Each year large quantities of tire wastes are released to the environment in an undesirable way. Those waste materials cause many environmental and economic problems. This study introduces an attempt to improve Gypseous soil properties using rubber tires waste. This paper presents an experimental study that explores the possibility of using rubber tires waste as an additive to improve the strength of gypseous soils. Different percentages of the waste material (2, 4, 6 and 8%) were mixed with the designated soil. The obtained results show that the angle of internal friction increases significantly with the addition of a different percentage of tire residues, unlike cohesion which was barely affected. In addition, the waste tires rubber minimizes the maximum dry density and optimum moisture content for this type of soil. The difference in optimum moisture content and maximum dry weight with the addition of waste fraction is linear.
