Abstract |
Silt soil cannot satisfy the requirements of highway construction because of its low strength. Increasing the use of waste and recycled materials in earthwork projects has created the necessity a better understanding of the durability and strength performance of these materials against weathering conditions. The reinforcing soil using randomly distributed natural or plastic fibers has been used since ancient times. However, reinforcing of subgrade with discrete metallic fibers is still a relatively new technique in highways construction. In this paper the properties of poorly graded silty soil, waste aluminium wires and aluminium chops are studied and the effect on geotechnical properties of the soil is investigated by adding different amount industrial aluminium wastes into it. The percentages 0.1%, 0.5%, 1% & 2% by weight respectively. Thus, the effectiveness of using aluminium wires and aluminium chops in stabilizing weak soil was investigated in the laboratory. The soil samples in natural state and when mixed with varying percentages of aluminium wires and aluminium chops were used for the laboratory tests that included atterberg limits tests, grain size analysis, standard Proctor compaction tests, unconfined compression tests and California bearing ratio tests. |
