Whilst still a prototype, this unique machine – and looking remarkably similar to the K190 bush hammering unit - is based on the well-known diamond grinding principle but with significant differences. MGT has been the subject of major technological design and development and is a considerable improvement on current grinding systems, the technique being able to deal with wheel-tracked or rutted surfaces.This machine is designed specifically to restore skid resistance and/or reduce noise (particularly on concrete surfaces) on any road and runway surface.

Accurate control and because of the unique way the cutting drums are mounted means that it is possible to apply a consistent and even treatment to uneven surfaces over the full retextured width. Adjusting the drum rotation speed, the downward pressure of the cutting drums and the working speed, ensures the MGT machine can be used on any natural aggregate surface course (bituminous as well as cementitious) in order to restore micro texture and, where required, macro texture. These adjustments can also accommodate different surface bitumen conditions, aggregate sizes and the degree of accelerated weathering.

This process is particularly suitable for surfaces that can’t be treated with impact-based processes. The MGT machine is now ready for final testing to fine-tune the system. This will determine the operational parameters to achieve the optimal result of micro (and/or macro) texture improvement on different road and runway surfaces.

- Improve surface friction, skid resistance and provide mechanical key for material overlays, by:

- Restoring micro texture
- Restoring macro texture (on some surface types)

- Reduce noise
