Abstract: The invention is a composite of interdependent engineering methods for earthen fill engineering and construction. The invention provides a computer method for correlation of the combination-specific energy values with all physical and engineering properties of all soil types and amended soil types in the compacted state that correspond to and are the product of the specific combination of field variables. In addition to interdependent utilization of the energy and corresponding engineering properties in method development, the energy and corresponding engineering properties are cross-tabulated or integrated with curve intercepts within data-based cross-matrices of all field combinations for use in engineering design, laboratory compaction testing, and construction controls including site-specific moisture-density curve location. The cross-matrix values are related or intercepted in a manner that permits determining values for additional field combinations that have not been tested on a full scale.

Abstract: The invention is a composite of interdependent engineering methods for earthen fill engineering and construction. The invention includes the development, utilization, and correlation of actual, cumulative field compaction energies, unique to and based on field combination-specific variables of any combination but including all of the following: soil type, compactor type, lift thickness, moisture content, and soil amendment type and mix.
