Twelve year creep tests on geosynthetic renforcements

Greenwood, J.H. / Kempton, G.T. / Watts, G.R.A. / Bush, D.I.

This paper reports the results of creep tests of up to 12 years' duration on six different reinforcing geotextiles. The measured creep strains are close to those which would have been predicted after 1 year, thus providing some assurance that the strain predicted for a design life of 120 years may be correct. Creep rupture data are provided for polyester strip and for polyethylene grid, with times to rupture of 3 years and tests at comparable loads lasting for 12 years. Partially factored design strengths (T_CR/f_m122) determined according to BS 8006 (1995) are presented.
