THE USE OF GEOTEXTILES IN HIGHWAY WORKS

UTILIZACION DE GEOTEXTILES EN OBRAS DE CARRETERAS

An account is given of recent developments in geotextiles and their use. Originally developed for separation purposes in provisional works, geotextiles are increasingly used for permanent applications in strengthening, filtration and drainage. A geotextile is defined and the most commonly used materials listed. A comprehensive description is given of the characteristics required of a geotextile and tests described which are used to measure geometric hydraulic, mechanical and durability properties. The relative importance of these characteristics for the functions of filtration, drainage, separation and strengthening are discussed. Specific risks to durability are identified and include ultra violet (uv) radiation, heat, aggressive environments, creep and clogging. The use of geotextiles in roads is then examined in more detail. Two basic applications are identified -subgrades and formation levels and embankments and retaining structures. Principles are outlined which will govern the choice of geotextile type for each situation. This paper was originally published in Spanish in revista rutas, 1988, 4th quarter, 2(II), P30-49.
