and Field Performance of Warm Mix Asphalt Technologies CHAPTER 1 BACKGROUND Research Problem Statement Hot mix asphalt (HMA) is produced at temperatures between 138°C (280°F) and 160°C (320°F). These temperatures ensure that the aggregate is dry Finland and asphalt cement which is then heated before being applied. This is usually used by heating the asphalt mix up to 300-500 degrees at the production facility before being shipped and laid at the target location.versus warm-mix asphalt versus even cold-mix asphalt which traditionally is being used in maintenance area and pothole patching and things of that nature.
