Warm mix asphalt for cold weather condition

ABSTRACT Improved environmental responsiveness and stricter emission policy have led to a growth of warm mix asphalt (WMA) to reduce the high mixing temperatures of regular hot mix asphalt (HMA). Its benefits are reduction in energy consumption during production and reduced emissions during production. All methods reduce the viscosity of the binder at a sure temperature range, allowing the aggregate to be fully coated at lower temperatures than in HMA production. These are mentioned below. ? The possibility of placement at a lower temperature. Important when there are long haul Distances. ? Reduction in energy consumption and lower emissions. ? Reduction in energy consumption and environmental factors. ? Reduction in energy consumption during production is a factor that will be use to evaluate the advantage of WMA if it will lower the overall cost of a project. ? Reduction in energy consumption because of lesser temperatures, longer paving period and lesser environmental impact of production and placement in urban areas.
