Geogrid reinforcement of soil has been successfully used for many years in a wide variety of applications. A huge development plan is expected in Iraq. The use of modern techniques like geogrid reinforced earth is expected. It is essential to gain experience in testing methods of geogrids using the available materials produced nationally, in neighboring countries and in developed countries. Some manufacturers do not provide sufficient data on the tensile properties of their products.
This paper presents data obtained from a series of laboratory tests performed on various configurations of geogrids. The tests are conducted to determine the physical properties of various seven types of geogrids, these types of geogrids were manufactured in Iraq, Iran, China and Britain. The mechanical properties included peak tensile strength, modulus of elasticity, upper yield strength, lower yield strength, tensile strength, non-proportional extension strength, total extension strength, fracture elongation, elongation at maximum load and total elongation as well as other physical properties such as aperture size, mass per unit area, rib thickness, rib width, junction thickness, roll width, mesh type, standard color and polymer type. The single rib strength test according to ASTM 6637-01 was performed using a computer controlled electronic universal testing machine. The results were compared with some information available from the manufacturers. Good agreement was found between the results obtained from the present tests and those given by manufacturers.
