Description of the stone-soil media used in the oak study by stone to soil mixing weight ratio, compactive effort, and dry density. Each number represents a mean of 7 replicates. Mean stone matrix density and weight percentage of the soil fraction are for comparison to the materials shown in Figures 1 and 3.
| Stone to soil mixing ratio | Mean compactive effort (kJ/m3) | % of standard AASHTO compactive effort | Mean replicate dry density by treatment (Mg/m3) | Mean stone fraction density (Mg/m3) | Weight % of soil fraction |
