Abstract (en)

[origin: WO0188529A1] A composite of interdependent engineering methods for earthen fill engineering and construction is described. The development, utilization, and correlation of actual, cumulative field compaction energies, unique to and based on field combination-specific variables in combination including at least all of the following: soil type, compactor type, and moisture content are included. Lift thickness and soil amendment type and mix can also be included. Interdependent development of the field combination-specific compaction energies include the following novel combination-specific steps: rolling resistance energy versus dry density field trials, generation and direct curvalinear utilization of parabolic rolling resistance energy curves with roller passes, determination of asymptotic energy-density aproach ranges, selection and application of percentage density sectors on moisture-density curves, and projection of percentage density sectors onto corresponding roller compaction energy curves for selection and use of design compaction energy levels. Field combination cross-matrices are used in engineering design.
