Effect of aging on the chemical, morphological and wettability characteristics of polyurethane modified binder

Aging of asphalt binders occurs when oxidation takes place in the binder, and this in turn causes the deterioration of pavement. This paper presents the effect of aging on 60/70 penetration grade asphalt binder incorporated with polyurethane (PU) in terms of chemical interaction, morphological and w...
