Bergkamp releases MAXX applicators
By Andrew Macklin
February 2, 2016 – Bergkamp Inc. offers the MAXX line of truck-mounted Frictional Mastic Surface Treatment Applicators, which allow contractors and government agencies to apply premixed frictional mastic surface treatments and premixed slurry seal over highways, roads, parking lots and airport runways.
Frictional mastic surface treatment is a mixture of asphalt emulsion, increased levels of angular ﬁne aggregates, recycled materials, polymers and catalysts. The purpose of the treatment is to protect the pavement surface and extend its life, while minimizing future maintenance treatments. It is designed to allow trafﬁc back on the pavement faster following treatment than with other processes.
Available in two models, the MA20 and MA30, the MAXX Applicator applies a material mix that is made to precise specification, resulting in fewer operator calculations and on-the-job adjustments, which minimizes operator training time.
The full-length ribbon mixer works to maintain the proper material consistency during transit, pumping and spraying operations, regardless of the truck engine speed. The pavement treatment is then applied over the existing pavement through a patent-pending, hydraulically operated, variable-width, low-pressure spray bar that has side-shift capabilities. Hydraulically powered pumps automatically adjust to the truck’s speed, ensuring accurate application rates at variable speeds.
The MA20 has a 7,571-litre material tank and the MA30 features an 11,356-litre material tank. In either model, this steel tank contains a hydraulically driven, full-sweep ribbon mixer with counterflow mixing technology that keeps the aggregates in suspension. In-cab controls eliminate the need for a rear operator by allowing the driver to operate all systems, including the mixer start/stop/reverse and spray bar start/stop, height and width, side-shift and individual nozzle controls. Application is computer controlled with an onboard system that ensures accurate application rates by continuously varying the pump rate, based on the truck speed and spray width. Easy-access mastic strainers protect the pump and spray nozzles from clogging and potential damage by aggregates and solid material.
The MAXX line offers a technologically advanced low-pressure system that operates at less than 40 psi (275.8 kPa). It provides single- or dual-pump operation, with more than 100 GPM (378.5 L/min) delivered through the spray bar in single-pump mode and over 200 GPM (757 L/min) delivered in dual-pump mode. In dual-pump operation, the product loads in less than 30 minutes. All systems are powered by PTO-driven hydraulic pumps. The hydraulically adjustable spray bar provides double overlap spray widths from 18 inches to 234 inches (0.46 m to 5.9 m), in 18-inch (457 mm) increments.
