Estudo de caso do projeto de restauração da rodovia MS 157: perímetro urbano de Itaporã-MS

Abstract

Paving is extremely important for locomotion of the population, in a country like Brazil that carries 68% of its cargo and 97% of its population by roads, it is urgent to improve the system, not only for those who carry out transportation activities, but also for all sectors of the economy and society in general. In this context, the present research had as objective to present a case study of the asphalt reconstruction project of the stretch MS 157 from the embankment to the pavement, showing its importance for the expected performance of the pavement. The results showed that the soil type in which the old pavement was built was in a critical state, with low resistance and unstable material due to the great presence of water in the subgrade. Finally, the flexible pavement was the model of pavement adopted for presenting lower cost compared to the rigid pavement, being also essential the drainage pipes and deep drain.
