La production des déchets de matières plastiques ne cesse de croître. On peut valoriser ces déchets en les réemployant pour renforcer les sols et améliorer leurs caractéristiques mécaniques. Pour obtenir la meilleure représentativité des phénomènes réels, les essais de laboratoire (frottement, ancrage, cisaillement) ont été effectués sur des appareils de grandes dimensions. Ils ont permis de mesurer l’influence de deux paramètres : la taille et la masse surfacique des éléments discontinus de renfort.
Abstract
The production of plastic materials waste increases continuously. It is possible to valorize these wastes by its reuse as soils reinforcement. On the other hand, this technique increases the mechanical characteristics of soils. A best representativity of real phenomena was obtained by laboratory tests (friction, anchorage, shear) carried out on big size apparatus. Tests carried out by this new shear apparatus permited us to observe the influence of two parameters : the size and the surfacic load of this reinforcement discontinuous elements.
