Avalia？？o de recomenda？？es normativas sobre o uso de ensaios no controle de qualidade de fabrica？？o de geossintéticos

the use of polymeric materials known as geosynthetics in civil engineering applications has increased significantly in the last few years. in order to perform adequately, geosynthetics need to be manufactured according to rigorous quality control procedures. this paper addresses the frequency and the main types of laboratory tests used for quality control of geotextiles and geomembranes, which are the most largely used materials within the geosynthetic family. analyses based on technical standards from brazil, usa and europe show the need of quality control recommendations for a large number of applications of geotextiles and geomembranes in brazil. also, very limited information on this topic is available in brazilian literature. conversely, european standards on the subject take into consideration a very comprehensive number of types of geosynthetics and their applications in civil engineering, and represent today the most complete set of recommendations for manufacturing quality control of those products.
