Lime Treated Materials for Embankment and Hardfill Dam
Sols traité à la chaux pour les remblais et les barrages durs
Résumé
This paper describes the SOTREDI project, “Soil TREatment for Dikes”, undertaken by Lhoist Group, a lime producer, since 2005. This project was led in partnership with research centres and universities, and presents some potential applications. The objective was to demonstrate that soil treatment with lime, besides enhancing the materials workability, confers high levels of mechanical properties, low permeability values, and is likely to reduce piping and internal erosion hazards, and to significantly increase the erosion resistance against overtopping and overflowing. This paper is a first step toward the application of lime-treated soils in earthen hydraulic structures (namely canals, dams, dikes and levees).
