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...

This study made comparisons of the expected noise and durability performance of asphalt surface mixes based on laboratory testing only, and recommended a set of surface mixes for field test sections with improved surface performance properties. The study included a series of experiments to investigate the effects of several important mix variables identified in studies of field test sections, i...

Evaluating the performance of rejuvenated asphalt mixes is crucial for pavement design and construction, as using a rejuvenator not only boosts recycling contributes to positive effects on environment but also increases sensitivity rutting moisture. This study was executed evaluate effect warm mix (WMA) antistripping agent, namely nano-ZycoTherm, moisture-induced damage potential mixtures conta...

This report presents the comparative life cycle assessment (LCA) between warm stone mastic asphalt (SMA) and conventional SMA. Specifically, the study evaluated and compared the life cycle environmental and economic performances of two mixtures: a warm SMA binder course mixture with a chemical additive and a control hot SMA binder course mixture. Both of these mixtures were utilized as part of ...
