SprayJet technology from VÖGELE has been proving its value for many years and is used for pavement rehabilitation and construction in many markets around the world. The new SprayJet features a large array of impressive innovations. One key feature is that operation of the spray module has been integrated into the ErgoPlus 3 operating concept. The module is designed as a completely self-contained functional unit. This modular design makes the new SUPER 1800-3i SprayJet simple to service and allows it to be used both as a spray paver and as a conventional asphalt paver. The paver has a maximum spray width of 6 m. As a conventional paver without spray function it can pave widths of up to 9 m.
Application areas for the SUPER 1800-3i SprayJet
Rehabilitating roads by replacing the surface course is a highly cost-effective and eco-friendly process, and very popular in numerous countries. VÖGELE now presents a cutting-edge concept that is not only ideal for paving thin layers of hot-on spray seal or tack coat but also highly interesting for many non-specialized road building companies. The newly developed VÖGELE SprayJet module is an economical and clean alternative wherever emulsion is sprayed before paving with asphalt.
The VÖGELE SprayJet module
The new spray module features several innovations. The insulated emulsion tank, for instance, now has a capacity of 2,100 l. The capacity can even be increased to 7,100 l with an optional additional emulsion tank. The integrated electric heating (2 x 7 kW) ensures that the emulsion is reliably maintained at the ideal temperature for spraying. What's more, a heated emulsion pump circulates the bitumen emulsion in the tank, thus ensuring that it is permanently homogenized. A new additional filler port on the left-hand side of the "Dash 3" spray module makes for greater flexibility when refilling. And last but not least, all the main service points are readily accessible behind large service panels, even with the spray module installed – much to the delight of every user.
Clean and Safe Spraying Process
The SUPER 1800-3i SprayJet is equipped with five spray bars. The front spray bar has six spray nozzles and is located between the machine's crawler tracks right behind the push-rollers. An articulated spray bar installed on each side of the paver comes with seven nozzles per side. Finally, a short spray bar with two nozzles is provided right behind each crawler track. This arrangement of the spray bars allows full coverage of the existing surface with emulsion, even when the pave width varies. The rate of spread can be selected accurately within the range of 0.3 and 1.6 kg/m². The SprayJet nozzles do not spray the emulsion continuously, but operate instead in pulsed mode. The frequency of the spray pulses is adjusted automatically as a function of the selected rate of spread, pave speed and pave width. As a result, the existing surface can be completely covered with a uniform film of emulsion, without any overlaps. Emulsion is applied at an exceedingly low spray pressure of no more than 3 bar. In combination with the high-quality spray nozzles, this allows the emulsion to be sprayed cleanly and without harming the environment.
"Dash 3" features also available with the SUPER 1800-3i SprayJet
It goes without saying that the new spray paver also includes all the features of the "Dash 3" paver generation. The VÖGELE EcoPlus package, for instance, significantly reduces both fuel consumption and noise levels. The AutoSet Plus functions ensure quick and safe relocation of the paver on site and make it possible to store individual, frequently recurring paving programs. Even the best machine with the most advanced technology can only really show its strengths if it can be operated easily and as intuitively as possible. At the same time, it must offer its users a safe and ergonomic workplace. That is why the new ErgoPlus 3 operating concept focuses on the operator and user-friendliness.
The paver operator's ErgoPlus 3 console
Like all "Dash 3" generation pavers, the SUPER 1800-3i SprayJet comes with the VÖGELE ErgoPlus 3 operating system which substantially facilitates the paver's handling. Important spraying functions have been integrated into the large color display on the paver operator's console, which offers outstanding legibility even in poor lighting conditions. The maximum possible pave speed is displayed here for the paver operator as a function of the set rate of spread. In addition, the handy automatic functions "Start of Job" and "End of Job" can be activated at the push of a button. Spraying begins and ends at precisely the desired point and is reliably executed over the full spray width.
The ErgoPlus 3 screed console
The safe and easy handling of all screed functions is vital to high-quality road construction. All the essential data are displayed on the two ErgoPlus 3 screed consoles. Self-explanatory symbols make it easy to set or adjust parameters for the screed, conveyors and augers or grade and slope control. Hydraulic adjustment of the crown, for example, can now be carried out very conveniently via the ErgoPlus 3 screed consoles. The VÖGELE SmartWheel is another exceedingly useful new feature. With it, the pave and spray width can be set in two speeds: slow, for precise screed width control along an edge, or fast, for rapid extension or retraction of the screed. The two outer nozzles on the lateral spray bars can be activated and deactivated to obtain an accurate sprayed edge.
The ErgoPlus 3 control panel for the SprayJet module
Operation of the SprayJet module has been consistently integrated into the ErgoPlus 3 operating concept. This applies not only for the icons used on the operator interface, but also for the functional principle of "Touch and Work." All functions for preparation, spraying and cleaning are conveniently selected and started via the touchscreen. Work sequences are set automatically in accordance with the function which has been selected and started. Depending on the installed nozzle size and the selected rate of spread, the maximum pave speed is calculated by the SprayJet module's control unit and displayed on the ErgoPlus 3 paver operator's console. This ensures uniform application of the emulsion. The rate of spread can be set here just as easily and the nozzles calibrated or switched on and off individually. Correct operation of the front spray bar is monitored electronically, as it is out of sight of the screed operator. In addition, lines and valves are cleaned in a fully automated process controlled by a separate program. All this makes operation of the SUPER 1800-3i SprayJet extremely safe and simple.
VÖGELE extending screeds for perfect pavement quality
For the SUPER 1800-3i SprayJet, two screed options are available: AB 500 and AB 600. Either of the extending screeds handles pave widths up to 6 m. AB 600 comes with a basic width of 3 m and extends hydraulically up to 6 m. AB 500 builds up to its maximum width of 6 m with additional bolt-on extensions (75 cm). The widths of the screeds are limited electronically to a maximum of 6 m. As a conventional paver without spray function it can pave widths of up to 9 m with the AB 600.
Either screed is available in TV version (with tamper and vibrators) or in TP1 version (with tamper and one pressure bar). Like all VÖGELE screeds, the AB 500 and AB 600 Extending Screeds also feature electric heating.
