The report describes the findings of the research project on subsurface drainage. The need for drainage was quantified by evaluating HVS tests on wet pavements. Geotextiles were investigated and various tests performed. Soil/geotextile compatibility and long term behavior were evaluated. Laboratory tests for geotextile selection are recommended and tentative criteria given. The use of fin drains was evaluated in the laboratory and a field study to monitor the efficacy of drainage systems was started
