In recent years, awareness has grown of the need for subsurface drainage systems that can drain water from the pavement structural system. Much of the emphasis associated with studies of this subject has been on the removal of the moisture that infiltrates through the surface of the pavement, but it has also been recognized that the control of groundwater is an essential part of any effective highway subsurface drainage system. In this paper, rational analytical methods for the design of subsurface drainage systems for the control of groundwater are developed and presented. Although these methods are, in general, approximate in nature, they are soundly based on fundamental seepage theory. The resulting solutions have been used to prepare graphical design aids that can be readily applied by the highway designer. The use of these design aids is illustrated by a series of examples, and the results are compared with more-exact flow-net solutions obtained by the use of electric analogs. On the basis of this comparison, it concluded that the proposed design procedures, although approximate, do permit the development of good practical designs for subsurface drainage systems for the removal and/or control of groundwater in highway applications.
