HAMM’s innovative density-measurement system makes compaction more efficient


The innovative Smart Compact Pro system developed by HAMM can measure density in real time as the asphalt compactor is operating. This revolutionary technology can help boost compaction productivity and quality. It ensures that there is none of the over-compaction that leads to increased fuel consumption and time worked. It also ensures that the mat meets required density specifications, boosting quality, without risking potential crushing of the aggregate. 

Crucially, this gives the mat density reading in real time. Results can be checked with a Troxler nuclear gauge for conventional working but HAMM believes that this new system will minimise the need for coring in the future, reducing costs for road construction operations. The unit can be calibrated using a Troxler system and is then ready for use.

The system can also be used alongside the firm’s existing mapping tools, boosting the quality of data collection from road construction operations.

The technology is of key importance for delivering efficient, high quality compaction according to Dr Volker Knickel, CEO of the Wirtgen Group, “The holy grail is to measure density.”

    Effective compaction control is one of a series of technical innovations boosting performance efficiency – Mike Woof writes. Maximising compaction efficiency can be a major cost factor on construction projects. Both for soil and asphalt compaction sectors, the risk from leaving an area under or over-compacted is substantial.
