Creep and Assessment of Geosynthetics for Soil Reinforcement

This seminar dealt specifically with the measurement of creep and how the results are applied in the assessment of soil reinforcements.

Aspects studied included design lifetimes of geosynthetics, and their safety margins.

Design load calculations vary from country to country so presentations from Europe and the US were included.

The papers covered: practicalities of measurement of creep and stress-rupture, the stepped isothermal method (SIM) for time-temperature superposition, derivation of design parameters and partial safety factors from laboratory data, the manufacturer's views on durability and certification, approval procedures for geosynthetics for soil reinforcement applications -UK practice, and creep and assessment practices for geosynthetics reinforcements in the USA.

An attendance list is also included. The event was endorsed by the International Geosynthetics Society.
