Road construction projects are essential infrastructure facilities for any countries, and high amounts of the budget allocated every financial year by decision-maker. The construction of road required researches,good plan and design, and excellent builders to discover innovatively and cost-effective engineered products to satisfy the increasing request that would economize the construction as well as increasingdurability. Despite the economic factor, this study will present a comparative review on the suitability of using rigid and flexible pavements in road depending on traffic, climate, foundation, life cost, materials, maintainability and safety consideration. The reviewed studies show that the design of concrete pavement is based on flexural strength whereas in the asphalt pavement is based on load distributing characteristics of the component layers. The concrete pavement life is slightly longer than asphalt pavement. The initial cost of the flexible pavement less than the cost of rigid pavement but conversely, the cost of flexible pavement is more than the rigid pavement with the long run because of the incurring costs of maintenance. The rigid pavement has better ability and durability to hold a shape against traffic and difficult environmental conditions than flexible pavement. ER -
