Abstract—Soil is one of the most important and primary media for any construction work. The strength and durability of any structure depends on the strength properties of soil. Nowadays, scarcity of good land for construction which is one of important problems for engineers using land increases demand for unsuitable soils. When the mechanical qualities of unsuitable soils are lower than those required, reinforcing can be an option to improve performance, notably in enhancing its strength. Use of waste material is alternative method as low-cost material for soil reinforcing applications. In this study, two waste material were used together at different content. The waste material mixtures obtained from marble dust and scrap tire rubber were used for the stabilization of clayey soil. Unstabilized and stabilized clayey soil samples subjected unconfined compressive strength tests to investigate the waste material mixtures on the strength properties of clayey soils. As a result, it is concluded that the waste material mixtures obtained from marble dust and scrap tire rubber can be successfully used for the reinforce of clayey soils in the geotechnical applications.

I. INTRODUCTION
The soil is one of the most important and primary media for any construction work. The strength and durability of any structure depends on the strength properties of soil (Nath et al., 2017). Clayey soil (CS) is generally classified as expansive soils and these soils are known to cause severe damage to structures resting on them. However, these soils are very important in geology, construction, and for environmental applications, due to their wide usage as impermeable and containment barriers in landfill areas and other environmentally related applications (Erguler and Ulusay, 2003; Harvey and Murray, 1997; Kayabali, 1997; Keith and Murray 1994; Murray, 2000; Sabtan, 2005; Kalkan and Akbulut, 2004; Kalkan et al., 2019; Indiramma et al., 2020).
