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-
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

. The SprayJet nozzles do not
spray the emulsion continuously, but oper-
ate instead in pulsed mode.
