EFFECTS OF INSTALLATION-DAMAGE LEVEL ON TENSILE STRENGTH PROPERTIES OF HDPE GEOGRID

Abstract

Tensile strength properties of HDPE geogrid, which was damaged by compaction in sandwich with gravel, were investigated. Damage level was evaluated by surface roughness measured by a laser microscope, and deformation of tensile tests was evaluated by image analysis method. Effect of damage level on tensile strength properties is discussed statistically. Achievement of this paper will contribute for design strength evaluation of geogrid.
