  • This paper deals with geotechnic characteristics of groups of soils developed from different lithologies in Castilla y León regían (Spain). Data come from a data base previously generated from 22 geotechnic studies of roads. The analyzed groups of soils are: a/luvia/ sediments from little streams which erode granitoids, gneisses and migmatites; alluvial sediments from medium-large rivers (sediments not conditioned by underliying rocks); eluvial soils coming from the weathering of granitoids, gneisses and migmatites; detrital sediments from Tierra de Campos facies; alluvial sediments from little streams in Tierra de Campos facies; eolic sands from Tierra de Pinares facies and miocene marls of Duero basin. The analyses revea/ good quality of eluvial soils comming from granitoids, gneisses and migmatites as frame material far road explanades and terraplains, a relatively low plasticity of the detrital sediments of Tierra de Campos facies and a correlation between density and C.B.R. index within differents soils groups. The /atter fact allows to obtain indicative C.B.R. index values far future road projects.
