Track rock dressing grade

Important Information

• BENEFITS

  Dressing Grade Track Rock has cementing properties under compaction, such as Track Rock but is designed to be used as a maintenance layer over top of an existing formed track. Dressing Grade Track Rock can be laid over a rotten rock base course to give the added benefits of Lime, such as a smooth stable race and gentle to the hooves of animals.

• USES

  Dressing Grade Track Rock is used principally for the maintenance (topping up) of tracks and races. Its major use is currently in reconditioning dairy tracks. Other uses include all weather airstrips, stand-off / feed pads and jobs that require a smaller chip on top for a smoother race or track.

• APPLICATION

  As Track Rock dressing grade is finer than normal track rock it will perform best if it laid at an even spread of generally 50-100mm. Any pot holes, muddy areas and dips will need to be scraped back to base and built up with suitable sized product like 65mm Track rock. This will allow the even spread of Dressing grade layer to be formed up into a crown and suitable compacted. Filling wet spots and muddy potholes is not recommended for this product.
  
  Ravensdown stands by its products and has literally thousands of meters of excellent performing farm tracks, up and down the country. However, because Ravensdown has no control over; the base the track is laid on, the application of the Dressing Grade Track rock and the finishing of the track, Ravensdown cannot be held accountable for any issues regarding the track’s performance. Contact your local quarry for suitable contractors near you.

• STORAGE

  Does not need covering in the stock pile.

• SOURCE

  Ravensdown has no “specified standard” Dressing Grade track rock at our quarries and as such you will find different Dressing Grade track rock products offered as you go from site to site. Sizing can vary as can the grading but in general the following descriptions are appropriate for the site in question. If in doubt please make an appointment to visit your local quarry to inspect the Dressing Grade Track Rock yourself, or, phone either your local Quarry manager or the Customer Centre.
