There are several benefits to using crushed rock for your driveway landscaping design. Compared to other types of driveways, such as cement, crushed rock is relatively affordable. It creates a strong barrier to the growth of grass and weeds, and can give the front of your home a polished look. Crushed rock is also durable and will last for several years before needing to be replaced.
Once you have made the decision to install a crushed-rock driveway, there are several design features to consider. One of the most important is the type of rock you will use. Different types of rocks have different colors, textures, and qualities. For example, gravel crushed-rock driveways are usually dark in color, and because of the irregular shape and sharp edges of the rock, these driveways tend to become tightly packed over time, making a smooth surface. River rock, on the other hand, comes in a range of shades from light to dark, and because the stones are worn smooth by water, creates a bumpier surface than gravel.
One interesting material which is becoming increasingly popular for driveway landscaping design is cinder rock, a type of volcanic rock. Cinder rocks are light in color and often irregular in shape, and come in a wide range of sizes. This rock type is popular for driveways because its porous texture and irregular shape make it excellent for drainage; water can't pool on the driveway. It also packs down firmly, resulting in a smooth, sleek surface over time.
Crushed rock is usually sold by the cubic yard -- 27 cubic feet. Once purchased, the rock is typically delivered using a dump truck; then workers (or the homeowner) smooth down the rock over the driveway using special rake-like tools. It's a good idea to hire a driveway contractor to help you decide what type of rock to purchase and to handle the installation.
