Crushed gravel consists of mechanically crushed stone particles, sand, silt and pebbles, all of which give it an uneven, rough appearance. Pea gravel, on the other hand, consists of small, smooth and round pieces of gravel. Both materials are in wide use for the construction of driveways.
Appearance and Cost
Pea gravel is available in a variety of different colors, such as white, brown and gray. The rocks come in different shapes, like egg, as well as different sizes. Pea gravel tends to be more expensive than crushed gravel, with some decorative options costing about $85 per ton. There are limited choices when it comes to crushed gravel, but it is cheaper with costs ranging around $35 per ton.
Installation and Stability
The installation process for both driveways is somewhat similar, and both need a solid edging to keep the gravel pieces contained. However, crushed gravel settles better and provides more stability than pea gravel. Pea gravel does not provide much stability and shifts around a lot because of the round pieces. With either option, you will have to top up the material from time to time to maintain the correct level and aesthetic beauty.
