Geotechnical Investigation and Index Properties of Laterites

Abstract:

The usage of laterite is highly in the demand in all aspect of project. Assessing the index properties of lateritic soil from quarries in Kuje Area Council of FCT which can be used for construction needs. The characteristics of the laterite such as In-situ quality of laterite, color, Physical appearance, structure, and strength were examined by assessment. Quarried lateritic gravel from different quarry depths was enumerated for some index characteristics. Mechanical assessment of laterite from the location was performed to determine the amounts of the various characteristics, textures, and structures that were analysed by taking samples. The general characteristic including mechanical properties of laterite were however seen to be dependent on the soil in-situ profile characteristics, color, and general properties. The characteristics of laterite discovered to different totally concerning the area and depth of the quarry. There was an inquisition to understand the connection in between physical characteristics, and the general strength of the laterite. The results of the analyses are Atterberg Limit with Liquid limit 58% & 68% Plastic limits with 32% & 46% and plasticity index with 26% & 22%, other test are sieve analysis, with AASHTO A-7-5(5) & A-7-5(2) and Compaction test with O.M.C of 20.4% & 24.6%, M.D.D with 1.630 & 1.560, Soil specific gravity test with average 2.71 while permeability test has average 2.71 permeability. It is discovered that the samples needed to be stabilize so as to have strength to withstand imposed pressure or load after stabilization.
