• Description:
  Creep criteria for designing with geosynthetics as earth reinforcement were developed from in-air testing. It has been observed many times that geosynthetically reinforced soils (GRS) do not exhibit creep behavior predicted by the in-air tests. In fact, significant long-term geosynthetic creep in GRS features built with granular soils is unreported. This paper describes development of a testing device and testing protocol to measure performance of GRS composite behavior. Testing included geosynthetically-reinforced granular and cohesive soils as well as unreinforced soils. Loads and reinforcements were varied. Of the several conclusions, one of the more important is that geosynthetic creep will not occur in GRS composites with granular soils. In fact, loads in geosynthetics can become less with time in "typical" field constructions with granular soil.
