Warm-mix asphalt is produced and laid at temperatures that are 50 to 100 degrees lower than those used for traditional hot-mix asphalt. While warm-mix asphalt can lower fuel consumption and emissions, it also enables us to pave in cooler temperatures, extends the paving season into colder months, allows the faster return of traffic to the pavement, and improves the work environment for our employees.

Reclaimed asphalt pavement, which is usually obtained from existing roadways or parking lots, is recycled into new asphalt pavement. This can lower the need for virgin materials by up to 30 percent. Currently, the majority of our asphalt concrete plants are equipped to recycle asphalt.

The asphalt surface is heated and the top layer of asphalt is removed and mixed with a virgin asphalt oil to rejuvenate it. The asphalt blend is then immediately used to repave the road. This process significantly reduces the amount of material hauled to and from the site.

The full-depth reclamation process, which takes place at the site, entails recycling existing asphalt pavement and the underlying roadbed into a high-quality base material, over which we lay new or recycled asphalt.
