Abstract

This project examined asphalt-based, bio-based, and coal-tar-based rejuvenators to determine rejuvenator effectiveness and the concentrations of polycyclic aromatic hydrocarbons (PAHs) in particulate material detached from pavement surfaces treated with each rejuvenator. Through testing using a Model Mobile Load Simulator and Gas Chromatography analysis, we observed that rejuvenators qualitatively appeared to improve pavement surface appearance, and determined PAHs were present in particulate material detached from pavement samples treated with the rejuvenators. Based on our results, we recommend the use of bio-based rejuvenators because of the improvement in surface appearance and the low levels of PAHs in detached material.
