Check Mix Design for Warm-Mix Asphalt in the Lab

The Foamer is designed to give repeatable foamed asphalt samples that are used for WMA mix designs in the lab. Even though it’s a “warm-mix” device, it has multiple heated surfaces. The lab tech must remember his or her safety practices around this machine, and never touch the inside reservoir or exit tube when the unit is heated.
