Software helps ensure optimum compaction
01 April 2007
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, says a spokesman for the Sweden-based manufacturer.
The Dynapac Compaction Analyser for Asphalt (DCA-A) will be launched at this month’s bauma construction equipment show 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,” says the spokesman. “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. 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.
