Dynapac is launching new software for the optimisation of asphalt compaction. The software runs on a cab-mounted computer, helping operators achieve the ideal rolling pattern by keeping track of the number of passes and showing temperatures in the asphalt. The Dynapac Compaction Analyzer for Asphalt (DCA-A) will launch at Bauma as an option for the newly-launched CC424, CC524 and CC624 articulated tandem rollers. It can also be retrofitted to older machines. 

The introduction of DCA-A follows the successful launch in 2004 of similar software for use in soil compaction. DCA-A has been developed to give operators real-time information about the rolling, enabling them to plan their next passes taking account of the current temperature of each area. Tracking the number of passes makes it easy for the operator to maintain control of the pattern and achieve the best results. Better planning of the rolling operation also ensures jobs are carried out more efficiently resulting in using less fuel. With DCA-A, operators can see the results on the coloured graphical display, highlighting at a glance which zones need further compaction. Without DCA-A, they have to remember in detail how many passes have been carried out in each area. The system is used in conjunction with a global positioning system (GPS) to track the machine’s location, enabling accurate recording for each section. DCA-A incorporates readings from temperature sensors at different spots around the roller. Keeping tracking of the temperature guides the roller operator to work in critical areas, which are cooling off and avoid those that are still too hot for compaction. The system provides full documentation of the compaction work carried out, meeting quality assurance demands as well as providing information for feedback and review. 

DCA-A runs on a heavy-duty rugged laptop, ideal for use in site conditions. It is mounted on a bracket in the upper left part of the cab, giving clear visibility for operators and easy control via a touch screen. The system works with a range of popular GPS equipment so that customers can use their existing receivers. There is no need to have a separate computer for every roller as the laptop can be moved from one docking station to another. Operators can use DCA-A in conjunction with Dynapac’s well-established PaveComp software to calculate the number of passes needed to achieve the right density for a particular mix. DCA-A can also be used in conjunction with test strip and core data to verify the rolling procedures before starting on the main areas. Incorporation of a USB port in the laptop facilitates easy transfer of the data back to the main office computer. Future methods will include the use of a radio modem. The system also has the potential for communication between more than one machine.
