Butner trap rock has been used in concrete to reach strengths in excess of 15,000 psi. This type of high strength concrete is often used in massive, high use building structures such as commercial parking decks. Trap rock is also naturally fire resistant, with a measured melting point of about 1450° C.
Track ballast (usually crushed stone), as it is known, is another important part of railroad infrastructure. Although it may just look like plain ole gravel this stone plays a vital role in acting as a support base for the railroad ties and rails as well as allowing for proper drainage of water away from the rails (which is why the stone is always sloped downward and away from track).
Ballast: Ballast is material like broken stone, gravel or any other granular material spread and packed below and around sleeper.
