The topographic and geological conditions of several regions in Brazil favour the formation of large deposits of soft soils. Sometimes this requires the use of innovative techniques to allow constructions of geotechnical works in these sites. The presence of deep soft foundation soils has led to an increasing number of reinforced bridge abutments being ...
View ArticleThis paper describes the results of research carried out for evaluating the effects of hydrated lime, with and without chemical activators, for the modification (up to 2% lime) and stabilisation (more than 2% lime) of residual granite soils. The effects of the modification of granitic soils with the addition of 2% calcitic lime were studied; and the res...
View ArticleSoil water retention curve (SWRC) plays a fundamental role in characterizing hydraulic and mechanical behavior of soils and porous material in general. However, the determination of the SWRC is usually time-consuming. The objective of this paper is to describe a procedure for the determination of the SWRC using a high capacity tensiometer (HCT). The pro...
View ArticleAlthough expansive soils have been widely studied by different authors, just a few have made methodological proposals to comprehensively evaluate this phenomenon. The aim of this paper is to suggest a methodology which will serve as guideline to evaluate soil expansiveness in a... View Article
