A series of laboratory tests were undertaken to evaluate the effect of installation damage on the wide-width tensile strength of three Exxon Chemical woven polyester geotextiles. A variety of subgrade and backfill materials was used to simulate different field survivability levels. Tests were performed using a 1.2 meter by 1.2 meter installation damage box at Georgia Institute of Technology. An examination of unconfined creep testing of the highest strength woven polyester geotextile (10,000•:hours after initial tensile loading) is also included. The results of this study enable one to obtain design oriented factors of safety for these specific, high strength polyester woven geotextiles, and provides general information on geosynthetic installation damage assessment.
