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. Interdependent development of the field combination-specific compaction energies includes the following combination-specific steps: novel rolling resistance energy versus dry density field trials, novel generation and direct curvalinear utilization of parabolic rolling resistance energy curves with roller passes, novel determination of asymptotic energy-density approach ranges, novel selection and application of percentage density sectors on novel moisture-density curves, and novel projection of said percentage density sectors onto corresponding roller compaction energy curves for selection and use of design compaction energy levels. Interdependent correlation of the combination-specific energy values is made with all physical and engineering properties of all soil types and amended soil types in the compacted state that corresponds to and is 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 tabulated within cross-matrices of all field combinations for use in engineering design, laboratory compaction testing, and construction controls. The cross-matrix values are related in a manner that permits determining values for additional field combinations that have not been tested on a full scale.
