Evaluation of modified binders and mixes with warm mix asphalt wma additives

Abstract

Warm mix asphalt WMA refers to the technologies meant for significantly reducing the mixing and compaction temperatures collectively referred as production temperatures of asphalt mixtures and hence have the main advantages of cutting fuel consumption and decreasing the emissions of greenhouse gases Meanwhile the benefits of modified asphalt binders to cater for increasing traffic severe axle loads and unanticipated variations in pavement temperatures are increasingly being recognized
