Igneous rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. Igneous rocks are divided into two groups, intrusive or extrusive, depending upon where the molten rock solidifies.
Crushed brick is one of the major components of demolition materials.

The crushed rock should be spread to a depth necessary to meet the desired compacted crushed rock thickness. (For example, spread 7″ to 8″ deep to get a 5″ compacted depth) After initial smoothing and compacting, the edges are back-filled and dressed smooth. Finally, the trail surface is re-compacted with rollers or vibratory compactors.
