Abstract: The phase separation between polymer additives and virgin asphalt binders during hot storage is an important issue in the asphalt industry. Traditionally, it has been customary to evaluate the degree of phase separations ...

Abstract: The objective of the study in this paper was to investigate the influence of warm mix additives on polymer-modified asphalt (PMA) mixtures in regards to engineering properties. Twelve PMA mixtures (four control PMA mixtures ...

Abstract: This research investigates the oxidative aging levels of polymer-modified asphalt (PMA) mixes using gel permeable chromatography (GPC), which can help to simplify the quantification of asphalt aging. Warm-mix asphalt (WMA) ...
