Crushed Stone - an overview ScienceDirect Topics

Traditionally, base course aggregate mixtures have been designed using larger aggregate size than surface course aggregate mixtures—the maximum aggregate size had tended to be in the range 0.75–1.5 inches (19–37.5 mm) which helps to produce a lean mixture with low asphalt binder content thereby reducing the cost of such mixtures but this must not be at the expense of efficiency. More recently,
