The main purpose of this study is to examine the influence of drying-wetting cycles on the swelling of disturbed expansive soil at the micro-scale. Swelling curve – the relationship between swelling displacement and water-absorbing time – is measured based on specimens that experienced 0-4 drying-wetting cycles. Ass...
View ArticleLaboratory tests were conducted in soft clay deposits at the Macae/RJ airport in order to obtain geotechnical parameters for a new runway design. The quality of soil samples, extracted with both brass tube (thin-walled) and reinforced PVC tube (thick-walled) soil samplers, was assessed. Both samplers were 700 mm long, with a 7 degree chamfered cutting e...
View ArticleThis paper discusses the residual shear strength of a granulite residual soil that was involved in a large landslide in Brazil. The residual strength was investigated because of the great mobility achieved by the soil after failure. The experimental program comprised physical and mineralogical characterization and residual shear strength measurements. D...
