Which of the following statements describes why soil testing is conducted following compaction during construction?
  1. Verify that the proper moisture content required by the specifications was achieved during compaction
  2. Verify that the soil density required by specifications was achieved
  3. Develop a moisture density curve to identify optimum moisture
  4. All of the above
Explanation
Answer: D - Soil testing is conducted following compaction during construction to accomplish all of the listed reasons. Generally, compaction performance parameters, such as moisture content and soil density, are specified for construction projects. The Proctor or Modified Proctor Test is performed on soils to determine the maximum achievable density and to identify the effects of moisture on soil density.
