Domaines nouveaux d'application des géotextiles
Résumé Les qualités particulières des géotextiles sur les plans mécanique et hydraulique conduisent à prévoir que l'emploi de ces matériaux se développera dans des applications nouvelles, à condition que les caractéristiques des géotextiles puissent être connues et mesurées de façon satisfaisante et que la durabilité soit assurée. L'article mentionne les ouvrages hydrauliques et maritimes; les étanchéités souples et le renforcement des ouvrages en terre; il s'étend un peu plus longuement sur l'emploi des géotextiles associé au bitume, comme interface antifissure sous une couche de roulement de chaussée et comme élément de continuité dans un enduit superficiel.
Summary Geotextiles have mechanical and hydraulic properties that make them particularly useful in civil engineering and soil structures. These properties are such that it may be considered as certain that new applications of geotextiles will develop in the future. However, if geotextiles are to be used as important elements in permanent structures, their characteristics will have to be known and measured precisely and according to testing procedures such that the obtained values are really significant for the project engineer. Also, the durability of geotextiles will have to be ascertained for a number of applications. The paper makes a review of the new fields of application of geotextiles that may be foreseen: hydraulic engineering, flexible impervious revetments, earthworks reinforced with geotextiles and pavements. Two pavement applications are particularly mentioned, where the geotextile is associated with bitumen: in the first one the geotextile-bitumen complex is used as an interface between two pavement layers for preventing the transmission of cracks; in the second the geotextile is used as a reinforcement for surface dressing. The present knowledge for these two applications shows that there are no technical problems for construction and that they are probably efficient; however they are too recent for economical justification to be established yet.
