Spotlight on Digitalization: Extensive Range of Products for Earthworks and Asphalt Construction

Roller manufacturer Hamm presents digital solutions for road construction and earthworks at ConExpo 2026 in Las Vegas. 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 assortment are the products Smart Compact Pro, Smart Compact for earthworks, Track Assist, and WPT Compacting.

Smart Compact Pro: Automated Compaction Based on Real-time Density

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 reducing the work involved in removing drill cores. With the help of the new Realtime Density Scan sensor, the density is still precisely calculated in real time, even for static compaction. Until now, real-time density had been the missing piece of the asphalt compaction puzzle, which is now provided by Hamm in the form of Smart Compact Pro. Another benefit: The system is quick and easy to calibrate using a conventional measuring probe. With WPT Compacting, operators also have 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 the tandem rollers in the HD+ and HX series.

Automated Compaction with New Compaction Measurement System is Also Available for Earthworks

Smart Compact is also the main focus of automated compaction in the earthworks sector. To demonstrate this, Hamm brings the HC 200i C VA compactor to Las Vegas. 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). The models in question, available in weight classes of 28,660 lbs, 44,092 lbs and 55,115 lbs (13 t, 20 t, 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. The direct adjustment of the amplitude also effectively prevents jump operation and over-compaction, at the same time as protecting the machine and its operator from mechanical loads. What’s more, it makes the VA drum an energy-efficient system overall.

Track Assist: The Digital Assistant for Roller Drivers

The new Track Assist app for Android is the next phase in the development of the Smart Doc app and offers drivers an improved driving experience for 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.

WPT Compacting: Efficiency for Site Managers and Foremen

With WPT Compacting, Hamm provides a high-performance tool for monitoring, documenting, and analyzing operations on construction sites. All process data – including the real-time density from Smart Compact Pro – is channeled into the central construction site and fleet management tool from the Wirtgen Group, the John Deere Operations Center™, for accurate analysis and visualization in a variety of views. Another feature is machine communication between both rollers and and pavers.
