Twelve papers provide the tools necessary to understand the problems and techniques in testing and reporting data for strong reinforcement products and point the way toward repeatable and reproducible test methodology for those strong products.
Experiences with and improvements to ASTM D 4595 Standard Test Method for Tensile Properties of Geotextiles by the Wide-Width Strip Method and its counterpart ISO 10319 are at the heart of this publication, including discussion of solutions to gripping problems, sample size, definitions, and LVDTs.
Based on the findings in STP 1379 and continued research and evaluation, Committee D-35 on Geosynthetics expects to resolve associated problems and improve testing and reporting that is based on D 4595 and ISO 10319.
Audience: A valuable tool for design engineers, engineers of record, contractors, product manufacturers, testing laboratories, federal, state and local authorities.
