Mechanically Stabilized Embankments Constructed with Low Quality Backfill
The report presents the results of a three year evaluation of Mechanically Stabilized Embankment (MSE) constructed using low quality backfill (greater than 32% passing the no. 200 sieve). Four MSE walls were constructed in mid-1982 along Interstate 80 near Baxter, California utilizing the clayey silt and clayey sand embankment available within the project limits. Two walls were instrumented to monitor stresses in the reinforcement, both horizontal and vertical movement, and lateral pressure on the wall face. The bid price for the MSE alternative was 12% lower than Reinforced Earth walls and 15% lower than concrete crib walls. The lower cost is attributed to reduced excavation and on-site availability of backfill. Dummy bar-mats were buried in the backfill at various depths and pulled out a year later to determine pullout resistance values for various configurations. The walls have performed well.
