Construction. In order for traditional asphalt to be used, it must first be heated to 250 to 350 degrees Fahrenheit so that asphalt is softened. At these temperatures asphalt is fluid and will bond with the surface if it is applied. A tack layer of asphalt should be put on pavement to make sure that there is a strong bonding between the layers.
