Effect of Dissolved Species from Crumb-rubber Modifier on Micromechanical Properties of Asphalt Binder

摘要: This study presents a correlation between the crumb-rubber modifier's (CRM) released components into crumb-rubber-modified asphalt (CRMA) and developed micro-mechanical properties of thin layer. simulates behavior layers formed around aggregate during mixing hot-mix (HMA). provides link modified asphalt's change in intrinsic materials (elastic modulus hardness) CRM components. The dissolution component release were calculated by performing tests thermo-gravimetric analysis (TGA) on extracted particles after interaction with asphalt. utilization TGA confirmed that CRMA's hardness elastic was dependant and/or It found enhancement CRMA micromechanical is attributable to most natural synthetic rubber under specific conditions. At early stage time, minimal results minor modulus. Upon increase time (up 8 hours), major observed as result
