ABSTRACT: Construction of high embankments in coastal areas containing soft soils is challenging. Such soils have high natural water content and are very problematic due to their low shear strength. The use of lightweight fill materials is a possible approach to build on soft soils as they impose lower loads resulting in lower settlements and reducing the possibilities of shear failure. Tire Derived Aggregates (TDA) is a cost-effective lightweight fill material that can be used in road construction. In this study, lightweight TDA fill materials is proposed for construction of road embankments on soft soils. The proposed construction is numerically simulated using the finite element software PLAXIS 2D to check its effectiveness. The results of the analysis indicate that the TDA can be very effectively used to reduce the settlement and stresses of the embankment. A full detailed extensive case study will be done to serve as a journal publication.
RÉSUMÉ: Construire une haute digue en milieu des sols meubles des zones maritimes est un défi affrontant les ingénieurs. La ers comme les agrégats dérivés de pneus (TDA), peut être une approche possible car ceux-ci imposent des charges plus faibles, ce qui entraîne une diminution des tassements et réduit les risques de rupture par cisaillement. Le TDA est une matière économique est simulée publiée dans une revue.
