Geosynthetics - Test method for the determination of the strain hardening modulus of PE-HD geosynthetic barriers

Scope

This document specifies a test method for the measurement of the strain hardening modulus which is used as a measure for the resistance to slow crack growth of polyethylene. The strain hardening modulus is obtained from true stress versus draw ratio curves on PE-HD geosynthetic barrier samples.
This standard specifies how measurement is performed and how the strain hardening modulus is determined. Details of the required equipment, precision and sample preparations are given.
This test method is suitable for all PE-HD types of GBR-P.
