Résumé / Abstract
Lhoist Group, a lime producer, since 2005. This project was led in partnership with research centres and universities, and presents new perspectives for the use of soils in hydraulic context. The objective was to demonstrate that soil treatment with lime, besides enhancing the materials workability, confers high levels of mechanical properties and low permeability values. Lime-treated soils also offer a reduction of piping and internal erosion hazards, and 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).
