The MA30 applies frictional mastic surface treatment (FMST) over asphalt pavement. The patent-pending, variable-width, low-pressure spray bar has side-shift capabilities. FMST is a mixture of asphalt emulsion, angular fine aggregates, recycled materials, polymers and catalysts and is used to minimize future maintenance treatments, the company says. The material mix is made to specification and held in a steel 3,000-gallon tank, which contains a hydraulically driven, full-sweep ribbon mixer with counterflow mixing technology. The driver can control the system from the cab, including 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.

The MA30 offers a technologically advanced low-pressure system that operates at less than 40 psi. It offers single- or dual-pump operation, with more than 100 gpm delivered through the spray bar in single-pump mode and more than 200 gpm 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 72-in to 234-in, in 18-in increments.
