Evaluation of Interface Shear Strength Coefficient of Alternative Geogrid Made from Para Rubber Sheet.

In this work, elastic natural rubber compound sheet (RCS) and ribbed smoked sheet grade 3 (RSS) were studied as alternative replacements for polymer geogrid for soil reinforcement. In order to investigate the reinforcing effectiveness in three distinct environments using the interface shear strength coefficient () by the large-scale direct shear test, the RSS and RCS geogrids were installed independently in sand, lateritic soil, and clay. Using either an RSS geogrid or RCS geogrid, the average is progressively smaller in reinforced sand, lateritic soil, and clay, respectively.
