ble behind large service panels, even with the spray module installed. More advanced features 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. A short spray bar with two nozzles is provided right behind each crawler track. The arrangement of the spray bars al- lows full coverage of the existing surface with emulsion, even when the pave width varies. The rate of spread can be select- ed accurately within the range of 0,3 and 1,6 kg/m 2 . The SprayJet nozzles do not spray the emulsion continuously, but oper- ate instead in pulsed mode.

operating concept. The module is designed as a completely self-contained functional unit. The modular design allows the 1800- 3i SprayJet 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 asphalt paver without spray function, it can pave widths of up to 9 m. Rehabilitating roads by replacing the surface course is highly cost-effective and eco-friendly process, and is increasingly becoming popular in many countries, according to Michael Hecker, senior sales manager for southern Europe and Africa at Vögele. “The Vögele 1800-3i SprayJet is a cutting-edge concept that is not only ideal for paving thin layers hot on spray seal or tack coat, but also interesting for many non-specialised road building companies,”

he says. The SprayJet module is said to be an economical and clean alternative wherever emulsion is sprayed before paving with asphalt. The new SprayJet module also comes with several innovations. The insulated emulsion tank, for instance, now has capac- ity of 2 100 ℓ . The capacity can be increased to 7 100 ℓ with an optional additional emul- sion tank. The integrated electric heating (27 kW) ensures that the emulsion is reli- ably maintained at the ideal temperature for spraying. Additionally, a heated emulsion pump circulates the bitumen emulsion in the tank, thus ensuring that it is permanent- ly homogenised. A new additional filler port on the left-hand side of the “Dash 3” spray module makes for greater flexibility when refilling. Designed with uptime in mind, all the main service points are readily accessi-
