Objective: Soil is often weak in sustaining heavier loads. In this study, investigations are made to determine the use of C&D (Construction & Demolition) waste materials in geotechnical applications such as formation and strength improvement of rural roads, and to evaluate the effects of powdered waste bricks & prolonged stored cement in the formation of rural roads. Analysis: The results obtained are made towards the effectiveness and usability of reinforcement as a replacement for pavement works used in rural road execution works as a cost effective approach. Findings: By addition of C&D waste materials in the sub-base layer of the road structure, the conventional laterite layer of rural road formation is further strengthened, quantity of utilization of laterite is reduced and thus leads to cost reduction in road laying. Applications/ Improvements: Due to the improvement of the strength in the sub-base layer subsequently the water bound macadam layer which is laid on the top of laterite layer will be stabilized further, thus increasing the life of the rural roads to a certain extent.
