Artigo completo:

The present study has the main objective of discussing about the characteristics and behavior of potentially expansive soils. These soils are present in several geographic regions across the world and exhibit variations in volume that consists of expansion or contraction, which are function of increasing or reducing its moisture content. A survey of the technical literature on the topic was carried out to support the study. The used methodology consisted of the application of direct and indirect methods that are based on index properties and in the conduct of laboratory tests. The obtained results were analyzed and compared to estimate the swelling potential and soil behavior. Therefore, the final considerations were presented.

O presente estudo tem como objetivo principal discutir sobre as características e comportamento de solos potencialmente expansivos. Esses solos estão presentes em diversas regiões geográficas do mundo e apresentam variações de volume que consistem em expansão ou contração, que são função de aumentar ou reduzir seu teor de umidade. Para subsidiar o estudo foi realizado um levantamento da literatura técnica sobre o tema. A metodologia utilizada consistiu na aplicação de métodos diretos e indiretos baseados em propriedades de índice e na realização de testes laboratoriais. Os resultados obtidos foram analisados e comparados para estimar o potencial de expansão e o comportamento do solo. Portanto, foram apresentadas as considerações finais.
