Résumé

Geotextiles are used in the constitution of landfill lining systems in order to protect the geomembrane against puncturing effects during installation of the granular drainage layer, then during the life of the landfill site, in relation with the weight of waste. The objective of this paper is to evaluate the performance of nonwoven needlepunched geotextiles having an average mass per unit area equal to 1000 g/m2 in protecting geomembrane, based on static puncture tests performed in 1m diameter cells. Recommendations are given in the following as regards the length of fibers, the elasticity modulus, the mass per unit area and the thickness of the geotextile depending on the nature of the granular material used.
