The TURBO uses a specialised spray-injection technology for cleaning and filling potholes in road surfaces with a cold aggregate mixture. The method involves the continuous formation of a mixture of aggregate and asphalt emulsion directly above the pothole, ensuring efficient and long-lasting surface repairs.

Principle of the technology:

1. Cleaning the pothole – A powerful stream of air removes debris and prepares the surface for repair.
2. Priming the pothole – Asphalt emulsion is introduced into the air stream, penetrating the pothole.
3. Filling the pothole – Aggregate is drawn into the air stream and coated with emulsion before impact. The air stream forces the aggregate into the pothole, gradually filling it.
4. Final finishing – Application of clean aggregate seals and strengthening the repaired pothole.

 The spray patching unit is mounted on a single-axle trailer. The trailer carries the complete technology, including an insulated emulsion tank, a powerful blower and an easy-to-operate working arm. TURBO is a reliable tool for road maintenance. All functions can be conveniently controlled directly from the working position at the pothole.

At the front of the trailer there is a small aggregate hopper with a screw conveyor, which is continuously supplied from the truck bed of the towing vehicle. A winter road spreader can also be used as the aggregate hopper, allowing it to be utilised together with the towed patching unit during the summer season.
