NRRA: Long-term Testing and Analysis on Asphalt Mix Rejuvenator Field Sections

Status:  Active
Project Start Date:  08/24/2020

Summary:

The objective of this research project is to evaluate the effectiveness of seven RA products over time and evaluate their performance as compared to the control mixtures. This will be accomplished through a combination of binder and mixture characterization and performance testing using different laboratory aging levels, field core testing, and performance monitoring of field test sections over time. The outcome of this project is anticipated to provide NRRA with guidelines for assessment and adoption of RAs for routine usage in asphalt mixtures.
