2. COMPACTION EQUIPMENT The desired level of compaction is best achieved by matching the soil type with its proper compaction method. Other factors must be considered as well, such as compaction specs and job site conditions.

3. COMPACTION EQUIPMENT Cohesive soils clay is cohesive; its particles stick together. Therefore, a machine with a high impact force is required to ram the soil and force the air out, arranging the particles. A rammer is the best choice or a pad-foot vibratory roller if higher production is needed.

7. COMPACTION EQUIPMENT Granular soils since granular soils are not cohesive and the particles require a shaking or vibratory action to move them; vibratory plates (forward travel) are the best choice.

11. Field Compaction Equipment Rollers are used for field compaction and apply either a vibrating force or an impact force on the soil. The type of roller used for any particular job depends on the type of soil to be compacted. A smooth wheel or drum roller applies contact pressure of up to 55 lb/in2 over 100 percent of the soil area in contact with the wheel. This type of roller is generally used for finish rolling of sub-grade material and can be used for all types of soil material except rocky soils. https://www.youtube.com/watch?v=_TpTgrtH8H8 Smooth Wheel or Drum Roller

12. Field Compaction Equipment The rubber-tired roller is another type of contact roller, consisting of a heavily loaded wagon with rows of 3 to 6 tires placed close to each other. The pressure in the tires may be up to 100 lb/in2. They are used for both granular and cohesive materials. Rubber-Tired Roller https://www.youtube.com/watch?v=nOvpoZhz2l0

13. Field Compaction Equipment Tamping foot rollers They are used to obtain high contact pressures, ranging from 200 to 1200 lb/in2. The feet of the tamping foot rollers are specially hinged to obtain a kneading action while compacting the soil. tamping foot rollers compact from the bottom of the soil layer. https://www.youtube.com/watch?v=Q7Ck7BMtSPs www.youtube.com/watch?v=UR2B6f28-4E Tamping Foot Rollers
