to improvement of the asphalt characteristics, Chalcogenide d-element it will be used here as an improver to asphalt. The physical and mechanical characteristics of asphalt were examined in this paper, along with comparative rheological testing on binders and mechanical tests for unmodified and modified asphalt with nanocomposite (ZnO/PMMA). In order to increase its performance, a ZnO/PMMA nanocomposite was added to asphalt (60/70) and binders in different amounts (0.2%, 0.4%, 0.6%, 0.8%, and 1%). It was discovered that as the additive hardens the binder, the softening point increases, the binder penetration decreases, the kinematic and absolute viscosities increase, the percentage of stress value increases, and the percentage of strain value decreases. These effects are more noticeable for 0.8% of the nanocomposite. The asphalt resulting from this study is qualified for use in various fields, including paving, concrete, and wide range of applications.
