CONT

In building penetration-macadam pavement, a base, usually of crushed stone or gravel, is constructed in layers and firmly compacted by rolling. Often during the rolling, water is applied to make what is termed a water-bound base, or macadam. Then, the keyed and wedged fragments in the upper portion of the base are bonded in place by working alternate applications of bituminous material and choke stone into the surface voids.

CONT

Penetration macadam construction is a surface treatment that is generally regarded as being a more heavy-duty type.
