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.

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.
Size. There are two different types of alligator, and they vary in size. The American alligator can grow up to 11.2 feet (3.4 meters) long and weight nearly half a ton (1,000 lbs. or 454 kilograms), according to the Smithsonian National Zoological Park.Chinese alligators are smaller, growing to around 4.6 to 4.9 feet (1.4 to 1.5 m) long and usually weighing only around 50 lbs.(22.7 kg).lligators are large reptiles, members of the order Crocodylia. Alligators and crocodiles are, therefore, closely related, and people often confuse one with the other; however, these two reptiles are very different. An alligator is distinguished by its wide, rounded snout and black color.
