Mechanism behind Time Dependent Elasticity of Crumb Rubber-Nano-Asphalt Hybrids Using Discrete Relaxation Spectrum

Crumb rubber powder is a successfully used renewable material obtained from waste tire rubber, which has been incorporated into paving asphalt since the 1930s due to its good resistance deformation and fatigue as well eco-friendly performance. In this study, carbon nanotubes nano silica were terminal blend crumb modified technology remedy issues of excessive desulfurization degradation ground tyre with technology. The mechanism behind high temperature delayed elastic properties rubber-nano-asphalt hybrids was experimentally investigated based on discrete relaxation spectrum. Development spectra accomplished by fitting 60°C storage modulus data tested dynamic shear rheometer using generalized Maxwell model. Subsequently, feasibility characterizing elasticity main time verified test results creep recovery test. Results indicated that exhibited arrheodictic behavior strengthened two agents. Moreover, reinforcement greater than silica. Additionally, correlation observed between zero viscosity time, correlated longer times. Furthermore, related average rate in This research expected shed some light time-dependent perspective polymer physics.
