Roller manufacturer Hamm presented digital solutions for road construction and earthworks at Conexpo 2026. The portfolio incorporates technologies and products that automate and simplify compaction processes, and set new benchmarks in quality, efficiency and process reliability. At the heart of this offering are Smart Compact Pro, Smart Compact for earthworks, Track Assist and WPT Compacting.
Smart Compact Pro and Smart Compact
With Smart Compact Pro, Hamm becomes the first manufacturer in the world to integrate real-time density into the automated compaction process. The new technology will significantly increase the quality of asphalt compaction and the service life of roads, while simultaneously lowering the long-term costs of road construction and renovation. Smart Compact Pro also ensures that compaction targets are achieved with precision, reducing the likelihood of additional expenditure as well as minimising the work involved in removing drill cores.
The new Realtime Density Scan sensor enables precise, real-time density calculation, even during static compaction. According to Hamm, real-time density had previously been the missing piece of the asphalt compaction puzzle, which is now provided by the manufacturer through Smart Compact Pro. Another benefit is that the system is quick and easy to calibrate using a conventional measuring probe. WPT Compacting also equips operators with a tool to document real-time density data for an in-depth analysis of all performance and machine data. Smart Compact Pro is available for tandem rollers in the HD+ and HX series.
Meanwhile, Smart Compact plays an important role in automated compaction for earthworks. To demonstrate this, Hamm brought the HC 200i C VA compactor to Conexpo. By virtue of an infinitely variable amplitude and a newly developed compaction measurement system, Smart Compact allows compactors to perform automated compaction to the new target value in MPa (MN/m²). The models in question – available in weight classes of 13 t, 20 t and 25 t – not only offer reliable and homogeneous compaction, but also help to make building projects more cost-effective by reducing the number of double passes and lowering diesel consumption. In addition, the direct adjustment of the amplitude effectively prevents jump operation and over-compaction, while protecting the machine and its operator from mechanical loads. What’s more, it makes the VA drum an energy-efficient system overall.
Track Assist and WPT Compacting
The new Track Assist app for Android marks the next phase in the development of the Smart Doc app and offers drivers an enhanced experience in asphalt construction and earthworks. It provides information on important compaction parameters, such as double passes, real-time density, temperature limits, changes in compaction value, reversing points or the proportion of jump operation. In the next stage of development, Track Assist will become a fully-fledged assistance system that allows operators to compare compaction targets with up-to-date actual results.
With WPT Compacting, Hamm provides a high-performance tool for monitoring, documenting and analysing operations on construction sites. All process data – including the real-time density from Smart Compact Pro – is channelled into the central construction site and fleet management tool from the Wirtgen Group, the John Deere Operations Center, for accurate analysis and visualisation in a variety of views. Another feature is machine communication both between rollers and between rollers and pavers.
