Product Overview
Model: Three-sided Impact Roller | Category: Foundation Construction Equipment
The Impact Compactor Roller is a three-sided polygonal impact roller designed for rapid compaction of large earthfill areas. Towed by a heavy tractor, its non-circular drum generates repeated impact forces that reach deep into fill layers, achieving superior compaction in a single pass compared to conventional smooth-wheel rollers. Widely used in embankment dams, highway subgrades, and airport runway foundations.

Construction Class
1. 30 kJ Towed Impact Energy
The three-sided (trilateral) drum is towed at 10–15 km/h by a 235 kW tractor, and its non-circular shape delivers a 30 kJ impact with each revolution—far more per pass than a smooth-wheel roller.
2. Rapid Area Compaction
Because one towed pass replaces many roller passes, the impact roller compacts large earthfill areas fast—embankment, subgrade and runway fill—at a fraction of the time of conventional compaction.
3. Deep Reach in a Single Pass
The repeated impact transmits stress deeper than static vibratory rollers, reaching well into the fill layer to reduce settlement and improve uniformity across large areas.
4. Simple, Towed and Productive
No engine on the drum itself—it is towed by a heavy tractor—so maintenance is simple and the machine covers ground at speed, ideal for long highways and large earthworks contracts.

About the Impact Compactor Roller
The impact compactor roller is for fast, large-area earthfill compaction. Towed behind a heavy tractor, its three-sided drum slams into the ground on every revolution, densifying embankment fill, highway subgrades and runway bases in far fewer passes than a smooth roller.
It is the productivity choice for long linear projects—highways, railways, airfields and dam embankments—where many kilometres of fill must be compacted to specification quickly. The impact reaches deeper than static compaction, improving uniformity and cutting future settlement.
For contractors on infrastructure programmes, the impact roller converts otherwise slow rolling into high-throughput earthworks. Yutong supplies the towed roller and advises on speed, pass count and lift thickness to meet your compaction specification.
Yutong supplies the towed impact roller with the matching tractor specification, a pass-count and speed guide, and a wear-parts list. For long highway and airfield contracts, it converts slow rolling into high-throughput compaction.
Yutong ships the impact roller with a matching tractor specification, pass-count guidance and wear parts, turning long highway and airfield earthworks into fast, predictable compaction cycles.
Because the drum has no engine of its own, service is limited to tyres, bearings and the towing hitch—a simple, low-cost setup for contractors running long linear earthworks programmes.

View DetailsWhat is an impact compactor roller?
It is a towed three-sided drum that drops a 30 kJ impact on each revolution, compacting large earthfill areas in far fewer passes than a conventional smooth-wheel roller.
How fast does it work?
The optimum towing speed is 10–15 km/h, so it covers long subgrades and embankments quickly—one pass replacing many roller passes.
What does it compact best?
Embankment fill, highway subgrades and runway bases over large horizontal areas. It complements deep dynamic compaction rather than replacing it for very thick problem layers.
What tractor do I need?
A heavy tractor around 235 kW is recommended to tow the 16.2 t impact drum at the correct speed; Yutong can advise on the matching tractor specification.
How does it compare with a smooth roller?
It delivers more energy and deeper reach per pass, dramatically speeding up large earthworks; smooth rollers are still used for fine finish and small irregular areas.
Where is it most used?
Highways, railways, airfields and dam embankments—long, linear, high-volume compaction contracts where productivity is the deciding factor.
