Lateritic soils are widely spread in the Brazilian territory and they have been used as subgrade of pavement layers. Specifically, the Red-yellow latosols are usually clayey soils and are characterized as low bearing capacity materials for flexible pavement layers. As a conventional solution, soil stabilization with hydrated lime or Portland cement has ...
View ArticleThis paper presents a system for performing down-hole seismic test together with the piezocone test in order to determine the shear wave velocity (Vs) and for calculating the maximum shear modulus (Go); a basic parameter for analyzing the dynamic soil behavior and a reference value of the soil stiffness. The sys...
View ArticleThis paper presents statistical correlations between the static Young modulus Es and the normalized SPT penetration resistance N60 (corresponding to 60% of the theoretical energy of the SPT test) for preliminary estimation of settlements in sedimentary sands. The cor...
View ArticleCorrelations between CPT and SPT in sands are presented in this paper for different sand densities. Such proposition is based on the experience obtained with the use of piezocone whose penetration in sands occurs commonly
under drained condition. The SPT penetration, on the other hand, is much faster, occurring under a partially drained cond...
