Abstract

Three types of geogrid were installed with differently sized filling particles. Residual tensile strength decreased only slightly when small particles were used. Larger particles greater affected the PET filaments, sharply reducing residual tensile strength. Particle size distributions affected the grids' average installation damage factors, while irregularly distributed large particles determined the actual installation damage. Installation damage reduction factors were calculated through analysis of the filling materials' particles; the results were compared with those from lab index testing.
