Rejuvenation of bituminous RAP mastics: an FTIR-based study

This study examines the rejuvenation mechanisms in bituminous RAP mastics using Fourier transform infrared (FTIR) spectroscopy and multivariate discriminant analysis. The chemical interactions between RAP binders, virgin bitumen, warm mix additives, and two commercial rejuvenators (RJs) were evaluat...
