Synthesis and Evaluation of Cadmium Sulfide/Polymethylmethacrylate Nanocomposite and Their Effect on Physical and Mechanical Properties of Asphalt Pinder

ABSTRACT In this work, comparative rheological tests on binders and mechanical tests for unmodified and modified asphalt with a nanocomposite (CdS–polymethylmethyacrylate [PMMA]) were carried out, and the physical and mechanical properties of asphalt were studied. Asphalt (60/70) and binders were modified with a CdS–PMMA nanocomposite to improve its performance in various percentages, 0.2, 0.4, 0.6, 0.8, and 1%. An increase in the softening point, decrease in binder penetration as the additive hardened the binder, increase in kinematic viscosity, increase in absolute viscosity, increase in the percentage stress value, as well as decrease in the percentage strain value were found, which appears that the 0.8% has the better character from the nanocomposite.
