Abstract

High strength woven polyester geotextiles were tested for manufacturing quality control purposes, and for project approvals.This testing included both single end breaks, and full wide width strength testing. Wide strip tensile strengths were determined using ASTM D4595, “Tensile Properties of Geotextiles by the Wide Width Strip Method”.

Results show consistency in single end breaks, with significant variability when full wide strip tensile specimens were tested. Results were variable both in ultimate strength determinations and at 5 and 10% Several laboratories also tested this material, with their results presented. A summary of the results is discussed followed by recommendations for modification to ASTM D4595 to limit results variability.
