To understand the answer to this question, we need to understand the concept of compaction and the role of compaction equipment in achieving adequate workability.


Compaction is the process of increasing the density of a soil or aggregate material by reducing the air voids within it. The level of compaction achieved directly affects the strength and stability of the material. Workability refers to the ease with which a material can be compacted.


There are various types of compacting equipment available, such as vibratory plate compactors, sheepsfoot rollers, smooth drum rollers, pneumatic rollers, etc. Each type of equipment has different compaction capabilities and workability requirements.


In the given question, the phrase "adequate workability" refers to the level of workability required to achieve proper compaction. The compaction equipment available is not specified, but we can assume it to be typical compacting equipment like vibratory plate compactors or smooth drum rollers.

Among the given options, "Full" is the correct answer. This means that the compaction equipment available is capable of achieving the highest level of workability necessary for proper compaction. The equipment has the capacity to compact the material to its maximum density by reducing the air voids to the fullest extent.

The other options, "Half," "Quarter," and "Double," indicate lower or higher levels of workability, which may not be suitable for achieving the desired compaction. Half or quarter workability would result in insufficient compaction, leading to lower material density and reduced strength. Double workability would require equipment with higher compaction capabilities than what is available, resulting in over-compaction and potential damage to the material.

Therefore, the correct answer is option C, "Full," as it represents the adequate workability necessary for proper compaction with the compacting equipment available.
