Soil compaction is a critical part of most engineered structures that use the earth or soil as a foundation or a base for support. The soil’s engineering properties, including strength, compressibility, and permeability, can be improved and become more predictable with the proper degree of compaction. The soil may also be a major structural component, as in the case of earth fill dams, levees or dikes, high road fills, and other embankments.
Unique to Manual 70 is the combination of established soil mechanics engineering fundamentals and the discussions on using the latest ASTM standards related to those fundamentals.
