SOIL COMPACTORSREXPACTOR™ SP-3 / SP-5 / SP-8
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
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
In a typical operation, old fashioned style tractors, frequently plagued by the uncompacted ‘windrow’ of materials between the only two wheel paths, risk high centering of the machine, losing traction and getting bogged down in the uncompacted soil. This presents a significant operational limit to the machine. To address this limitation, makers of the old-style tractors fit the machine with wider high flotation wheels attempting to strike a balance between the reduction of compaction force produced by wider wheels and the risk of getting stuck in the soil.
The RexPactor’s close, inset front wheels compacts the center line swathe of soil, greatly reducing the risk of getting high centered. This full width compaction, combined with high distributed load (measured in pounds per linear inch or PLI), means that the RexPactor achieves the most efficient compaction in a single pass of any soil compactor.
Unique four wheel configuration for effective full width compaction.
OLD-STYLE TRACTORS
COMPACTION FORCE
Compaction is as much about how a machine applies force – Distributed Load measured in pounds per linear inch or PLI (N/m) – as how much the machine weighs.
PLI is calculated by dividing total machine mass in pounds (Newtons) by the combined effective width of all four wheels in a single pass, in inches (meters). Generally speaking, the higher the PLI (N/m), the more material will be compacted in the same space, resulting in a greater density and improved productivity.
