Which technique is most likely to improve soil compaction for construction activities?

The technique that most effectively improves soil compaction for construction activities is sheepsfoot rolling. This method uses a roller equipped with cylindrical feet that penetrate the soil and compress it as the roller moves over the surface. The design allows for deep penetration and effective compaction of various soil types, which is crucial for creating a stable foundation for construction. The sheepsfoot roller is particularly beneficial in compacting cohesive soils, such as clay, where achieving adequate density is essential to prevent future settlement issues.

In contrast, track walking involves machinery moving across the soil to compact it, but it is generally less effective than specialized equipment like sheepsfoot rollers. Bedding refers to the placement of material under pipes or structures, while stair stepping is a technique used for shaping slopes rather than directly improving compaction. Therefore, sheepsfoot rolling is the most targeted and effective method for enhancing soil density and stability in construction contexts.
