The Realtime Density Scan on Hamm’s Smart Compact Pro is a sensor that determines the asphalt density by measuring the dielectric conductivity of the asphalt mix to be compacted.

Automated compaction with Smart Compact
Despite advances in digitalization, asphalt compaction has been heavily dependent on empirical data and the experience of the driver. Consistent double passes and the correct use of dynamic compaction often depended on the driver’s knowledge.
Since 2022, the digital compaction assistant Smart Compact from Hamm has been simplifying the compaction process in asphalt construction by automatically and separately controlling the compaction modes and forces for both drums based on the selected course type — base course, asphalt binder course, or surface course. The physical properties of the asphalt, such as the temperature and stiffness, as well as the complex cooling behavior of the material, are continuously taken into account to achieve homogeneous compaction by using the optimum compaction energy and modes in each case. Local weather data can also be included as an option.
Smart Compact Pro with real-time density measurement
Hamm is now expanding Smart Compact by adding a central measured value — the real-time asphalt density sensor. This scanning sensor determines the asphalt density in real-time by measuring the dielectric conductivity of the asphalt mix to be compacted, forming the basis for the correlation with the asphalt density or the void content. Both parameters are decisive for self-monitoring or control testing. With the help of real-time density, Smart Compact Pro provides construction companies with accurate regulatory requirements.
The Realtime Density Scan can significantly reduce possible financial deductions due to insufficient quality in the construction work, and save costs for early refurbishment measures.
