Guaranteeing optimum compaction quality.

Continuous compaction control with HCQ GPS Navigator

Soil and asphalt compaction aim at creating a structure that is as even, durable and stable as possible. Hamm uses HCQ – short for Hamm Compaction Quality –, a specially developed measuring and documentation system, to improve compaction quality and achieve optimum compaction results.

Real-time measurement readings

The module used for continuous compaction control in earthmoving operations is the HCQ GPS Navigator. The system evaluates the entire compaction process and bearing capacity achieved during the operation of the single-drum compactors. The most important parameters – density and bearing capacity – can thus be monitored and optimized in real time during the compaction process.

Positioning by means of GPS

Sensors at the roller’s drum continuously measure the bearing capacity achieved during the compacting operation. The measured values are then combined with the position data from a GPS receiver located on the roller. The resulting values are displayed to the roller driver as a clear graphical map on a large screen inside the driver’s cabin.

Efficient increase in density

On the screen, the roller driver sees both the current compaction efficiency and number of roller passes achieved, which helps him to quickly identify those places that require further compaction. This feature not only prevents excess compaction but also results in significant savings of fuel and time.
