Aplicação de geotêxteis na drenagem de pavimentos: análise de critérios de retenção, permeabilidade e sobrevivência

Abstract

Drainage is one of the most relevant factors to ensure the durability and safety of highways, as the presence of water within pavement layers can compromise structural integrity, reduce service life, and increase maintenance costs. In this context, the use of materials such as geotextiles emerges as a promising option to enhance the performance and cost-effectiveness of road construction. This study aims to specify the most suitable geotextile according to the criteria of retention, permeability, and survivability, applied to a highway project in the Midwest region. For this purpose, the criteria stablished by VERTEMATTI (2015) were adopted. The results showed that the GTX A geotextile satisfactorily meets all the established criteria, fulfilling the function of a filtering material. Therefore, this study demonstrates that geotextiles can be considered an effective alternative for pavement drainage.
