Determinação do volume de aterro para revestimento em estrada vicinal: uma aplicação do método da SD-LTAP

Abstract

According to the National Transportation Confederation (CNT), 87.8% of the Brazilian road network consists of unpaved roads, so-called dirt roads or roads. The constitution of these roads is due to the Brazilian economy being supported in the production and commercialization of primary products. And these roads serve as support and immediate infrastructure for the outflow of production. A large percentage of the secondary roads can be found in the rural environment, enabling socioeconomic development to be provided by providing accessibility to certain communities, allowing rural inhabitants access to basic services such as health, education, supplies and leisure. Considering the importance of these structures as well as the deficiency of the methodological and technological aspects for the development of more efficient suburban highways, the present work presents the application of a methodology of sizing the primary road surface, this methodology considers the climatic conditions, the mechanical characteristics of the soil as well as the traffic conditions of the region, making it possible to determine the volume of material needed to implement the landfill of the highway, together with the costs involved in this project.
