Adhesion quality and rheological properties of unmodified and nano-modified asphalt residues derived from paving-heavy crude oils

The paving-heavy crude oils (PHCO) are natural cut-back asphalts that can be used for unconventional paving solutions for low- and medium-traffic roads given their lower cost in comparison with conventional asphalt binders (i.e., produced through industrial oil refining). Despite their potential, th...
