Hamm Smart Compaction

Higher quality, lower costs: Hamm Smart Compaction

In its Smart Compaction product range, Hamm provides intelligent solutions to take the hard work out of compaction, compaction measurement and compaction documentation.

In a bid to increase the process reliability and quality of compaction, Hamm has developed a range of different digital solutions. Firstly, in the form of their free Smart Doc app for Android, the roller manufacturer is providing a modern tool for continuous compaction measurement and documentation in asphalt construction and earthworks. Secondly, Smart Compact has been developed to act as a digital compaction assistant, actively supporting the driver to select the right compaction energy. Both solutions not only ensure high-quality compaction, but also conserve valuable resources.

Smart Doc records the speed, the frequency, the amplitude, the proportion of jump operation and the achieved compaction value (HAMM Measurement Value), and can create test reports on demand for reliable and accurate basic proof of continuous compaction control. The number of double passes is also documented in the process.

Smart Doc from Hamm: Process optimization and compaction documentation

Another easy-to-integrate and user-friendly digital solution is Smart Doc from Hamm. The app records the most important parameters during the compaction, and combines these with the position data generated by the smartphone or a smart receiver (optional). These are then displayed together in a real-time visualisation on the end device. This easy-to-interpret visualisation shows the user at a glance where compaction is still required and which areas have already been sufficiently compacted – especially useful when training inexperienced drivers.

However, the compaction progress is not only visualised, but also documented with every parameter collected and, upon request, can be collated in an easy-to-read compaction report. This compaction report can then be shared with third parties. As such, the app fulfils the minimum requirements for continuous compaction control (CCC). Another benefit: When the information in Smart Doc is strictly followed, the number of passes is also optimised. Up to 30% of double passes can be avoided – saving fuel and therefore CO₂.

A quick description: Smart Doc

The smartphone app (available free from Google Play) displays the compaction status in the form of graphics on a smartphone or tablet, and keeps the driver informed during compaction, indicating where and to what degree the substrate has been compacted. After completing the compaction, a compaction report can be generated and shared at any time.

Currently, Smart Doc can be used and retrofitted in the following Hamm series: HC CompactLine, HC, HD+ and HX. The app is free and can be installed through the Google Play Store on all Android smartphones and tablets from Android 6.0 and is available in German, English, Spanish and French.

Smart Compact from Hamm: The smart compaction assistant

With its Smart Compact digital compaction assistant, Hamm becomes the first manufacturer in the world to automate the separate adjustment of both drums, while also increasing process reliability and raising compaction quality to a new level.

The Smart Compact digital compaction assistant actively helps the driver to set the correct compaction energy in terms of larger or smaller amplitude, oscillation or static compaction and controls this in both drums. Then, before they start compacting, the driver simply has to select whether they are compacting a base, binder or asphalt surface course. Smart Compact takes care of the rest. The system does this by evaluating different physical properties of the asphalt, such as the temperature or rigidity. It also takes into account the complex cooling behaviour of the asphalt. Additionally, a weather station can be integrated as an option, allowing local weather data to be factored in. Smart Compact takes all this information and calculates the right compaction settings, with separate values for each drum. This makes it unparalleled in the world, and contributes to a safe compaction process and high-quality results. Smart Compact is available for the HX series tandem rollers.

Intelligent control saves fuel

Equipped with various input parameters, Smart Compact recognizes when dynamic compaction is no longer advisable – for instance, if the asphalt temperature is too low. The system then automatically cancels the dynamic compaction and puts the roller into ECO-Mode, which reduces the engine speed by up to 20%. This action not only lowers the fuel consumption by up to 15%, but also extends the service life of various components in the machine.
