An introduction to SEDIMENTARY ROCKS. Sedimentary rocks form from sediment. "Sediment" is a general term that indicates loose grains (such as the sand at the beach) and chemical precipitates (such as crystals of salt). Sedimentary rocks can be subdivided in three categories: clastic, chemical, and biochemical sedimentary rocks.

More than 50 percent of the surface rocks in Kentucky are limestones. Limestone is chiefly composed of the mineral calcite (calcium carbonate), but may contain small amounts of clay, silt, chert, and dolomite. Most limestones are layered and contain fossils of shellfish and other animals that lived in shallow seas.
Use a scraper blade to place the rocks along the area and then go over that later with a metal roller pulled behind the equipment to pack the rocks down. Lastly, top the area with number 8 limestone. This crushed limestone is 3/81/2 inch in size. As you place these rocks on top make a crown along the length of the driveway, higher than the sides.
