Super 1800-2 SprayJet

The Super 1800-2 SprayJet paver from Vögele America Inc. is designed for pavement preservation surfacings like NovaChip® Ultrathin bonded wearing courses. The Super 1800-2 SprayJet permits spraying of a tack coat and asphalt paving to take place in one pass, promoting optimum bonding between layers, keeping the jobsite clean, and eliminating the tack coat truck from the paving train. As only minor modifications are needed for operation with the module, the paver also can be used for conventional paving when the SprayJet module is removed. Without the SprayJet module the Super 1800-2 can pave up to 32 feet 10 inches wide, with a laydown rate of up to 772 tons per hour and forward speed of up to 79 fpm. But the Super 1800-2's ability to spray liquid asphalt or emulsion also makes it an ideal application vehicle for ultrathin bonded wearing courses, in which modified emulsion and aggregate can be placed in one pass. Five precisely adjustable spray bars with a total of 20 self-sealing spray nozzles are located at the front, sides and behind the crawler tracks, and are supplied with emulsion from a large, heated tank with a capacity of over 528 gallons. The SprayJet module incorporates a high-precision control system which lets it spread emulsion in small volumes (from 0.04 lbs./sq. ft.) at slow pave speeds. Its very low constant spraying pressure (43.6 psi) lets spraying be undertaken with very little mist and drift. And without the SprayJet module, the Super 1800-2 SJ reverts to a conventional high-performance paver. With Vögele's ErgoPlus design, operation of the SprayJet module is simple. Once the operator has set the required quantity to be metered, the spray pressure and spray rate are automatically adapted to the paving speed and width. The Super 1800-2 SprayJet uses the ultra-modern AB 500-2 Extending Screed, which permits paving widths of up to 16.4 feet wide. Featuring electric heating, the screed and emulsion tank are heated independently, so heating of the emulsion can take place without having to heat the screed. An additional gas heating system can be used to quickly heat up cold emulsion.
