Terex shows the Bid-WellŽ 5000 Automatic Roller Concrete Paver
The Bid-WellŽ 5000 Automatic Roller Concrete Paver from Terex Roadbuilding is specifically designed for high performance concrete paving on projects ranging from airport runways, taxiways and aprons to highways. Its innovative dual vibration system quickly consolidates pavements up to 24 in (609.6 mm) thick, delivering a high quality finish. A sturdy truss system design enables the paver to be set up or change widths in a matter of hours, not days, and at one-third the cost of slipform pavers, it's the economical concrete paving alternative. For these reasons, Bid-WellŽ 5000 pavers have been used on more than 100 airport projects worldwide.
The Bid-WellŽ Rota-VibeŽ vibration system delivers superior concrete consolidation of the surface. This exclusive feature facilitates sealing of difficult-to-finish concrete due to harsh mix designs, unpredictable delays, low slump specifications and wind exposure. Rota-VibeŽ delivers up to 5000 vpm (83.3 Hz) over the vibrating roller's 15.5 in (393.7 mm) length to reconsolidate the top 2 in (50.8 mm) of concrete, delivering a denser and more uniformly consolidated concrete surface. Dual 6 ft (1.82 m) long paving rollers help to optimize surface smoothness. The paver carriage features dual chain drive for dependable operation.
Enhancing concrete consolidation, the Bid-WellŽ 5000's dual vibration system mounts to the paving carriage just ahead of the paving augers. Alternately inserted into the concrete as the carriage approaches the paving form, two hydraulic vibrators impart vibration directly to the edge of the concrete slab. Offering frequencies reaching 13,500 VPM (225 Hz), the vibrators' frequency is easily changed at the paving carriage. Vibrator positioning can be adjusted laterally as well as fore and aft during paver set up, while vertical position is quickly adjusted during operation by a hand crank.
The unique truss construction of the 5000 offers quick setup and fast width changes, reducing time at the jobsite. Its 48 in (1,219.2 mm) truss depth and all-welded steel construction deliver the strength to prevent frame deflection at paving widths from 26 to 68 ft (7.9 to 20.7 m). Mounted on 6 in (152.4 mm) legs, the bogies feature four-bogie drive for smooth, accurate frame advancements. A self-propelled, steerable nose wheel assists with onsite movement of the paver.
Operators control the machine and paving carriage from the high-visibility platform mounted on the truss frame or from ground level with the radio remote control unit. This wireless control operates machine up and down movement and auger, Rota-VibeŽ, drums, height and pivot of the paving carriage.
The Bid-WellŽ 5000 comes standard with two lightweight 35 hp (26.2 kW) engines. The first engine powers machine travel and paving carriage movement, while the second is reserved for uninterrupted operation of the paving rollers, Rota-VibeŽ and two augers.
