A methodology for studying the relationships between fracture behavior and morphology of polymer-modified asphalts used as binders was developed by using the linear elastic fracture mechanics (LEFM) method and confocal laser scanning and environmental and cryo-scanning electron microscopies. Different types of polymers were used as modifiers: (i) copolymers from ethylene and methyl acrylate (EMA),...
Asphalt cements (vacuum residues of petroleum) used as binders for road construction can undergo weathering phenomena or natural oxidation to various degrees depending on their chemical structures and on their origin. The first aim of this study was to determine the characteristics of the source rocks generating the parent crude oils. The second aim was to correlate the chemical structures of recovered...
