This document is the BX 1500GGS Biaxial Grid. Product properties, structural integrity and durability values listed.

The specifications for the BX 1500GGS Biaxial Geogrid product type are Integrally Formed Biaxial Geogrid, Polymer: Polypropylene, Load Transfer Mechanism: Positive Mechanical Interlock, Primary Applications: Base Reinforcement and Subgrade Improvement.

The index properties chart lists values for aperture dimensions, rib thickness, tensile strength @ 2% Strain, tensile strength @ 5% Strain and ultimate tensile strength.

The structural integrity chart lists junction efficiency, flexural stiffness and aperture stability values.

The durability chart lists values for resistance to installation damage, resistance to long term degradation and resistance to UV degradation.

Load capacity values for maximum allowable strength for 120 year design is listed.

Dimensions and delivery clarifies that the biaxial geogrid shall be delivered to the jobsite in roll form with each roll individually identified and nominally measuring 13.1’ in width and 50.0 meters (164 feet) in length and 12.9’ in width and 3.9 meters (12.9 feet) and 164’ (50.0) in length.

Notes state that unless indicated otherwise, values shown are minimum average roll values determined in accordance with ASTM D4759-02.

Brief descriptions of test procedures are given for Nominal dimensions determined in accordance with ASTM D6637-10 Method A. Load transfer capability determined in accordance with ASTM D7737-11. Resistance to bending force determined in accordance with ASTM D7748/D7748M-14. Resistance to in-plane rotational movement in accordance with ASTM D7864/D7864M-15. Resistance to loss of load capacity or structural integrity when subjected to mechanical installation stress in clayey sand (SC), well graded sand (SW), and crushed stone classified as poorly graded gravel (GP). The geogrid shall be sampled in accordance with ASTM D5818 and load capacity shall be determined in accordance with ASTM D6637. Resistance to loss of load capacity or structural integrity when subjected to chemically aggressive environments in accordance with EPA 9090 immersion testing. Resistance to loss of load capacity or structural integrity when subjected to 500 hours of ultraviolet light and aggressive weathering in accordance with ASTM D4355-05.
