Abstract
A series of tests on geosynthetic soil bags filled with recycled concrete aggregate was conducted to clarify the stress-strain behavior so that waste materials, such as crushed concrete can be economically exploited for construction works such as repairing small earth dams. The strength of the soil-bag system in compression was found to be quite high compared to the expected loading level, however large deformations observed during the tests hinted for the probable stability problems. The two approaches thought to reduce those initial settlements, vibratory compaction of soil bags during preparation and preloading aspect, were quite effective however, strain levels are still higher probably because of the weaker geosynthetic soil bags used in the present research.
