Vibratory Soil Technology Removes the Guesswork.

Cat^® Compaction Control for soil compactors is a compaction measurement solution that improves quality and efficiency by providing information that allows the operator to determine when compaction meets specifications, eliminating guesswork, reducing the risk of rework and allowing the operator to quickly move on to the next job. Cat Compaction Control is factory integrated with the machine, providing greater protection for components. The solution is scalable, from a simple real time compaction measurement readout to SBAS or even RTK GNSS mapping capability. This allows the customer to purchase the system that is right for their application; or, a customer can start out with a basic system and augment it as needed.

Two different compaction measurement technologies are available: Compaction Meter Value (CMV) or Machine Drive Power (MDP).

Cat Compaction Value (CCV) is an accelerometer-based measurement system for granular soils. It is only available on smooth-drum soil compactors (CS models). Functioning while the drum vibrates, it measures deep into the ground, 1-2 m (3-6 ft), providing the operator with a picture of what is beneath the surface.

Machine Drive Power (MDP) is an exclusive technology only available from Caterpillar. MDP indicates soil stiffness by measuring rolling resistance. It is available on all Cat soil compactors–both smooth drums and padfoots. It can also be used by smooth drum machines equipped with padfoot shell kits. It is effective on all soil types, and can function when the drum is static or vibrating. MDP measures closer to depth of the lifts of materials being compacted, around 30-60 cm (1-2 ft) deep.

MDP is more flexible than CCV because it can be used on all soil types, and because it measures more shallow than CMV, which allows results to be correlated with portable measuring equipment such as lightweight falling deflectometers, nuclear gauges, dynamic cone penotrometers and plate loading devices. Because it does not require the drum to vibrate, there is less risk of decompaction when used for proofrolling.
