The objective of this research is the elaboration of a technical and economical analysis of the substitution of the existing parallelepiped pavement for rigid pavement (pavement concrete of Portland cement), with the purpose of intervention in the urban road characterized by heavy traffic, to improve the conditions of the bearing surface. Emphasizing the concept of analysis of the cost of maintenance, comfort and safety of these pavements for a period of 20 years. In order to develop this study, a data collection was performed, including traffic counting and analysis of pathological manifestations in the Padre Dionísio da Cunha Laudt Street in the city of Tubarão/SC. Some geotechnical tests were analyzed to obtain soil characteristics of the region for the final phase of the research, the dimensioning of the rigid pavement by the PCA/66 method and the budget were carried out. As a conclusion of this research, from the technical and economic analyzes carried out, the results indicated that the alternative of replacing the existing pavement for rigid pavement, proved to be advantageous in terms of cost and benefit. This type of pavement distributes more uniformly the requesting tensions, transmitting smaller deformations to the lower layers of the pavement. Rigid pavement is the best alternative for situations where traffic is excessively high, such as bus corridors, and highways with high-traffic of heavy vehicles. The high initial cost of implementation would be offset by the maintenance practically null in the period of 20 years and by the comfort and safety generated to the users.
