A cubic yard is a measure of volume, yet you are trying to convert it to a tonne, which is a measure of weight. Thus, it is impossible to answer the question entirely correctly; there will always be variables.
The most important variable is the substance. In this case its crushed stone, which is usually an aggregate of otherwise unusable stone, but this material can vary density per batch because of the almost random composition it holds. Some batches could be lighter, some could be heavier. It all depends on the stone varieties involved.
Roughly, one cubic yard will equal approximately 2781 lbs, which is around 1.25 tonnes in the UK and 1.35 tonnes in the US, based on their short tonne measurement. In some cases, with varying density and also added water content, this could be more like 1.5 tonnes up to around 2 tonnes.
To convert pounds (lbs) to cubic feet, you divide the weight in pounds by 100. 2,000lbs divided by 100 is equivalent to 20 cubic feet. To then convert the cubic feet to cubic yards, you divide the area in feet by 27, giving you approximately 0.74 cubic yards. Therefore, one ton is equivalent to three-quarters of a cubic yard.
