Soil-Processing and Compaction 11-1Chapter 11Soil- processing and CompactionHorizontal construction projects such as roads and airfields areconstructed using a variety of soil types. The suitability of these materialsfor construction applications depends on their gradation, physicalcharacteristics, and load-bearing capacity. While some soil types aresuitable for structural purposes in their natural state, others requireprocessing such as adjusting the moisture content by mixing and there is a direct relationship between increased density andincreased strength and bearing capacity, the engineering properties ofmost soils can be improved simply by Compaction . soil properties andcompaction requirements are discussed in FM PROCESSING11-1. The amount of water present in a soil mass affects the ease ofcompaction operations and the achievable soil density.
