ABSTRACT
In this study, the compaction and permeability characteristics of the borrowed pit laterite obtained from the Ekosodin Community, Benin-city have been basically evaluated. The analysis of these characteristics were necessitated by the need to ensure that the material meets the required strength value needed for construction and other engineering purposes. The study was slightly hindered by the uneasy accessibility of the borrowed pit material from the study area which was closely monitored by the community’s vigilante corps.
The laboratory tests were carried out in accordance with the specified British Standard Code (BS 1377).
Laboratory method was adopted and used for all the experimental test carried out on the representative soil samples. All the tests were carried out in accordance with the provision of the British code for the procedures of such tests.
The Atterberg’s test showed that the average Liquid Limit (L.L) of the soil is 31.83%, the average Plastic Limit (P.L) is 16.82% while the average plastic index (P.I) of the soil is 15.01%. The average Maximum Dry Density (MDD) of the soil is 1.72gc.
The average Optimum Moisture Content (O.M.C) of the soil was observed to be 13.1% while the average permeability coefficient of the soil is 6.532cm/s
