Abstract
The paper summarizes the results of several pullout box test series carried out on polymeric straps made of polyester (PET) yarns encased in polyethylene (PE) sheaths with a rough, continuous surface. The PET strap ultimate tensile strengths ranged from 30 to 100 kN/strap. Reinforcement specimens were subjected to pullout forces under different confining pressures using a large steel pullout box. Different reinforcement lengths and installation procedures were used. The test results were interpreted quantitatively with focus on damage to the sheath and yarn elements after pullout due to different installation/construction procedures. The consequences of damage during installation and pullout with respect to the long-term performance of strap reinforcement are explored. Implications to design and construction practice for PET strap reinforced soil walls are identified.
