Where can you find in situ tests for subsurface investigations?

• A. Handbook
• B. MUTCD Documentation
• C. Federal Test Methods
• D. Construction Standards Manual

Answer: (A)

In situ tests for subsurface investigations are typically documented in a handbook, which serves as a comprehensive reference for various testing methods and procedures. Such handbooks encompass a wide range of geotechnical engineering applications, including the techniques and standards for performing in situ tests, such as standard penetration tests, cone penetration tests, and various other soil testing methods. These resources provide essential guidance on how to conduct testing in the field, interpret results, and apply them to engineering design and analysis.

While the other options provide valuable information related to engineering, design, and construction practices, they do not focus on the specific methodologies and standards for conducting in situ tests. For instance, MUTCD documentation primarily addresses traffic control devices and roadway safety. Federal Test Methods are generally associated with material testing rather than subsurface exploration. The Construction Standards Manual could offer construction guidelines but would not typically delve into specific testing methodologies unique to subsurface investigations. Thus, the handbook stands out as the most relevant source for in situ test procedures in subsurface investigations.
