When asphalt is mixed at the plant, it is super heated to in excess of 325° F. By the time it is put in a truck, shipped to the job site and installed on your project, it should still be a minimum of 250° to allow it to be properly compacted. Ambient air temperature and the temperature of the ground both play a significant role in how long the asphalt is ‘workable’ and can be properly compacted. This can range from several hours on a hot summer day to 10 minutes on a chilly fall morning.
