Asphalt and the production process. - AlexandriaVA.Gov

2006-5-16  Asphalt and the production process. Hot Mix Asphalt is usually mixed at temperatures between 300 and 325 degrees, and it needs to be laid hot, no less than about 250 degrees. It must therefore be produced close to where it is needed. More than 94 percent of the nation’s two million miles of streets and highways are paved with asphalt.
