Chipped stone is most commonly used for driveway applications. Our standard chipped is a michigan field stone crushed rock washed and screened to size. Our limestone is trucked from south of us near the ohio border to get the "harder" rock that creates less breakdown. The slag is becoming more popular and is also an angular material screened to size that is a bi-product of steel. We also have a couple gravel blends with fine material mixed in with stone to serve as a solid base that packs great for projects such as driveways or patios. All of the angular stone work great for driveway applications but can also be aesthetically pleasing in an area for landscape that doesn't have foot traffic. The chipped michigan stone actually provides a slightly more vibrant color due to the broken inside surfaces being exposed!
