Bituminous binders constitute 4-7% of the flexible pavements by weight play an important role on structural and functional performance pavements. Traditional hot mix asphalt (HMA) production is done at 150-190 °C that results high-energy usage, smoke odor emission therefore significant cost loss environmental damage. Increasing awareness has questioned whether HMA can be produced lower temperat...

A Life Cycle Assessment (LCA) was undertaken to compare the potential environmental impacts associated with use of Recycled Concrete Aggregate (RCA) as a partial replacement natural aggregates in production Warm Mix Asphalt (WMA), those conventional Hot (HMA). The LCA conducted according ‘cradle-to-laid’ approach, including four pavement phases. Three percentages RCA for coarse WMA were conside...

The adoption of warm mix asphalt (WMA) technologies is well accepted due to its promising environmental benefits, however, their long-term field performance not understood. This study focused on the rutting resistance WMA and companion hot (HMA) based 83 samples collected from 28 projects across United States covering four climate zones, quantified impacts for various as compared HMA. Field cor...

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...
