EquipmentWorld.com | April 2015 87 ATLAS COPCO Atlas Copco introduced the Dynapac CC1300 articulated compact tandem roller at the show. Like the CC1100 and CC1200, this new model comes in a dual-steel vibratory drum configuration (front and back), or a combination option of one vibratory drum and four rubber tires. In addition to being used for asphalt compaction, the 45-horsepower CC1300 can also be used for compact- ing sub-bases and base courses. The rollers for all three models feature water tanks made of cor- rosion resistant recyclable polyethylene plastic. They also have three separate filters to prevent clogging in the sprinkler nozzles, and the sprinkler system can be drained without the use of special tools. Operators can compact materials close to high curbs because of the high clearance of the drum's edges. On the combination models, the rubber tires are driven in pairs by separate drive motors, a feature the company said cuts down on marring during sharp turns on fresh asphalt. As with other new Atlas Copco equipment, all three models offer a sideways sliding seat and dual front and reverse controls. Atlas Copco also showed their new intelligent compaction system, which offers a touchscreen tablet interface that is wire- less and has a 12-hour battery life. Atlas Copco's CC2200 through CC6200 asphalt rollers and their CA2500 through CA6500 soil rollers can be outfitted with the system. The company's dealers also are providing free training for contractors. The system provides real-time stiffness measurements of soil and asphalt via a drum-mounted accelerometer, while front-and rear-mounted sensors provide asphalt temperature readings that help in pro- viding consistent stiffness measurements. Pass counts also are measured. The system keeps up with the number of completed passes via GPS and cross-references this information with how loose the material is, which helps determine when compaction is complete. The operator is alerted when compaction is complete, which in turn minimizes over compaction. Data collected can be saved and used for analysis later, or for Federal Highway Administration inspections.
