Description
This technical paper provides guidance for the design and construction of subsurface drainage facilities for airfields, roads, streets, parking lots and other paved areas. The criteria apply to paved areas such as airfields, roads, streets and parking lots having a relatively impervious surface such as asphalt concrete or Portland cement concrete. The criteria is limited to situations where the surface water can be drained by gravity flow and is mainly concerned with elimination of water which enters the pavement through the surface.
