Which of the following statements is most true?

The assertion that any number of rollers can be used, as long as compaction is being obtained, reflects a practical understanding of the compaction process in asphalt paving. The effectiveness of compaction is not strictly determined by the quantity of rollers but rather by their type, the technique used, and the conditions under which they are employed.

In practice, the goal of achieving the correct density and compaction of the hot mix asphalt is paramount, and this can often be accomplished with varying equipment configurations. It's essential to focus on the work being performed, which includes the capacity of the rollers to achieve the desired mat density. Factors such as roller weight, type, temperature, and the asphalt mixture itself play critical roles in determining effectiveness, rather than adhering to a strict rule about the number of rollers.

Other statements imply specific conditions or limitations that may not universally apply. For example, asserting that three rollers are always necessary may be too rigid for different job site conditions. The suggestion that pneumatic rollers should be exclusively used for finishing is too narrow, as various types can be appropriate depending on the scenario. The statement regarding the use of fuel oil for cleaning drums is also not generally recommended due to environmental and safety concerns.

Therefore, the emphasis on the successful achievement of compaction
