Abstract
Creep is a time-dependent deformation of soil under constant effective stresses. For investigation on the creep of
rock fill materials, 3 samples from 3 dams of Iran that are already under construction were selected. Normal
effective stresses were applied on the specimens with a large-scale odometer apparatus that is specially designed
for the research. Comparison of creep rate, amount of particle breakage and results of Los Angeles test shows a
relationship between these three parameters. Consequently Los Angeles test that is a simple and accessible test,
can give a prediction and estimation of behavior and properties of rock fill materials. Based on the test results, an
approximate relationship could be found between creep, particle breakage and Los Angeles test results.
