A novel approach to specifying and creating rammed earth soil recipes, through a process of blending graded quarry material, has been presented. The soil recipes are highly consistent and reproducible, allowing the accurate control of parameters such as particle-size distribution. A novel technique for the consistent production of rammed earth cube samples has been presented that satisfies NZS 4298: 1998, and is in good agreement with the established Proctor standard for compaction. Under the proposed method for rammed earth sample production, the level of energy input used for compaction can be varied depending upon soil type. For a given compactive effort, the variation in dry density due to soil type did not appear to be directly related to the characteristic unconfined compressive strength of the rammed earth samples. Experimental data have been included.
