Resumo(s)

Two geosynthetics were subjected to the effect of damage during installation (DDI) using real conditions, when installed in experimental works. The effects of the damage induced on the geosynthetics by these procedures were evaluated using wide-width tensile test. Simultaneously a test program was implement-ed to carry out pullout tests (according with EN 13738: 2004) to characterize the behaviour of the soil-geosynthetic interface. The geosynthetics tested include two different materials with different structures. The effects of DDI on the pullout behaviour of the geosynthetics is presented and discussed. The values of the re-duction factors determined from the results obtained are also presented. The main conclusions are stated.
