BASE

Material installed prior to asphalt paving.  May be a crushed stone product or asphalt product (see full-depth asphalt pavement).  The base material provides the load bearing characteristics of the finished pavement and may vary from 3-4” for a residential driveway to 18” or more for parking areas or roadways.  The correct type and amount of base material must be determined and specified prior to paving.  Lack of adequate base material is a primary cause of pavement failure.
