EquipmentWorld.com | March 2018 45 "Track pavers are used any- where you have bad bases and also when you're doing wider- width paving," says Jon Ander- son, Caterpillar's global sales manager for pavers. "The wheel pavers are great for repair work and mill and fi ll jobs. They work great in situations where you're paving over asphalt that's been milled out, and you've got a good solid base there, no traction issues, and you're generally not going wide width." Wheeled pavers offer an advantage for multiple short paving jobs or patches in a particular vicinity, as they are more mobile and can be driven from one spot to the other faster than a tracked paver, especially if the tracked machine must be trailered, according to Vögele. With mobile track machines, traditional speed differences between wheel and steel track machines have been greatly reduced to the point where it has almost no impact on typical paving operations, Anderson notes. "It used to be that wheel machines were about three times faster than track machines, but now with mobile track pav- ers that's down to under 40 per- cent faster," he says. "When you look at how far most people drive a machine, it doesn't add much to the day." Both tracked and wheeled machines adapt well to their situations, so often the decision comes down to price. Wheeled pavers cost less to buy and maintain, Donovan and other experts say. Anderson estimates that a wheeled paving machine costs roughly 15 percent less than tracked machines. "You can eat that up fast if you're getting stuck often," he says. But if the wheeled version does the job for you, Here's a sampling of the wheeled and tracked pavers on the market: Ammann Ammann Group recently launched a diverse paving line that includes 17 models with both tracked and wheeled versions. Screed options include tamping/vibrating, high-compaction and rigid-frame. The machines come in three sizes: compact pavers, including the mini pav- er; the city pavers; and the biggest group, the large pavers. Amman's large pavers can reach production of 1,100 tons an hour with maximum widths of 15.31 yards. The pavers are available with conventional controls or with the advanced PaveManager 2.0 system. BOMAG/Cedarapids The BOMAG Cedarapids CR662RM RoadMix material transfer vehicle (MTV) and paver combo machine has a 260-horsepower Tier 4 Final Cummins engine. The CR662RM can be converted from an MTV to an asphalt paver in less than four hours by removing the rear conveyor assembly and replacing it with a screed, the company says. The rubber-tracked CR662RM features a 21-pound-per-square-inch fully loaded ground contact pressure that can cross bridges fully loaded and can be transported to a jobsite the same way as a 10-foot paver. The Remix Anti-Segregation System delivery augers feature hard-faced back sides and pitch spacing transitions ranging from 10 inches at the front of the hopper to 12 inches at the back. The throughput capacity can exceed 500 tons per hour in both the paver and MTV confi gurations. Dynapac North America The FC1600C is a crossover between commercial class paver and highway class paver, showcasing what Dynapac calls its "designed to perform and built to last" philosophy. It's a rebuildable paver with wear-resistance replace- able conveyor fl oor plates, segmented auger fl ights and bolt-on screed plates, the company says. With hydraulic screed crown, hydraulic extension slope and match- ing height, and hydraulic tow point, the paver can be easily adjusted for varying road profi les. The Dynapac VF0816C screed on this paver weighs about 4,500 pounds, provid- ing the best pre-compaction of a paver in its class, Dynapac says. The unique 4-auger system mounted on the screed also allows a 15.5-foot paving width without adding ad- ditional auger extensions or without shoveling the material when paving wide widths. The 99-horsepower Cummins engine has a 16-kilowatt hydraulic driven generator, providing uniform heating throughout the width of the screed to achieve perfect mat texture, Dynapac says. Caterpillar With Econ mode, the AP10055F has an engine speed of 1,650 rpm and trims fuel use by up to 15 percent over Cat E-Series pavers, while also lowering sound. More ac- curate control maximizes mix utilization and saves money. There's true averaging with sonic sensors that use fi ve transducers; two readings are discarded and three averaged. A 10-point auto-calibration eliminates over- and underadjustment from a single calibration point. Cross-coupling, slope and elevation are maintained with height adjustments.
