Road RippingRipping

The ripping up of the existing track allows the whole track up to a depth of 300mm to be completely rebound.

The trouble with putting a new surface on top of an old one, ie. a new layer of gravel is that only the introduced material will bind.  With only the top layer binding it is only a matter of time before water will run off, frost and with general use that the pot holes return and the track deteriorates.

By using the ripper the track is effectively rotavated to up to a depth of 300mm and will also produce larger pieces of material large rock etc that can be crushed down to provide surface material or more effective base material.

Stone CrusherStone Crusher

The crusher works by a rotor with fixed tungsten carbide hammers mounted on a drum that crushes the stone against an adjustable anvil.

While this provides uniformity within the crushed material the adjustable anvil means that you have control over the size of the stone so as to have the bigger stone for your base material providing strong foundations.  Middle sized stone for the centre and fines from the bottom to the top surface layer to provide the all important binding material. Again it is the all important binding of the material that both the ripper and crusher produce that makes this such an effective way to maintain the track.

Road GradingThe Grader

Once you have ripped and crushed the track you should now have a strong base layer, middle and top bound together by the all important fines. At this stage it’s most important to try provide some form of camber to shed any water.

The grader shapes the surface of the road to either follow any natural slope of the surrounding ground or into ditches and drains on either side of the track.

Having been levelled the track will be ready to be rolled and sealed, compaction providing that final hard surface.
