A Study on the Effects of Waste Rubber Tire Dimensions on Fine-Grained Soil Behavior

Mashhad city is located on alluvial deposits where the expanded area of this city, especially the central and eastern areas surrounding Imam Reza holy shrine, are built on weak and fine-grained deposits. Therefore, the soil improvement would be inevitable due to construction of high-rise buildings such as hotels and commercial complexes in these areas, as well as restructuring old buildings. Today, the use of waste rubber tire to stabilize the soil is not only efficient to secure human health and clean the environment but also as an inexpensive additive to improve the behavior of problematic soils. In this research, waste rubber tires in three different dimensions (
