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 recycling of hot-mix asphalt pavements containing a crumb rubber modifier (CRM) has been an area of interest since CRM was first used in asphalt paving materials over

Abstract: The warm-mix asphalt (WMA) refers to technologies that allow a significant reduction of mixing and compaction temperatures of asphalt mixes through lowering the viscosity of asphalt binders. Several studies have been carried ...

Abstract: The recycling of reclaimed asphalt pavement (RAP) is typically achieved by adding a rejuvenating agent into the mix. The addition of the rejuvenating agent leads to adjusting the compositions and consequently improving the ...

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: In this paper, the micromorphology of asphalt binders with wax warm additives is investigated by atomic force microscopy (AFM) and optical microscopy before and after aging. Performance grade (PG) 64-22 asphalt binder is ...

Abstract: Crack sealing and crack filling treatments have always been an important consideration to prolong the life of pavement among all pavement maintenance programs. Crack sealing uses a router to cut the crack to provide a ...

Abstract: The performance properties of rubberized asphalt binders at high, intermediate, and low temperatures were evaluated as a function of Fischer–Tropsch (FT)–paraffin wax content. The rubberized binders were blended using five ...

Abstract: The compaction conditions (e.g., compaction temperature and compaction level) of crumb rubber modified (CRM) asphalt mixtures should be determined carefully because the viscosity and amount of the CRM binder affects the ...

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) ...
