Dynapac’s new control and documentation system is built up in two levels: • The first level is the Compaction Meter, now using Evib readings for both soil and asphalt. o On asphalt rollers this is supplemented by the Asphalt Temperature Meter. It utilizes two temperature sensors, one at each end of the rollert to register the surface temperature oft he asphalt. The temperature is measured by the sensor that is currently at the front depending on the driving direction in order to minimize the influence of surface water from the drum sprinklers. • The second level of the system is the Dynapac Compaction Meter plus the Dyn@Lyzer with GNSS (Global Navigation Satellite System). o This registers all the Compaction Meter data and continuously displays the compaction results to the operator on the computer screen. The data is, at the same time, recorded and saved allowing full traceability and quality assurance. The GNSS receiver (such as GPS, GLONASS, Galileo, etc) gives the precise position of the roller on the job site at all times. The level of accuracy depends on site requirements.

Dynapac’s documentation system that records and maps stiffness and stiffness progress of the compacted layer in real-time as well as temperature and number of passes. A GNSS receiver is used for positioning. Positioning accuracy may be selected between Differential-GNSS (decimeter accuracy) or RTK-GNSS (cm accuracy) depending on site requirements The Compaction Analyzer can be used as quality control and assurance tool as well as a production tool to optimize the compaction effort. Compaction Analyzer Multi is be used when two or more rollers are working together in the same layer. All machines that are connected get near real-time update on the total number of passes that were med etc. Connection is made over short-range wireless communication The Dyn@Lyzer can be used in one or more of the four ways described below: - Compaction to a target value requires calibration. - Compaction to a target compaction progress, relative increase between two consecutive passes. Calibration is not required. - Counting number of passes, vibratory as well as static. Calibration is not required. - Localization of weak areas for acceptance control or additional action (Only for soil) Benefits when using Dyn@Lyzer:
