Abstract

Soil improvement has long played an important role in civil sciences, especially in geotechnics. However, with the passage of time and the lack of resilient lands for the construction of more advanced construction structures, engineers in this field decided to use new methods to stabilize and reinforce problematic soils. Also in recent years, environmental problems such as the increase of waste and industrial waste and their release into the living environment have created problems for the life of living Creatures. In these circumstances, geotechnical engineers have tried to use these materials in construction projects to protect the environment and, also, due to the very low cost of waste materials, reduce the economic costs of soil improvement projects. As a result of this study, granular soil is reinforced in two loose and semi-dense states using Polymeric industrial waste material called full ethylene-vinyl acetate (EVA). The experiments were performed at different weight percentages of EVA (0, 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2, 2.25, 2.5, 3 and 4), without adding moisture and using the CBR device. The results show that soil CBR has increased significantly with the use of these additives, and its effect on the soil increases with the reduction of the specific weight of the soil.
