Accurate density measurement from HAMM

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.”

    Advances in asphalt plant technology were in major evidence at the bauma 2016 exhibition in Munich - Mike Woof writes One of the most apparent developments at bauma 2016 was the strong focus on asphalt plant technology. The massive physical presence of the asphalt plants could be seen from a distance, right across the showground, particularly the 50m-high machine Benninghoven had opted to exhibit. However, other plant systems from rival firms Ammann, Lintec and Marini, as well as Turkish company E-MAK, c

  • The Path to Climate-Neutral Road Construction
    October 1, 2023
    Machine manufacturers and construction companies around the globe are currently searching for ways to achieve the goal of climate-neutral construction. The challenge here is to successively reduce emissions of CO2 and other harmful gases (summarized to CO2 equivalents: CO2e) around the world to zero over the coming decades. In the road construction sector, this transformation is inextricably linked to the improvement and further development of production and working processes. In the future, machines and construction materials will also be assessed based on the climate-harmful emissions arising from their production and use. However, the focus should not be on individual machines, but on the entire process leading up to the finished product – a road. Ultimately, the decisive factor is the emissions generated per kilometer of newly built or rehabilitated road – the “CO2e per work done”.
