Abstract: This study identify the break-even-point between the use of a Rigid or Flexible pavement in function of the traffic and subgrade support related to cost/m2 and discount rate, through CBR method of Flexible pavement Design and PCA/66 Rigid pavement design. Consider intervention scenarios of 10 and 40 years with materials variations referred to the pavement structures of the same monetary and temporal landing through dependent variable Net Present Value (NPV). It shows that wherever design procedure used to define the pavement structure in a roadway enterprise, it is mandatory to follow with an economic analysis using the Life Cycle Cost Analysis (LCCA) concept. The conclusion shows to be mandatory to avoid options of pavement based only on its initial costs. The cost of a pavement involves initial cost and the interventions cost. The simple analysis of initial cost did not show to be the best option throughout the life cycle of a pavement under the point of view of the investor considering the money cost available in the market.
