Vehicle Compaction Patterns in Clay Soil
ABSTRACT SOIL density patterns were deter-mined in a clay soil field at various moisture contents using different tire sizes with varying loads and repeated passes. Laboratory tests were performed on the field samples to determine plastic and liquid limits and compaction properties of the soil. The maximum change in dry density occurred between 12-26 cm under the center of the tires. Increases in dry density reached levels up to 0.35 g/cm3 after multiple passes of the tires.
