1 If you are parking heavy trucks or RVs in your driveway, use the larger asphalt aggregate for the bottom 2 inches (5.08 cm) of your layer and the finer aggregate for the top inch (2.54 cm) for a better appearance.  If your subsoil is inferior, new soil will need to be installed before the asphalt paving can continue.
Crocodiles have narrow, pointed jaws with V-shaped snouts. Alligator jaws are more powerful than crocodile jaws and allow them to eat prey with hard shells, while crocodile jaws are designed for a broader range of prey.
Alligator, crocodile, and caiman are all members of the Crocodilian family. However, how they rate in final appearance, durability and usefulness for skins from which to make boots is quite different. Those differences also affect the final pricing of boots made with any of these skins. All skins are graded by quality.
