What is a CBR? How many CBR tests are required for a pavement design?
For a pavement design, we have to perform several CBR tests as per change in properties of the soil this depends on place to place like from local roads to freeways.
There are many councils on Victoria, Melbourne, Australia, for all of them they have different guideline about how many tests needs to be performed that’s usually based on the geological condition and properties of the soil present on those council areas.
On the basis of importance of roads, how many tests are being done by engineers and their information’s.
How the number of tests varies with the geological condition of the road in Victoria and make a chart to compare these data.
