摘要

The main objective of this paper is to study the effect of adding shredded waste tires on shear strength, swelling, compressibility and permeability properties of clayey soils. For this purpose, three different types of clayey soils were selected from Irbid city in northern part of Jordan and brought to Jordan University of science and technology soil laboratory. The selection of three clay soils was based on their plasticity indices. The initial physical properties of these soils were determined such as, specific gravity, Atterberg's limits, maximum dry density and optimum moisture content, unconfined compressive strength, cohesion and angle of internal friction, swelling pressure and consolidation. The shredded tires passed US sieve number 4 were added to the soil at different percentages by dry weight of the soil. The percentages of shredded tires added to the soil were (2%, 4%, 6%, and 8%) by dry weight of soil for Atterberg's limits, swelling pressure, and consolidation and 8 different percentages for compaction test were added to the clayey soil namely ; (2%, 4%, 5%, 6%, 8%, 10%, 15%, 20%) by dry weight of soil. All samples were prepared at 95% relative compaction and optimum moisture content. The test results showed that increasing the amount of shredded waste tires will increase the shear strength and decrease plasticity index, maximum dry density, permeability, swelling pressure, swell potential, and the compression index of the clayey soil.
