Abstract:
1. A method for producing a ready-mix soil material, comprising the steps of: (a) crushing earth material excavated from a work site; (b) sieving the earth material after crushing so as to obtain raw soil material; and (c) mixing metered amounts of the raw soil material and at least one strength-enhancing additive in an automated manner so as to obtain the ready-mix soil material, wherein the method further includes, prior to step (c), analyzing samples of the raw soil material in terms of clay, sand, and gravel contents, with reference to results of analysis of the samples, preparing ready-mix soil material formulations having different mechanical properties by varying amounts of the raw soil material and said at least one strength-enhancing additive, and establishing a database for the ready-mix soil material formulations.
