Evaluation of Crumb Rubber Modification of Louisiana Mixtures

The objective of this research is to evaluate the effect of using crumb rubber modification (CRM) on Louisiana asphalt mixtures. The evaluation will include impacts of modification on design volumetric, loaded wheel testers (LWT) performance, and semi-circular bending (SCB) performance. Dense graded and gap graded mixtures will be evaluated. This research will also evaluate potential methods for quality control/quality assurance (QC/QA) of binders modified with crumb rubber. The binder evaluation will include standard Strategic Highway Research Program (SHRP) Superpave Rheometer testing, chemical evaluation, and extraction.
