The purpose of this study is to investigate soils engineering properties and prepare soil map ofrnAdet town. Samples from ten test pits were used for this study. Both disturbed and undisturbedrnsamples were retrieved from the open test pits dug manually.rnLaboratory tests performed on disturbed soil samples included natural moisture content, specificrngravity, Atterberg limits, free swell as well as grain size analysis. Oedometer consolidation tests,rnswelling pressure test and unconfined pressure tests were also carried out by performing tests onrnundisturbed samples.rnReconnaissance survey and laboratory test results revealed that the soils in the town are mainlyrntwo types. The first one which covers the northern part of the town is black clay soil which has arncharacteristics of specific gravity ranging from 2.62 to 2.67, liquid limit of 77-86%, plasticityrnindex of 42-51% , clay fraction of 56-71%, free swell values of 67-100%, compression index ofrn0.266, recompression index of 0.047,preconsolidation pressure of 250kPa,coefficient ofrnpermeability ranging from 10-8 to 10-11 cm/sec and swelling pressure of 125kPa.rnThe second type that is found in most parts of the town is red soils which are classified as clayrnand inorganic silts according to Unified Soil Classification System. These red soils haverncharacteristics of specific gravity ranging from 2.70 to 2.85, liquid limit of 47-72%, plasticityrnindex of 14-39%, clay fraction of 21-90%, compression index of 0.19-0.299, recompression indexrnof 0.023- 0.029,pre consolidation pressure ranging from 150 to300 kPa, coefficient ofrnpermeability ranging from 10-8 to 10-10 cm/sec and free swell values of 27-67.5%.
