Smart Compact for asphalt construction

Digital assistant for increased process reliability: For asphalt construction, HAMM has developed the digital compaction assistant Smart Compact. It actively supports drivers in selecting the right settings for compaction. The driver specifies whether a base, binder or surface course is to be compacted. The assistant automatically calculates the type of compaction required and the necessary compaction energy.

Automatic selection of compaction force and mode

Smart Compact also automatically selects the appropriate type of compaction: Static, with oscillation, with vibration and small amplitude or with vibration and large amplitude. The settings for each drum are set individually.

This is controlled on the basis of physical material data, such as the asphalt temperature and the rigidity value. Also of particular importance is the complex cooling behavior of the asphalt. It depends on known factors such as layer thickness or the type of mixed material. It is also influenced by unforeseeable variables, such as the ambient temperature or the wind. This information can be captured by a weather station on the roller itself and therefore factored into the settings.

All these framework conditions create a compaction window for efficient and high quality compaction. Smart Compact takes into account these influencing factors, including the local weather conditions, when automatically regulating both drums. This increases the process reliability and minimizes the risk of surface damage.

Smart Compact is available for the tandem rollers in the HX series.

ECO mode included

When the compaction is reaching the end, Smart Compact automatically withdraws dynamic compaction and works in ECO mode. It does this by reducing the engine speed by up to 20%. This saves up to 15% fuel. Smart Compact therefore not only makes a decisive contribution to the compaction quality, but also to the preservation of the machine and resources.

Smart Display and on-board computer in one

Smart Compact is operated via a separate display that also functions as an on-board computer. The display indicates fill levels, operating hours and weather data, such as humidity, wind strength, wind direction and air pressure, among other data. What’s more, the brightness and language of the display can be adjusted and the display can switch between day mode and night mode.

The benefits of Smart Compact at a glance:
  • Homogeneous compaction
  • No under-compaction or over-compaction
  • Less surface damage
  • Increased user safety which means increased quality
  • Lower CO₂ emissions and lower diesel consumption
  • A more comfortable experience for operators
  • Support for inexperienced drivers (little previous knowledge required, intuitive operation)
  • Reduction in double passes
