Abstract: In this paper, various Atomic Force Microscopy (AFM) techniques are utilized to study the effects of different warm mix asphalt (WMA) additives on the nanostructure and microstructure as well as the adhesive and cohesive ...

Abstract: Warm mix asphalt (WMA) has received considerable attention in the past few years to reduce energy consumption and pollutant emissions during hot mix asphalt (HMA) production and placement. However, many concerns and questions ...

Abstract: In recent years, a new group of technologies has been introduced in the United States that allow producing asphalt mixtures at temperatures 30 to 100°F (16.7–55.6°C) lower than what is used in traditional hot-mix asphalt ...
