A section of I-670 contains an embankment over a deposit of soft sludge. The design used geotextiles for soil reinforcement and wick drains to accelerate the consolidation in the sludge. State construction was used to allow consolidation of the sludge. To verify the design assumptions, a test embankment was built in 1993 and the observed performance of the test embankment provided the necessary verification. The objective of this project was to demonstrate how the findings from the test embankment was used in design and construction. Predictions of consolidation rate, settlement, horizontal movement, geotextile strain and sludge strength were made using conventional and finite element methods and material properties determined from laboratory tests and performance of the test embankment. Overall, the prediction methods estimated the right order of magnetude of consolidation rate, settlement, horizontal movement, geotextile strain and sludge strength.
