CHARACTERIZATION OF LATERITIC SOIL IN RUMUEME, PORT HARCOURT.
Abstract
ABSTRACT
This project investigates the geotechnical properties of lateritic soils from Rumueme, Port Harcourt, to assess their suitability for engineering works. Soil samples were collected from three points within a borrow pit and analyzed for natural moisture content, grain size distribution, and Atterberg limits. The natural moisture contents ranged from 8.93% to 17.51%, while grain size analysis showed less than 12% fines, classifying the soils as poorly graded sands (SP) under the Unified Soil Classification System. The liquid limits ranged from 25.47% to 29.87%, plastic limits from 13.95% to 16.54%, and plasticity indices from 9.66% to 13.33%, indicating low to medium plasticity. AASHTO classification placed Sample 2 in group A-2-4, suitable for road construction, while Samples 1 and 3 fell into A-2-6, requiring stabilization before use. The study emphasizes the variability of lateritic soils and the importance of site-specific characterization in geotechnical design.
