Estudo da viabilidade de aplicabilidade de diferentes métodos de dimensionamento de pavimentos asfálticos e intertravados em um condomínio horizontal na cidade de Santa Maria/RS

Abstract

A pavement is caracterizes by a set of layers of finite thicknesses, which are intended to resis the demands generated by vehicle traffic. Among the types of coating are the interlocking blocks, concrete blocks that When interlocked over a layer of sand, prevent their displacement and therefore resist the demands generated. Asphalt paviments are caracterized from a mixture of asphalt aggregates and binders, which, when correctly doses, grarantee the necessary resistance to absorb the efforts generated together with the other layers. both types of paviment have their specific design methods and the presente work aims to evaluate the applicability of diferente calculation methods for the design of a floor in a high standard closed horizontal condominium in the city of Santa Maria/RS, which has a low traffic. Still, the objetctive of this study is to make a financial comparison between all the design results obtained. In this project, the DNER and MeDiNa design methods were used for the design of aspahlt concrete and surface tratment and the PCA/84 and CMAA calculation method for the interlocking blocks. The study found that the use of the DNER method for the condition analyzed at work is not adequate, as it result in an oversizing. Still, the use of surface tratment doesn’t become a satisfactory option also due to it’s low applicability in the market. Therefore, the interlocked pavement presented itself the mos suitable for this situation, being algo de most economically viable option.
