Road Base is a crushed blue/grey rock ranging in 20mm in size down to dust. The smaller rocks and dust help to compact the Road Base down hard to give you a firm stable surface to work with. Our Road Base is CBR 45 which stands for the ‘California Bearing Ratio’ and refers to the strength of the rock itself. This grade is extensively used by road builders around Ipswich and Brisbane. When compacted properly, 100mm of road base can compact down to 80-75mm. For the best compaction make sure the material is wet, this makes sure the fines combine tightly with the larger stones.
