Handbook of Geosynthetic Engineering - ICE Virtual Library

An increase higher than 40% of the strength of the soilgeogrid interface when the relative density of the sand changes from 50 to 86% is due to the greater soil and soilgeogrid strength in the denser sand. The displacement of the geogrid decreases, increasing the interface stiffness modulus and the pull-out force.

For machines and structural applications, basic properties of materials are mechanical properties and fracture toughness. KMTL calibrates and controls testing machines to domestic and international standards (JIS, ASTM, ASME, NK, DIN, ISO and other international standards) and uses standardized test methods to assure accurate and traceable data.
