Warm-Mix Asphalt | E&B Paving

Warm-mix asphalt (WMA) represents a group of technologies that lowers the temperatures at which asphalt pavement material is produced, placed and compacted. This temperature reduction offers several environmental sustainability benefits, including reduced fuel consumption, lower asphalt plant emissions, and the ability to incorporate higher percentages of recycled asphalt product into pavement
