Use of Lightweight Fill for Landslide Repair: Media Vía Stabilization Project, the Cuenca-Molleturo Roadway, Ecuador

This paper describes the construction of a 13 m-high tieback-supported retaining wall to repair the Media Vía slope failure on the Cuenca-Molleturo Roadway in Ecuador. Construction of the reinforced concrete wall supported with 30 m-long tiebacks had to be modified during construction due to a conceptual error in the original design. During wall construction to a height of approximately 7 m, distress fissures appeared on the lower wall panels. The authors, working for the general contractor, designed and obtained the approval for the installation of lightweight fill paired with steel beam reinforcement as replacement for the design included in the contract documents. The wall was successfully completed in 2003 and shows no signs of further distress. An effort to document wall behavior under seismic loading was considered since reference points were previously installed to document permanent displacements.
