The RA-400’s VORTEC (Vacuum Operated Rock Transfer Emulsion Coating) system uses air to shuttle material from the hopper through the boom assembly. Delivering the air, aggregate and emulsion needed in the spray patching process is a low pressure (3-4 PSI) system that keeps material flowing into the air stream and eliminates the need for moving parts.

A five-yard aggregate hopper and 300-gallon emulsion tank lets the RA-400 patch for days, requiring only occasional aggregate fills. Daily maintenance is minimal. Rosco’s three-way valve smoothly changes from clean out to operation and the few wearing parts are easily accessible. At the end of the day clean out takes only seconds and the RA-400 is ready for the next job.

One person controls all patching functions from the safety and comfort of the RA-400’s cab. The industry leading hydraulic Patch-on-the-Go system allows for patching on the move utilizing a Kubota Tier 4, quiet running, fuel efficient, auxiliary engine.

Patching with the RA-400 spray injection process lets the operator repair large numbers of problem areas in a single day. The driver operates a joystick from the driver’s seat and performs the four-step process, typically in less than a minute per repair.

During the patching process the patching boom extends and retracts while on the move with the operator’s joystick controlling boom movement. The patented 3-stage telescoping aggregate delivery tube and emulsion hose take-up reel provides a wide patching range with minimal maintenance.

With the operator safely protected in the vehicle and with the rear arrow board to direct traffic movement, work may continue in low traffic or high traffic areas.

Best In Class

The RA-400’s right-hand joystick controls all functions including material flow and boom movement. This one person operating systemis both efficient and safe.

All patching functions are conducted from the vehicle, protecting the operator from risk and the elements.The spray injection patching process can be performed in temperatures above 0o F. The hopper vibrator prevents bridging of aggregate, common to other spray injection systems.

The pothole is cleaned with a high-volume blower.

A tack coat of emulsion is applied to the area.

A mixture of aggregate and hot emulsion fills the pothole.

A finish coat of dry aggregate and traffic flows!

Spray injection with the RA-400 is easy and effective. According to the National Research Council’s SHRP Report, spray injection patching is the most economical and longest lasting method of pothole repair.
