Durability Testing of Geogrid in High pH Conditions for Sustainable Alternative MSE Backfill
This paper outlines a detailed multi-year investigation of the reduction in tensile strength for one particular coated polyester (PET) geogrid exposed to pH values ranging between 10 and 11.4. Arrhenius modeling was used to extrapolate the degradation rate of the geogrid tensile strength to 20°C over a 75–100-year design life and determine appropriate durability reduction factors for a pH range of 10–11.4. This durability reduction factor in elevated pH environments will allow for the calculation of long-term design strength (LTDS) for the geogrid reinforcement tested to be used in a greater range of pH environments, often encountered in the mechanically stabilized earth (MSE) industry.
