If you are building a country road Ginninderra Road Gravel is an excellent product for the job. It is a cost effective product, as it is sold at a reduced price to the main line as it is not screened and therefore does not have the same even consistency as the Ginninderra Red Granite product. The Road Gravel needs to be rolled to get an even surface and once it has been wet and rolled you have a permanent all weather earthy red road that resists erosion. This has been a very popular product for country roads around Goulburn, Yass and the Southern Highlands.
The Ginninderra Red Granite has an earthy red colour, when it is first quarried or viewed as a sample it does not appear red but after it has been wet, it oxides and a lovely red colour appears. The granite structure insures excellent compaction with an average CBR Value of 60, the plasticity index is 10% and it has a swell rate of 0.0%. (See the latest grading on this site.) The Ginninderra Red porphyry decomposed rock composition makes it unique enabling it to have excellent compaction forming a permanent surface that resists erosion. It meets the ACT and NSW wearing course specifications as specified in the ARRB group pavement and materials design manual.
