(l0 m) high embankment over a deposit of very soft sludge. The design used geosynthetics for reinforcement of the embankment and wick drains to accelerate the consolidation in the sludge. Stage construction was used to allow consolidation of the sludge. To verify the design assumptions, a test embankment was completed in 1993. The performance of the test embankment provided the information for the design of the full scale embankment. This project provided the opportunity to demonstrate the application of research findings from the test embankment to actual design and construction. The objective was to demonstrate how research findings can be used in design and construction. This report shows (1) how the results of the test embankment were used in the design of the full-scale embankment and prediction of the embankment performance, (2) how observation of the embankment performance can be used as construction control and (3) how the results can be used in future application of similar technology
