Question

which type of compaction equipment can be used for variations of 90% sand and up to 100% clay?

Sheepsfoot rollers are effective for compacting cohesive soils like clay and can also handle some sandy - clay mixtures. High - speed tamping foot is more for granular soils. Vibratory smooth drum is better for granular materials. Pneumatic - 50 ton is not the most appropriate for these soil types.
