With rapidly developing infrastructures, road transport being one of them, engineers around the world have been looking for cost effective solutions to build roads. Pavement choice is an eminent part of any road construction process. But the pavement’s life cycle cost depends on different variables and one of the most important is the location. Numerous studies were conducted in different countries around the world including India suggesting rigid pavement is more economical in the long run than flexible. But, since the thickness of pavement very much depends on soil subgrade and traffic characteristics, more research based on highways need to be conducted. Significant cost and time can be saved if the right pavement for the right condition can be chosen based on supporting data and studies. Since rigid pavement is gathering curiosity in  Nepal regarding its comparison to flexible pavements, we can reach some conclusions based on other research and their findings through this  review paper.
