What can you do with a pneumatic roller?
Pneumatic rollers offer versatility not available with a steel drum roller. The weight of the machines and air pressure of the tires can be adjusted to meet the specific pressure desired on a particular job. “You are either going to adjust the tire pressure and/or you are going to increase or decrease the weight of the machine,” says Cole.
Why are pneumatic rollers used in Superpave?
Pneumatic rollers have become more popular with stiffer mixes, such as those used in SuperPave, since it can help you achieve compaction density. “Traditional steel drum rollers may tend to push this material as opposed to compacting it.
How does a pneumatic roller work in a pothole?
By having all-wheel independent movement, the pneumatic roller is able to dip down into a pothole and compact it much more thoroughly, Chastain says. “No matter what the contour of terrain on the work surface, the pneumatic roller is going to be able to get a more consistent compaction density across the entire work surface.”
How are pneumatic rollers different from steel drum rollers?
Unlike steel drum rollers, pneumatic rollers are able to conform to the surface being paved. “Rubber tires that are air inflated and have some give conform to the work surface whether it is rolling stone or asphalt,” says Shannon Chastain, owner of Basic Equipment.

How many tyres are on a pneumatic roller?
The pneumatic roller is rubber tyred instead of steel tyred or drums and feature two tandem axles, with three or four tyres on the front axles and four and five tyres on the rear. The tyres are mounted in pairs that can oscillate, so tyres can move down into soft spots that would be the barrier for a steel drum.

What can pneumatic roller compaction equipment be used for?
These type of compaction equipment are suitable for soft base materials or layers of loose soil and closely grained sands. It can be used for compaction of the cohesive soils with the moisture content of 2-4% below the plastic limit. It is very effective for bituminous layers where the design mix has a high content of fines.
