The most common method for soil compaction combines the single-cylinder roller with a padfoot drum whenever necessary.
But in recent years, the compacting technology has developed new ideas and methods to increase the benefits, features and speed of work.
Using pneumatic tire rollers for this type of work is an old practice, but not many companies are familiar with the benefits it delivers.
The ccr 21.35 is the most powerful roller in the world, especially for soil compaction.
It provides compaction with 5,000 kg load per wheel and over 6.5 kg/cm2 pressure. This means the compaction bulbs are wider and deeper with the kneading effect, which ensures the compaction of thicker or finer soil courses with fewer runs compared to any other machine.
This is suitable for any soil compaction work that cannot be performed by any other currently available roller, with unsurpassed results thanks to an even higher pressure.
It can be used with treaded tires to compact clay and clay-loam type of soils. The tires, similar to a padfoot drum, feature a tread pattern on the rubber to limit contact surface and ensure the highest possible pressure on the course.
The tires can penetrate to the bottom of the course to deliver a compacting effect going from the inside to the outside.
The pressure applied on the surface with this type of tire can reach up to 9 kg/cm2 –this is unparalleled by any other roller.
In terms of load per axle for a drum, it would mean exceeding 120 kg/cm on its front and back axles.
