Description:
<jats:p>Geo-composites are generally made by hybridizing of some components among
geo-textile, geo-grid, geo-membrane, geo-net, and other materials. Due to practical applicability of
geotechnical structures, the demand of geo-composites, especially for drainage application, has
gradually increased. In the present study, the geo-composites bonded with geo-grid in chemical
process were investigated experimentally in terms of strain evaluation and creep response values.
Geo-grid plays an important role as a reinforcing material. Three kinds of geo-grid were prepared as
strong yarn polyester and they were woven type, non-woven type, and wrap knitted type. The sample
geo-grids were then coated with PVC. The rib tensile strength tests were conducted to evaluate
geo-grid products in terms of tensile strength with regard to single rib. The test was performed
according to GRI-GGI. The test results revealed that the tensile strains at the maximum tensile
strength showed very good tensile deformation characteristics in the range of 10.0-13.0% in terms of
mono-rib performance. Any significant trends have not found between warp knitted and woven type
geo-grid in terms of the tensile strength ratios. Further experimental analysis has been conducted to
investigate the wide-width strip tensile strength, contact point strength and creep features of the
geo-grid samples used in this study. It was concluded again from the experiments that the tensile and
creep strains of the geo-grid showed so stable values that the geo-grid prepared in this study could
protect geo-textile partially in practical structure.</jats:p>
