Accelerated Loading Performance and Laboratory Characterization of Crumb Rubber Asphalt Pavements
This paper presents the findings of laboratory characterization and field performance evaluation of crumb rubber modified (CRM) asphalt pavements. In this study, a wet process (Wet Rouse) asphalt rubber was used as CRM. Laboratory mixture characterization included the indirect tensile strength (ITS), indirect tensile resilient modulus (MR), indirect tensile creep test, axial creep test, Superpave frequency sweep at constant height (FSCH), simple shear at constant height (SSCH), and repetitive shear at constant height (RSCH) tests. Field accelerated loading (ALF) evaluation included the performance comparison of three different pavement designs that included: 1: conventional structure (no CRM), 2: CRM in the wearing course mix, and 3: CRM in the base course mix. Based on the results of this study, the authors concluded that CRM asphalt mixtures and conventional mixes behaved very similarly in their laboratory characterization. ALF test lane contained CRM asphalt mixtures at base course exhibited significantly smaller rut depth than the test lane containing conventional mixtures, whereas, test lane with CRM mix at surface wearing course had similar rut depth as the lane with conventional mixes.
