Investigations on Index Properties and Maximum Dry Density of Soils Found in Kemise Town

Abstract

The objective of this research is investigations on some of the index properties and maimum dry density of soils found in Kemise town. To find the necessary information from the sub soil, geotechnical investigation on engineering properties of soil is very essential and it is one of the most important parts of Foundation engineering. However, the engineering properties of soils in the area are not studied. To achieve the central aim of this research nineteen disturbed and undisturbed soil samples were collected from eleven test pits. Thereafter, tests for engineering properties were carried out in the laboratory. The dry densities of the soil are ranges from 1.37 to 1.61 g/ , while the optimum moisture content ranges from 20 to 31%. So the dry density of cohesion less soil has relatively higher dry density than cohesive soil. According to engineering properties test results, it is concluded that the type of soils found in Kemise town is clay, silt and silty sand. The tentative soil map is prepared according to the USCS soil classification.
