| dc.description.abstract | Currently there is a belief within the geotechnical Engineering Profession that there is not strong form of correlation between plastic index with linear, volumetric shrinkages properties for a soil [16]. This project would concentrate on soils from one particular road project which is known as tendaho access road. The soils in tendaho have been predominately consist of clays, silts, sands and gravels. The analysis to determine if there is a relationship between plastic index with volumetric shrinkage, plastic index with linear shrinkage results was undertaken using a sampling and testing program for 29 soils that had different characteristics. The soils that were tested all originated from Pliocene-Pleistocene volcanic rocks and associated fluvio-lacustrinesediments. this formation and are located in in Afar depression 580 kms North-East of the capital Addis Ababa, within the lower delta of Awash basin. The soils that were tested ranged from silts with sands and extended through to moderatly reactive clays. All these samples were subjected to the same testing program and included atterberg limits, linear shrinkage, volumetric shrinkage, free swell and particle size distribution. Upon completion of the testing program the volumetric and linear shrinkage results were plotted against the plastic index. This data was then graphed and the strongest trendline was fitted to it and the corresponding equation calculated. For a correlation to be considered a useful estimating tool the strength of this relationship must exceed R2 =0.80[14]. There were three correlations which met the requirement of R2 > 0.8.The equations for these correlations could be used to estimate the plastic index from linear, volumetric shrinkage of a soil. | en_US |
