  • Sand and Gravel - Products | Lehigh Hanson, Inc.

    Erosion and weathering render the stone round instead of angular. This shape is the principle difference between crushed stone and sand and gravel. About 44% of construction sand and gravel is used as concrete aggregates, 25% for road base, and 13% as aggregate for asphalt. The remainder is used for base, fill and other applications.
