While reading a material specification for crushed aggregate, the text mentions both "crushed stone" and "crushed gravel" are acceptable. These materials sound very similar, but they are mentioned individually. I assume that this means that they are not the same. What is the difference? How can I tell the difference if I see them on-site? Example
