Abstract

Traditional techniques such as burning leads to some highly durable non-degradable synthetic materials that cause unrepairable environmental damages by releasing heavy metals such as arsenic, chromium, lead, manganese, and nickel. Today, scrap tires are used as lightweight alternative materials in many applications such as Retaining wall backfilling. In the present study, several laboratory models were carried out to evaluate the stability of Retaining walls reinforced with Plate anchors. Then, the effect of adding different contents (10 and 20 wt. %) of Crumb Rubber to fill of a mechanically stabilized Retaining wall with Plate anchors were investigated including its effect on bearing capacity and wall horizontal displacements during static loading. To visualize the critical slip surface of the wall, Particle Image Velocimetry (PIV) technique was employed. The results showed that the circular anchor plates provide a higher bearing capacity and wall stability in comparison to square plates. Also, it was found that the backfill with 10 wt. % Crumb Rubber provides the wall with the maximum bearing capacity. In addition, increasing the weight percentage of Crumb Rubber to 20 wt. % resulted in a significant reduction in bearing capacity and horizontal displacement of the wall, which occurred due to a decrease in lateral pressure against the whole walls. Moreover, an increase in weight percent of Crumb Rubber results in a decrease in failure wedge formation and expansion of wall slip surface while the failure wedge is not formed in mix of sand-20 wt. % Crumb Rubber.
