In Mechanistic design, the elastic properties of the constituent material is very fundamental for a save and durable pavement, in this study one of the constituent materials of road pavement (laterite) used as a subbase material was modified using lime. 0%, 2%, 4%, 6% and 8% lime were mixed with the laterite and compacted at energy level of standard proctor of 100mm diameter by 80mm long split cylindrical mould, a total of 60 specimens were prepared in all and an average of 3 specimen was used for the test. The compacted specimens were moist cured and tested after 7,14,21, and 28 days. The CBR machine was used with an adaptation constructed by the researcher to load the specimen to failure through static load application, the point load indirect testing technique was used to obtain syresses and strains for the lime lateritic soil mixture, the spss programme was used to predict the Elastic Modulus from compressive Modulus, the result show that the predicted values were close to the measured values with an average R2 value of 90% and that the Elastic and Compressive modulus increases with an increase in lime content up to 8% lime content
