Impact of incorporated gamma irradiated crumb rubber on the short-term aging resistance and rheological properties of asphalt binder
Graphical abstract FTIR spectra of CR and CR irradiated at 300kGy. Display Omitted
Highlights The objective was to study the effects of irradiated crumb rubber on asphalet binder. The results showed that the asphalet binder is influenced by the irradiated dose. CR irradiated at 300kGy modified the penetration, softening point, ductility. CR irradiated at 100 and 200kGy modified asphalt was impaired more heavily.
Abstract In this new study, the effect of gamma irradiation on the waste tire rubber for its using as modified asphalt binder was elaborated. The study was initiated to investigate the anti-aging performance and rheological properties of asphalt modified crumb rubber impregnated. In this context, three samples of crumb rubber (CR) obtained from waste tire were irradiated by gamma at 100, 200 and 300kGy and used with two different percentages 5% and 10%, by mass of total asphalt binder. The modified asphalt binders (CRM) were evaluated from the perspective rolling thin film oven method (RTFO) and Brook field viscosity. The results showed that using 10% of CR subjected to gamma rays at 300kGy with asphalt had high temperature stability, low temperature ductility and anti-aging performance. Also the rheological studies illustrated that the modified asphalt binder contains CR irradiated at 300kGy have the largest adsorption of the asphalt molecules.
