Compaction- Pneumatic Tired Roller Pneumatic tired roller has a number of rubber tires at the front and at the rear end.  Empty spaces left in between the two tires that make 80% coverage area under the wheels. Pneumatic roller has the ability to exert contact pressure ranges from 500 – 700Kpa. Pneumatic tired roller can be used for highways, construction of dams and for both fine grained and non-cohesive soils.
Compaction- Smooth wheel roller Smooth wheel roller has no vibrator attached with the drum. This makes smooth wheel roller best suited for rolling of weaker aggregates, proof rolling of subgrades and in compacting asphalt pavements. Compaction of clay or sand is not a good choice to done with smooth wheel roller. This is so, because there are many empty voids in clay soil and sand, which cannot be minimized without vibrators.

Compaction: Tamping roller Tamping foot roller consists of four wheels and on each wheel kneading boots/feet are fixed. Tamping roller has more coverage area i.e., about 40- 50%. Contact pressure of tamping roller varies from 1400 – 8500KPa. It is best dedicated for fine grained soils. Intro, Coverage

Compaction- Vibratory Roller Vibration is to reduce the air voids and to cause densification of granular soils. During vibration of soil layer,  rearrangement of particles occurs due to deformation of the granular soil because of oscillation of the roller in a cycle. Rubber Tires, Particles
