What’s a road roller?

A road roller is used in road construction to compress and level materials like asphalt, gravel, and dirt. It consists of a roller body with one or more metal drums. The weight of the drum can be increased by adding water. Different models offer various features such as emitting a water-based lubricant or having a vibration system. Road rollers have been around for centuries and were first powered by horses before being replaced by steam power in the 1860s and then diesel in the 1900s.

A road roller is a piece of equipment mainly used in road construction. Causes materials such as asphalt, gravel and dirt to become evenly compressed and level. Typically, a road roller consists of a roller body and at least one metal drum. Sometimes, a road roller may have two or even three drums, depending on the design. In most cases, one person drives the roller, but there are a few basic designs where one person pushes the body of the roller to create a flat surface.

While the steamroller may seem like a modern piece of equipment, it has been around for centuries. Although first used with horse power, horses were eventually replaced with steam power in the 1860s. In the 1900s, the steam roller was replaced by rollers powered by other sources, such as diesel.

Generally, a road roller operates when the weight of the drum attached to the body of the roller causes materials to be compressed and compacted. Drum weight can vary greatly. The drum of a hand-operated road roller may weigh as little as 100 pounds (about 45.4 kg). The hand road roller would not be used to build roads, but is often used for paved walkways or other small projects. Some industrial road rollers, used for road and highway construction, weigh more than 25 short tons (about 22.679 kg).

Typically, the major weight of a road roller comes from the drum which is attached to the body of the roller. The weight of the drum can be increased, in many models, by adding water. The water is heavy, but can be dumped out of the drum when the building project is finished. Thus, due to its low weight, it can be transported more easily.

In many cases, several road rollers may be used for a single construction project. For example, a roller with a single drum and tires may initially be used. Then, once the build area becomes level, a roller with metal drums, rather than pneumatics, can be used to make the build area as compact as possible.

There are many different models of road rollers and each one offers something different. For example, some rollers emit a water-based lubricant. The lubricant works to keep materials like dirt and asphalt from sticking to the drum. Some models have vibration systems that work to make the asphalt or other material even more compact.
