If contractors are push- ing up a high grade, with soft sub-bases, or are out West, they may want the tracked machine, Donovan says. But customers primar- ily doing highway work could opt for the wheeled machines, relying on the six-wheel-drive option for grades, which all manufac- turers offer. State-by-state preferences With manufacturers having tackled problems with trac- tion and maneuverability, differences often simply boil down to what contrac- tors are used to and prefer, Holland says. There are regional differ- ences in those preferences, but they're spotty and it is really more state-by-state, Anderson says. "West of the Mississippi, you don't see too many wheeled pavers." And even within states, there can be differences. For example, in Texas, some areas lean toward wheeled machines and oth- ers toward tracked, Holland says. "Some of it is due to the type of paving. A lot of it is tractive effort of the track machine. And then you look at how they're paving. Are they paving on base mate- rial, dirt or CTB (cement- treated base)?" With base material, the ground pressure of the tracked machine is spread more evenly over the length and width of the tracks; whereas, with a wheeled machine, that ground pressure is on the highway contractor | continued LeeBoy One of LeeBoy's most popular wheeled pavers is the 6150. With a quicker travel speed, this machine delivers a quality mat while easily maneuvering from point to point, LeeBoy says. It has a 74-horse- power Kubota Tier 4 Final engine, with a variable paving width of up to 15 feet. Paving speed is 2.6 mph and travel speed is 7.5 mph. Operators can choose a high or low deck confi guration, which can improve visibility de- pending on the application. The 6150 comes with dual electronic steering wheels and sliding operator control. The machine has a 7-ton-capacity material hopper and propane or electric (option) screed heat. It's 16 feet, 6 inches long. Transport width is 8 feet, 6 inches or, with the hopper wings down, 10 feet, 7 inches. Total weight is 17,550 pounds. LB Performance The PF150D and the PF161C are wheel- type pavers with 110-horsepower Cum- mins engines. The PF150D has a 74-horse- power Kubota engine. Basic screed width is 8 feet, with a maximum paving width of 16 feet and max depth of 6 inches. It's 16 feet, 6 inches long with a transport width of 8 feet, 6 inches. Operating weight with the smallest screed is 18,200 pounds. Hopper capacity is 7 tons. The PF161C has the same maximum widths and depth. It weighs in at 27,500 pounds and has a hopper capacity of 9.8 tons. Maximum paving speed is 196 feet per minute, and maximum travel speed is 9.9 mph. Mauldin The Mauldin 1550-D track-type paver has an operating weight, with its small screed, of 12,500 pounds. It has an 8-foot basic screed width with a maximum pav- ing width of 14 feet and maximum depth of 6 inches. Other features include a four-auger material feed system with extending augers, heated screed extensions, Kubota V-3600B 67-horsepower Tier 4 Interim engine, 6.5-ton receiving-hopper capacity and two- speed crawler track driver system. Roadtec Roadtec has both 8-foot and 10-foot pavers, including rubber tire and track machines. The RP-170e wheeled paver has a 174-gross-horsepower Cummins QSB 6.7 Tier 4 engine. It has a mini- mum paving width of 8 feet and maxi- mum paving width of 15 feet, 6 inches. It weighs 29,280 pounds and is 16 feet, 1 inch long. (Weight and dimensions can vary with screen options.)
