Zusammenfassung:This study characterizes the interaction of asphalt cement with ground tire rubber (GTR) using rheological tests, chemical characterization tests, settling and rubber dissolution tests. Curing time and temperature, mixing rate, rubber mesh size are important factors that affect the rubber depolymerization rate. The obtained high cure asphalt-rubber binders are homogeneous, compatible and have non-detrimental viscosity at hot-mix temperatures, while still being viscous and elastic at rutting temperatures and less stiff at cold temperatures than base asphalt.
