| Abstract |
Over the past fifteen years, numerous studies, investigations, and full -scale projects have demonstrated the multiple benefits associated with the use of lime treatment for the construction of hydraulic structures. For instance, treating the soil with lime allows the valorization of locally available soils, and the simplification of the typical design cross section while also resulting in improved mechanical properties, higher erosion resistance, reduced overall costs, and material transport. However, durability concerns still limit a widespread implementation of lime treatment for hydraulic structures. Being a relatively recent technology, there is limited documented feedback on its longterm performance and the effects of prolonged exposure to weathering, particularly concerning its specific functional requirements in hydraulic structures. It is essential to prove that lime treated hydraulic structures are not only efficient and sustainable but also long-term solutions. This paper compiles and presents previous experiences with the aim of sharing the knowledge acquired during the construction and monitoring of full -scale structures. Dikes built in France, Belgium, and the Netherlands using lime treated soils are described. Their construction details, properties measured shortly after their construction, and results from monitoring campaigns conducted several years later, are discussed leading to valuable conclusions. |
