The MOBA Compaction Assistant paves the way to controlled compaction in road construction

MOBA monitoring system for rollers

Limburg, (PresseBox) - "To repair winter damage on German freeways and federal roads, we will spend 2,200 million Euros this year" - Announcement by Peter Ramsauer, Federal Minister of Transport, January 2011. The potholes and cracks that many roads exhibit after periods of frost are often caused by inadequate quality of the sealed road surface. To achieve a satisfactory result in road construction, the compaction of the material is a critical parameter, as is the temperature. An exact compaction makes the asphalt structure homogeneous, which prevents road damage and premature wear and tear.

With the Compaction Assistant (MCA), an application for rollers, MOBA Mobile Automation AG in Limburg/Lahn provides the necessary equipment to achieve optimal compaction of material in the construction of roads and tarmac surfaced areas. The MCA monitoring system consists of an antenna, controller and display and supports the vehicle operator by recording the number of roller passes during the entire project and by reconciling target and actual passes. If the vehicle stops, the MCA stores the position with centimeter accuracy so that operations can resume exactly from where they stopped. The Compaction Assistant allows the evenly distributed passes over the entire surface to meet the specified compaction. This permits production of a homogeneously compacted material, preventing future road damage.

Precise acquisition within centimeters

GNSS-SBAS signals supply exact position information for the roller, considerably increasing the accuracy of the work processes. The controller gathers and stores all important data such as position, number of passes and temperature of the material used. The aggregated data is directly sent to the machine operator and visualised on a graphics display in the vehicle cab. Both the display and the applications can be designed individually to customer specifications.

More efficiency, less wear

The Compaction Assistant permits a highly efficient deployment of the roller and reduces both operating cost and wear on the machine. Apart from the application of tarseal surfaces, the Compaction Assistant also offers accurate support in the construction of base layers for the road bed to achieve optimum results in the compaction of the materials.
