I've seen various estimates suggesting that a cubic yard of road crush rock usually weighs between 2500 to 3000 pounds. However, my supplier is indicating that they will only deliver about 2200 pounds. Should I be concerned about this weight difference and request more?

It's true that it depends on the rock type! For example, softer rocks like chalk are lighter than denser ones like granite. It might be worth checking with your gravel supplier or even consulting a geologist to get an accurate density measurement of the specific rock you're buying.
On my project, I figured that one ton of base rock equals roughly 0.75 cubic yards. So, to estimate, a cubic yard should come in at around 2666 pounds. Your supplier’s 2200 pounds sounds a bit low, as per my calculations!
The weight of stone really varies based on its type. Stone from a plant is typically sold by tonnage, while third-party vendors might go by volume and their pricing can be quite different. Just keep in mind that different types of road crush rocks have different weights—something finer will weigh more than coarser materials.
