Resumo (PT): Being the most common soils in the north of Portugal, residual soils from granite were object of a research program aimed to a better understanding of the following aspects: (i) heterogeneity of soil profiles and depth of weathering; (ii) particle size distribution and plasticity characteristics; (iii) bonded structuring and its influence on mechanical properties; (iv) compaction characteristics and classification; (v) at rest stress state; (vi) stress-deformation and shear strength parameters; (vii) sampling and laboratory testing techniques; (viii) correlations between in situ tests (including SPT, CPT, DP and plate loading tests) and laboratory test results (namely, triaxials). In this paper some of these results are presented and discussed.
