Abstract:

A primary objective of the current study was to help ODOT expand its selection of approved

geogrid products for base reinforcement applications by producing measured data on selected

geogrids and a dense-graded base aggregate commonly used in ODOT roadway projects. The study involved in-isolation and in-aggregate laboratory testing of several base

reinforcement geogrid products from major geosynthetic suppliers. In-isolation tests included

rib strength and junction strength tests, and in-aggregate tests included a series of pullout

tests, large-scale cyclic plate load tests and field-scale installation damage tests Test results

on different geogrids in this study were used to quantify the significance of the geogrids in-isolation properties on their in-aggregate response under controlled conditions. These efforts

collectively will help ODOT and other state DOT engineers to revise their respective

specifications manuals for base reinforcement and subgrade stabilization applications
