After the steel drums have densified, pneumatic rollers make the pavement last. Cat® pneumatic rollers use rows of oscillating rubber tires to seal and smooth asphalt surfaces, creating water resistance and durability that stand up to traffic and time.
Engineered for a Uniform, High-Density Finish
In asphalt paving, density is just the starting point. You also need a sealed surface that keeps water out. Water causes potholes, cracking, and early pavement failure. Our pneumatic rollers for sale solve this problem.
Their flexible rubber tires apply a unique kneading action that achieves density while sealing the surface. They press aggregate particles tightly together and force out trapped air voids. As a result, the pavement resists water infiltration and lasts significantly longer.
Kneading Action Edge for Superior Seals
Pneumatic tires are different from steel drums. Air-filled rubber is flexible, so it conforms to the surface texture and applies consistent pressure across the entire contact area. As the roller moves, the tires exert both vertical pressure and a horizontal walking or kneading action.
This gentle pushing and pulling rearranges asphalt components into a denser configuration while maintaining aggregate integrity. The result is a smooth, impermeable surface.
Flexible Ballast for Precise Control
Every mix is different. Some require more compaction force, while others need a lighter touch. Cat pneumatic rollers feature an adjustable ballast system that gives you precise control. Add or remove modular steel blocks or water tanks to match the exact weight your specific mix design and job conditions demand.
What this means for your business is that you work multiple applications and materials with a single machine. Operators achieve optimal density on the first pass. Fuel consumption stays efficient.
Overlapping Tires for Full Coverage
Our machine’s tire configuration prevents density gaps. The tires are offset so the front tires cover the gaps left by the rear tires. Add all-wheel oscillation and vertical suspension into the mix, and every tire maintains optimal contact with the ground, even over minor surface irregularities, for uniform compaction across the full width of every pass.
Applications of Pneumatic Rollers
The main application of pneumatic rollers is surface sealing. They are partners to tandem vibratory rollers. After steel drums provide initial density and smoothness, pneumatic rollers seal the surface for maximum durability.
You can also have them test the sub-base. Pneumatic tires can reveal soft spots that rigid steel drums might bridge over and miss. This capability helps catch problems before they become expensive failures.
