EVALUATION OF DESIGN METHODS OF SUBSURFACE DRAINAGE FACILITIES FOR HIGHWAYS

The primary purposes of the study were to evaluate the methods used by the State Highway Department of Georgia for the design of highway subsurface drainage facilities, to compare these methods with what other States are doing, and to recommend, if applicable, research projects and/or additional studies which would lead to an improvement in these methods. The study consisted mainly of a library search and the analysis of two questionnaires on subsurfaces drainage which were sent to the fifty State Highway Departments plus District of Columbia and Puerto Rico. What Georgia is doing in connection with subsurface drainage is in keeping (for the most part) with what other States are doing. No two States have evolved to exactly the same place in their approach to solving the problem of subsurface drainage. In general, the highway departments have not kept abreast with many of the advances in problem solving techniques for flow through porous media. Recommendations were made which outlined research projects. Basically these amounted to better utilization of the aforementioned problem solving techniques and more effort expended in obtaining better data for design and verification of the design models. /FHWA/
