USO DE SOLO-CIMENTO EM SOLOS ARGILOSOS PARA PAVIMENTAÇÃO

: Studying the stabilization of clayey soils is a challenge because it is a phenomenon responsible for settlement in foundations, as well as being a recent theme. The expansion of bentonite clays is a difficult control process whereas any change in humidity or density can accelerate this happening. Paving works in specific regions such as the Amazon have difficulty to be performed due the predominant soil kind in their territory, and the large presence of rivers. The main characteristics of clay minerals are described in the article, as well as their interactions with cement and/or synthetic zeolite. We sought a practical case of soil-cement pavement from the Amazon region to compare the results with others authors and evaluate their use with high activity clays. Finally, it was concluded that despite of the different consistencies that clay soil have, its use is possible in roadbed constructions.
