Summary:
This study concerns the improvement of soils in the Basrah area. Two types of soil have been selected, the first from the Garmatt Ali place and the second type from the Abu Al-Khasseeb place. Natural (palm) fibers are used in the stabilization of these soils. These fibers were added by different percentages (0, 1, 2, and 3%) by weight of dry soil to improve soil properties. The selected soil is subjected to different tests, such as liquid and plastic limit, specific gravity, unconfined compressive strength, and compaction test. It was found that the addition of fibers to the soil affects compaction characteristics by decreasing maximum dry density and increasing optimum moisture content for both types of soils. The unconfined compressive strength increased with more addition of fibers. The effect of fiber content on swelling, the swelling percent reduced, especially during the first days of the test.
