Abstract Despite significant economic and environmental benefits, performance of warm mix asphalt (WMA) containing reclaimed pavement (RAP) remains a matter concern. Among the current WMA technologies, plant foaming technique (called “foamed WMA” in this study) has gained most attention, since it eliminates need for chemical additives. In present study, laboratory performance, namely rutting mo...

This study quantifies the potential environmental benefits associated with incorporation of industrial by-products and recycled materials combined warm mix asphalt (WMA) additives in wearing course mixtures for pavement construction. An electric arc furnace (EAF) steel slag-based three incorporating slag fractionated reclaimed (RA) varying contents (i.e. 25, 40, 50%) were analyzed comparatively...

Abstract Crumb rubber (CR) is generated from the recycling of used or discarded car tires and has long been utilized in paving industry. can be asphalt mixes two ways: dry process wet process. However, compared to standard combinations, crumb modified (CRMA) requires much higher mixing compaction temperatures. As a potential substitute, using warm mix (WMA) technology significantly lower hot-mi...
