A method for bulk density determination of gravel rich or thin soil horizons A limitation of bulk density determinations using the core sample method is that soil horizons must be thick enough for coring and nearly free of rock material. The significance of the proposed method lies in the fact that it is applicable also to soil samples rich in rock fragments and/or thin horizons. The samples are impregnated in the laboratory using an epoxy resin. Bulk density (ρ b ) is determined after hardening according to the following equation:ρ f = density of soil material Bulk densities determined by the new method were found to agree well with such resulting from the core sample method.
