Comparison of Pullout Behaviour of Polyester Geogrid and Polyester Strip Soil Reinforcement
This paper presents the results from laboratory tests on the pullout behaviour of polyester geogrid (GG) and polyester strips (PS) embedded in sands of different morphology and gradation. Pullout tests were carried out for three normal stresses of 20 kPa, 40 kPa, and 80 kPa in dense and loose conditions. The gradation and shear strength characteristics of sands confirmed to codal provision for reinforced soil structures (RSS). The test results showed that peak pullout resistance (PR) of GG is lower in dense conditions and occurs at higher strains than PS due to constrained dilatancy. Pullout resistance of under compacted sample shows significant reduction as compared to the dense sample. The interface apparent coefficient of friction was reduced 50%–60% in GG and 70%–75% in PS. The study reveals that proper compaction is an essential requirement for RSS built using either GG or PS.
