Interaction with soil strengthening is a critical problem in the construction of reinforced soil structures. It is therefore, important to examine the pullout mechanism and determine the relationship between soil and reinforcement. Most of the pullout experiments that have been performed in geotextile to date. This research was conducted to evaluate the pullout resistance of plain and deformed steel bar embedded in a mixture of tire shred sand and sand alone. Large-scale test model was designed and fabricated. Large-scale test model measurements were 1.2 m × 0.9 m × 1.5 m. Moreover, the research system was made of steel; it researched the impact of tire shreds and the diameter of deformed bars. It was inferred from the results, that pullout resistance enhanced with the introduction of tire shreds (2.267 KN/m) in the sand only (1.682 KN/m), and pullout resistance increased with an increase in normal load (1.7 to 2.0 KN/m). With deformed bars (1.032 KN/m), the pullout resistance of deformed bars was greater than for plain bars (0.868 KN/m).

土体加固的相互作用是加筋土结构施工中的一个关键问题。因此，重要的是检查拔出机制并确定土壤和钢筋之间的关系。迄今为止在土工织物中进行的大多数拉拔实验。进行这项研究是为了评估嵌入轮胎碎砂和单独砂的混合物中的普通和变形钢筋的抗拔性。设计并制作了大型试验模型。大型测试模型测量值为 1.2 m × 0.9 m × 1.5 m。此外，研究系统是由钢制成的。它研究了轮胎碎片的影响和变形钢筋的直径。从结果推断，仅在沙子中（1.682 KN/m）引入轮胎碎片（2.267 KN/m），拉拔阻力增强，拉拔阻力随着正常载荷的增加（1.7～2.0 KN/m）而增加。对于变形钢筋 (1.032 KN/m)，变形钢筋的拉拔阻力大于普通钢筋 (0.868 KN/m)。
