Smart Compact (HX series)
Smart Compact is a digital compaction assistant that was developed by HAMM and which actively supports the driver. After selecting the asphalt layer to be compacted (base, binder or asphalt surface course), the required compaction energy is determined in the form of big or small amplitude, oscillation or statically, and is automatically regulated in both drums. Physical material data, such as the asphalt temperature or the rigidity value, serves as the basis for this. However, the complex cooling behaviour of the asphalt is also of vital importance. This behaviour is, on the one hand, influenced by foreseeable factors, such as the thickness of the layer or the respective mixed material, but also by unforeseeable disturbance variables, such as the air and ground temperature or the wind. Smart Compact takes these local environmental conditions and the accompanying compaction windows into consideration for the automatic regulation of both drums. This increases the process reliability and minimises the risk of surface damage. When the compaction is reaching the end, Smart Compact automatically detects that the dynamic compaction must be withdrawn. At this point, Smart Compact switches to ECO mode, reduces the engine speed by up to 20% and saves up to 15% fuel. Smart Compact therefore not only makes a decisive contribution to the compaction quality, but also to the conservation of the machine and resources. Smart Compact is available for the tandem rollers in the HX series.
