Voids, settlement and weight of crushed stone,

Crushed stone has become an important material of construc-tion in modern engineering work. The chief causes for this are the great increase in the use of plain and reinforced concrete, and the increased activity in macadam road construction. The advances made in these lines have been so rapid that crushed stone has suddenly changed from a minor material to one of first importance in modern
