ASPHALT BINDER

The asphalt layer between the base layer of rock or other aggregate and the driving surface layer.  The asphalt binder layer is usually made up of coarser materials and is usually thicker than the surface layer.  The binder layer can be used as either a first layer or a driving surface, but its use is actually fairly limited.  The vast majority of jobs call for a stone base layer, an asphalt base layer, and a surface layer.
