All of our Roadbase products are made from rock or concrete sized 20mm and under. These products are used for driveways, hard stand areas, footpaths, building pads & bases for laying asphalt.
Bitumen Scalps is the top layer of bitumen from roads that have been dug up from road works. It is an unscreened product that contains mostly bitumen with very minimal roadbase. It is mostly 20mm & under but does contain some larger chunks of bitumen that haven't been broken up.
The Recycled CBR15 is the cheapest of the road bases. It is made from crushed concrete, brick, asphalt & soil and is used predominantly as a screened compactable fill.
We also have a Natural Rock CBR15 which has a clay like base that binds quite well, great for hard stand areas or driveways on a budget. The colour of the natural rock will vary but is usually brown or orange.
Our CBR45 (MRD2.3) & CBR80 (MRD2.1) are our top of the line roadbases, made from blue metal natural rock. They're the best options for driveways as they have the best compaction ratios, binds well, will hold up the best under traffic & avoid erosion.
The ratio to convert tonnage to cubic meters for road base products is roughly 2 tonne equals 1 cubic metre. For example, a full 13 tonne truck load of road base will cover around 6 to 7 cubic metres after compaction.
The abbreviations CBR (California Bearing Ratio) or MRD (Main Roads Department) stand for common compaction tests. They do not refer to the size of the rocks - all of our road bases are made from rocks sized 20mm & smaller.
