This study was carried out in order to determine cement, lime and bitumen prerequisite of some lateritic soil specimens as sub base materials. Soil specimens A, B, C was collected from Dual carriageway road construction project at Estate Iwo road, Osogbo, Osun state and stabilized with 0, 3, 6, 9, and 12% of cement, lime and bitumen. Various laboratory test was conducted on the soil specimen such as California Bearing Ratio (C.B.R), Compaction, Atterberg’s limit test and particle size distribution. The investigation revealed that beneficial effects were obtained by the addition of cement, Lime and Bitumen to improve the strength of weak or poor soils. The C.B.R values are 9.88%, 4.36% and 7.27% for sample A, B and C respectively at 0% additive content and at 12% additives, the samples gave C.B.R values of 55%, 50.0% and 50.00% by using cement. All the three samples have maximum C.B.R values of 45.0% with lime as additives. For using bitumen, result gave maximum C.B.R values of 41% for sample A and B and Sample C have 40.0%. Addition of additives improved the samples from a poor subbase material to an excellent subbase material with C.B.R values over 30%. Hence, soil improvement of laterite samples from the studied site can be carried out successfully by using Lime or bitumen judging from the result of the various tests on the different soil – additive mixtures.
