Abstract
In this experimental work, we investigated the effect of salty water of Urmieh Lake on the proctor compaction tests on the rather well graded gravel-sand-clay mixture (GSCW) soil samples in the Soil Mechanics Lab of Azarbaijan University near by the Urmieh Lake. The clay content varied from about 1/6 to 1/3 of total weight of the test samples. The clay was obtained from area nearby the lake with about 5-10% bentonite which had high water absorption capacity. The proctor test results on these soil samples indicated that using the Urmieh lake water has reduced the optimum moisture content of the soil samples by about 16-27% compared to the samples tested using tap water in the Lab. The results also showed that the maximum unit weight of the soil samples has slightly changed using the Urmieh lake's salty water. Plasticity index of the soil samples has reduced from 25.6% to about 3.66% using the salty water of the Urmieh Lake. CBR value has also varied for the tested samples from 62.24% to 68.96%
