Quality of compacted fills is essential to the proper functioning of a structure as a whole. Currently, quality control is achieved by testing to determine the deviation of moisture content of recently compacted soil in relation to optimum moisture and degree of compaction reached. Based on the results, deformability, permeability and strength related c...
View ArticleGeosynthetic geofoam has a cellular structure made of expanded polystyrene (EPS) and has been used as a lightweight material for geotechnical use in embankments, bridges seat, base and sub-base of roads pavements and infrastructure protection applications. This paper presents research data on EPS laboratory tests aiming to characterize Brazilian EPS for...
View ArticleThe characteristics of the subgrade soil, obtained from laboratory and in situ tests, are of fundamental importance to the design of pavements. The tests carried out in the field, such as CBR in situ, Bredboard and others, represent more significantly the conditions of the soil. The Dynamic Cone Penetrometer (DC...
View ArticleSome difficulties of performing an engineering geological mapping task in sites where residual and transported sandy soils are widespread are discussed in this paper. The study area is located in the municipality of Analândia in the southeast of Brazil. In this region landscape evolution is dominated by scarp retreat and relief inversion proce...
