Paver machines or pavers are engineering vehicles used for laying concrete or asphalt on a surface. They can be fed through a dump truck and use a roller to press the material, creating a smooth and even surface. For example, an asphalt paving machine is used for laying asphalt. The mix gets loaded into the equipment before being spread out. The asphalt is then laid, leveled, and compacted by a component of the machine known as the screed.
Learn more about the paver machine and how it works.
Asphalt Paving Machines
A look at the functioning of the asphalt paver machine can give you an insight into how a typical paving machine works. Asphalt pavers are self-propelled formless laydown equipment featuring a floating screed. The mix gets loaded in the front and is carried to the rear with the help of flight feeders. Augers spread the mix and the screed levels and compacts it.
Asphalt pavers are designed for the purpose of distributing and compacting layers of asphalt over a surface. Examples of such surfaces include:
- Parking lots
- Roadways
- Walkways
Parts of a Paver Machine
Paver machines are usually self-propelled with tires or tracks. Some are towed with the help of a dump truck. Tracked and wheeled pavers have two main parts, the tractor, and the screed.
The tractor component can have the following parts:
- Hydraulic drives
- Distribution augers
- Receiving hopper
- Engine
- Feeder conveyors
It is the tractor that tows the screed. Some of the parts of the screed include:
- Moldboard
- Endplates
- Vibrators
- Slope sensors
As the machine operates and moves ahead, the feeder conveyors will transfer the mix to the rear. The augers then move out the mix. The width of the augers can be adjusted to match the requirement. As mentioned above, it is the job of the screed to level the layers and compact them.
Size & Power of Paver Machines
Pavers are available in a wide range of sizes and with different power configurations. You can find the right one based on the type of applications you require them for.
- Smaller paver machines that need to be towed can be powered from 3HP to 20HP.
- Bigger models with self-propelled designs can have powers ranging from 100HP to 250HP.
- Large-sized pavers can measure from 19 feet to 23 feet long and weigh up to 40,000 pounds.
- The normal paving width is 8 feet to 12 feet. The maximum width is around 40 feet.
- Wider paving projects can often require screed extensions.
The type of extra equipment and accessories depends on the type of paving job involved. So, these are the equipment and parts commonly required for different types of paving jobs. Whatever mix your project uses, you should expect most paving machines to work on similar principles. Before choosing any paver machine for your business or project, make sure to assess its features and functionalities.
