Super 1800-2 SJ paves way to more efficient road repairs

For repairing roadways quickly, the Vögele Super 1800-2 SJ cuts down on time and mess with a built-in sprayer system.

Vögele, a German-based company, has looked to the future for a new product to meet the needs of not only the European market but also many other parts of the world. As a result, it has introduced the Super 1800-2 SJ (SprayJet) paver.

With the current economic climate causing both governments and contractors to look for ways to cut costs, emphasis is being placed on the upkeep and reconstruction of existing roads, instead of the building of new ones. The Super 1800-2 SJ has been introduced to fill this anticipated need. It is able to spray sealant over old road surfaces and then pave a thin overlay of asphalt, all in one pass. Where spray is not needed, the paver can be used in conventional road-building methods. Its ability to spray liquid asphalt or emulsion allows for paving of very thin roadways of emulsion and aggregate.

The inclusion of a sealant or tack coat into the paver removes a spray truck from a paving fleet, cuts down on mist being released into the environment, and eliminates the mess caused by other vehicles that drive over wet coats and then mark other roads.

The Super 1800-2 SJ is powered by a Perkins inline six-cylinder turbocharged diesel producing 174 hp (130 kW) and powering hydraulic crawler tracks.

The SprayJet tank holds 528.4 gal (2000 L) of sealant or emulsion, continuously pumped, heated, and monitored by the onboard control system. Temperature settings and spray volume can be adjusted, regardless of paving speeds, and any of the 20 nozzles can be individually turned off if necessary. An optional tank can add another 1321 gal (5000 L) of sealant for long, thick sprays, and two pairs of sprayer extensions can be added to total 19.7 ft (6 m) of spraying and paving width.

The SprayJet module reduces the paving width from the maximum of 32.8 ft (10 m) on the standard Super 1800; however, this width can be achieved by removing the SprayJet module, leaving a traditional paver capable of 79 ft/min (24 m/min) and 772 ton/h (700 t/h).
