Soil compaction caused by high axle loads— review of concepts and experimental data

Abstract Current concepts, theoretical analysis and experimental data on soil compaction under high axle loads are critically reviewed and analyzed. Based on theoretical considerations and experimental data it is suggested that subsoil compaction is expected to occur under specific conditions (wet, homogeneous, and deep soil under high contact pressures). Measured changes in soil bulk density, physical properties, and crop yields (published in the literature), attributed to high axle load induced soil compaction, are not uniquely proven and can be attributed to other processes as well. Further research directed towards understanding and forecasting changes of soil properties under traffic loads is recommended.
