Which of the following does NOT require sampling and testing, provided it meets certain compaction criteria?

In the context of roadway construction and maintenance, sampling and testing of materials is a critical part of ensuring quality and compliance with specifications. However, certain conditions allow for reduced testing requirements.

Pavement widening less than 4.0 feet can be treated differently under specific circumstances, particularly when it meets defined compaction criteria. If the widening adheres to proper compaction standards, it may not need the same level of sampling and testing as more substantial pavement projects. This is often due to the idea that smaller areas pose a lower risk of significant defects, assuming they are constructed under the same standards as the adjacent pavement.

On the other hand, full-width travel lane pavements, ramps, loops, and temporary pavements generally undergo more rigorous testing protocols due to their essential roles in traffic safety and performance. Such areas typically involve more complex structural concerns and higher traffic loads, necessitating comprehensive quality assurance measures to ensure durability and safety over time.
