...M. Pinho-Lopes; A. M. Paula; M. L. Lopes ABSTRACT: Damage of geosynthetics during installation processes can affect their performance, so they are typically represented in design by applying reduction factors to their tensile strength measured in the laboratory. This paper contributes to better...

...S.Y. Lim; J.S. McCartney ABSTRACT: The reduction factors used to account for the impact of installation damage on the tensile strength of geogrids employed in mechanically stabilised earth (MSE) walls and reinforced embankments are usually obtained from field tests that simulate actual construction...

... Standards Institution (BS 8006). Table 1 summarises the results of various full-scale trials on the installation damage of geogrids subjected to compaction. From the results of these trials design guide-lines have been developed for the use of a reduction factor, F_ID, for deriving...

.... From simple tensile testing, the reduction factor for installation damage, RF_ID, was measured to be 1.42. Stepped isothermal method tests on the undamaged geosynthetic gave a creep-rupture characteristic with RF_CR = 1.70 for 106 hours (114 years). Thus...
