Abstract: Engineering properties of laterites obtained from four different pits in Ede were evaluated to determine their suitability for road construction. Samples from each pit sites were subjected to sieve analysis, atterberg limits, linear shrinkage, compaction and California bearing ratio adopting British Standard 1377 (1990) testing methods. The sieve analysis results showed that percentage passing No 200 sieve ranged between 12.4 and 33.6%. The liquid, plastic limit and plasticity index varied between 24.0 to 34.7%, 16.7 to 23.6% and 7.3 to 11.1% respectively. The linear shrinkage is of the order 4.0 to 7.0%. The maximum dry density ranged from 1.72g/cm3 to 2.12g/cm3 while optimum moisture content varied from 9.0 to 11.1%. California bearing ratio ranged between 35 to 85%. The soils were classified as A-2-4 and A-2-6 which implied that they are suitable for sub-grade, good fill and sub-base and base materials. This geotechnical data obtained will be useful for future road foundation design and construction in the study area.
