DETERMINATION OF ALLOWABLE DESIGN STRENGTH OF POLYESTER REINFORCING MATS . REINFORCED EMBANKMENTS. THEORY AND PRACTICE. PROCEEDINGS OF THE CONFERENCE REINFORCED EMBANKMENTS, THEORY AND PRACTICE IN THE BRITISH ISLES, ORGANISED BY MMG CIVIL ENGINEERING SYSTEMS, HELD AT CAMBRIDGE UNIVERSITY, SEPTEMBER 27 1989

This paper describes the method to establish the allowable design strength of a reinforcing fabric. The first step in the calculation method is to establish the characteristic strength of the material in relation to various life times. This characteristic strength depends on the ultimate tensile strength and the creep characteristics of the material. Tests and test-results are described which have been executed to establish the relationship. Test-results will be shown in the form of stress-rupture lines and isochronous curves. Relations will be given between 0.8 m wide, strip and yarn test-results both for creep and short term tests. Results for various test speeds and temperatures are also shown. To find the allowable design strength the characteristic strength must be divided by various reduction factors. Tests and test-results are shown which have been executed to find these factors: mechanical damage, chemical attack, biological and environmental attack. (Author/TRRL)
