The question about the particle density of graded crushed stones is a bit complicated. Since it is a gradation, it depends on whether it is artificial or natural gradation. If it is artificial grading, it depends on what region and what mineral structure aggregate. And then look at the gradation composed of several material diameter ranges (how much porosity.
