SUMMARY OF WORKSHOP SESSION ON SUBDRAINAGE--ALBANY, NEW YORK

This paper summarizes the work session on subdrainage held at the 1973 Federal Highway Administration workshop on Water in Pavements in Albany, New York. It was generally agreed that the soil survey is the initial important effort in the identification of potential groundwater problems. While it was recognized that the soils engineers was the key person to make decisions regarding the level of groundwater problems and the most probable methods of solution in the early stages of design, it did not appear that many of the states were organized in a manner such that the soils engineer had much of an opportunity to follow the project through design and construction. A number of methods for controlling groundwater drainage were discussed: construction of deep surface ditches along the roadway, trench excavations, and slope protection blankets. The drainage of cut slopes is becoming rather routine, but each installation is a design job in itself. Few states were considering the installation of transverse drains--the drains installed beneath the pavement to pick up the longitudinal drainage--to any great degree. Many underdrain installations seem to be installed for the multiple purpose of draining the pavement and intercepting groundwater. Insulating pipes does not look favorable for use in large scale installations, but there is not a sufficient number of installations from which to draw a firm conclusion.
