Description of the clay loam test treatments used in the oak study by compactive effort and resulting density. Results are from 10 observations per treatment. Standard AASHTO optimum moisture content of the clay loam was found to be 18%, and a peak density of 1.674 Mg/m3 was observed (ASTM D 698 method A used in testing).
