Three-dimensional geocells (three-dimensional geogrid) that has high strength and stiffness, such that the geocell has a storage modulus of 500 MPa or greater at 23°C.; a storage modulus of 150 MPa or greater at 63°C. when measured in the machine direction using Dynamic Mechanical Analysis (DMA) at a frequency of 1 Hz; a tensile stress at 12% strain of 14.5 MPa or greater at 23°C.; a coefficient of thermal expansion of 120×10/°C. or less at 25°C.; and/or a long term design stress of 2.6 MPa or greater. The geocell is suitable for load support applications, especially for reinforcing base courses and/or subbases of roads, pavement, storage areas, and railways. |
