Soil Compactors

Available in three sizes, the RexPactor™ is a high speed soil and embankment compactor with features that can deliver the high quality soil substructure qualities necessary for long lasting structures sought after by todays infrastructure designers.

Crucial to the stability and longevity of roadway, pipeline and other soil embankments is the proper preparation of the subgrade level of the structure. CMI RexPactors are an important tool to civil and energy infrastructure builders around the world to ensure the high performance of these structures.

Today’s surface transportation infrastructure, designed and largely built decades ago, is carrying volumes of traffic and carrying weights that weren’t necessarily anticipated in those times. With population and economic growth, truck traffic will continue to grow with cargo weights ever increasing along with the number of passenger vehicle miles traveled. These unrelenting pressures will exert ever higher forces on both concrete and asphalt roadway surfaces.

Roadway surface failure analysis reveals that a vast majority of failures such as cracking, pavement rutting and ‘pot-holes’ actually originates from the sub-structure. A key step in ensuring that the sub-structure can retain the proper strength to support the roadway pavement structure, as well as the designed traffic load, is properly compacting the load bearing soil lying beneath.

The solution to achieving high density and uniformly compacted soils is the CMI RexPactor™, the industry’s only full width soil compactor utilising all four wheel paths in a single pass. All other soil compactors based on old fashioned style tractors leave an uncompacted center-line swathe between the two wheel paths resulting in increased passes, fuel consumption & reduced machine life, while also making them unusable in confined areas such as trench pipelines.

  • Unique wheel arrangements resulting in the industry's only full width soil compactor
  • Exclusive open ring design; self cleaning wheels compact from the bottom up
  • Side facing seat for operator comfort and excellent visibility in forwards or reverse
  • Purpose built high speed soil and embankment compactor for infrastructure projects

Features

Open Ring Wheels

The CMI RexPactor™, which achieves very high and uniform densities through ‘bottom-up’ compaction, is fitted with unique ‘open-ring’ high strength fabricated steel wheels. Bottom-up compaction is achieved by forcing the wheel rings to sink into the soil under the machine’s static weight.

Forcing the compaction pad-foot deeply into the soil lift to the point of refusal, avoids the false refusal or flotation that would otherwise occur with other drum style or closed-ring wheel designs.

Full Width Compaction

The RexPactor’s close, in-set front wheels compact the center-line swathe of refuse, greatly reducing the risk of getting high-centered.
