Asphalt roller 3 ton

Types of asphalt roller 3 tons

An asphalt roller 3 ton, also known as a compactor or road roller, is a heavy construction machine used mainly for compressing or leveling various asphalt materials. There are now many types of asphalt rollers based on different criteria.

• Divided by vibration sources

  Whether the electricity generated by the power grid or the vibrations produced by the engine internally, hydraulic or mechanical systems can transport them to the drum and then to the ground. Diesel rollers have a higher adoption rate than electricity-powered ones. However, the latter may be preferred in places where emissions are a significant concern, such as urban environments and national parks.

• Divided by vibration types

  Dynamic and isotopic vibrations are two forms of vibrations produced by asphalt rollers. While the dynamic vibration roller comprises a vibrating motor that transmits vertical shocks throughout the entire drum, the isotopic vibration roller utilizes eccentric weights to create shocks that are not just vertical but also horizontal.

• Divided by the number of vibrating drums

  Seven types of rollers are usually identified by one or two vibrating drums. The single vibrating drum roller comprises a vibrating drum at its front, while the rear roller has a vibrating drum at its back. On the other hand, double vibrating drum rollers have two vibrating drums, with one at the front and the other at the back.

• Divided by mechanisms

  Asphalt rollers are usually divided into two main categories based on the mechanism that produces vibration for compaction: static and dynamic. Static rollers rely solely on their weight to achieve ground compaction. On the other hand, dynamic asphalt rollers produce vibrations through eccentric shafts or motors, resulting in a splitting force that further aids in ground compaction.

Every asphalt roller serves a specific purpose and has its own advantages.

Specification and Maintenance

The specifications of an asphalt roller vary depending on the design and function of the machines. However, here are some standard specifications for most rollers.

• Weight and Size: The weight and size of the asphalt roller affect its compaction force. Smaller rollers could weigh about a ton and be used for surface compaction of around 70 inches. Bigger rollers can weigh as much as 12 tons or more. The dimensions of these machines usually depend on the design and function of the roller.
• Operating: Smaller asphalt rollers with 3-ton averages have an operating speed of 5 km/h. Some larger rollers can have an operating speed of 10 km/h, making them a bit faster than smaller options. The speed of the machine affects the quality of the pavement.
• Way: Asphalt rollers are designed to move on paved surfaces. Some have steel tracks or rubber tires that help them work efficiently on different paved surfaces. Other designs include oscillated rollers that combine steel tracks with drums.
• Wheeled: Pneumatic rollers have multiple wheels that compact asphalt through air-filled tires. These rollers usually have three to five axles with tires across them. The number of wheels and configuration can vary depending on the design.
• Fuel and Power: Smaller asphalt rollers use gasoline and powers of about 10 to 20 HP. Larger rollers use diesel fuel with power ranging from 50 HP to 120 HP.

Maintenance

Proper maintenance of asphalt rollers helps ensure that they provide better paving work and before-delivery services. Here are some parts of the machine that require regular maintenance.

• Daily Check: Operators of the roller should inspect the whole machine to notice any part that may need repair. They should fix damaged parts before using the asphalt roller on paved roads. Regularly checking the machine helps avoid accidents that can occur from operating a faulty roller.
• Fluid Levels: While doing daily checks, operators should check the fluid levels of the roller. They should ensure the diesel and hydraulic fluids are at the right levels. If they notice low levels of any liquids, they should top them up to avoid mechanical failures during operation.
• Parts Cleaning: Some parts of the asphalt roller, like drums, tracks, and tires, collect loose material while paving roads. If not cleaned, these materials can harden or damage the roller part. Moreover, debris can affect the quality of the paved road. Therefore, cleaning these parts is essential for maintaining the roller's quality.
• Lubricate: There are parts of the asphalt roller that need to be lubricated regularly. These include the bearings, chains, and track drives. Lubricating these moving parts prevents wear and tear and ensures smooth and efficient movement of the machine.

Application Scenarios of Asphalt Rollers

Asphalt rollers, sometimes called asphalt compactors, are critical pieces of machinery in the road and pavement construction industry. They provide a smooth and even surface for roads, driveways, parking lots, and more by compacting the asphalt mixture once it is laid down. Here are some major application scenarios where side and rear rollers are extensively used:

• Building and Urban Infrastructure: Asphalt rollers are widely used by construction companies to lay down asphalt for roads, streets, and pathways in urban areas. They are especially critical in building urban infrastructure, including roads connecting huge residential areas. The 3-ton asphalt roller is the perfect size for compacting asphalt in smaller projects and urban spaces where maneuverability is crucial.
• Rural and Urban Road Paving: Both rural and urban road paving requires asphalt rollers to lay the roads that connect to farmlands. The machines help create durable roads that make it easier to access farmlands.
• Airport Runway Construction and Maintenance: It's vital to have correctly compacted asphalt with no empty spaces for the runways of planes at the airport. The compacted area has to be strong enough to withstand the heavy plane traffic. Therefore, big asphalt rollers with a lot of weight are often used.
• Layering of Highways: Big asphalt rollers with a heavy weight are often used to pave highways. The highways need many layers of asphalt because many cars drive on them. Heavy asphalt rollers can easily compact the thick layers.
• Extension Projects: When the thickness of the existing pavement requires compaction, extension projects of this nature necessitate the use of heavy-duty asphalt rollers.
• Soil Stabilization: The soil on which a pavement is to be constructed must be stable enough to support the pavement. This necessitates the use of asphalt rollers before asphalt is laid on the soil.

How to Choose Asphalt Rollers 3 Ton

It is essential to consider a few things before purchasing an asphalt roller 3 ton. This helps to choose a roller that will meet specific requirements and help the work progress smoothly.

• Understand the requirement of the project:

  Knowing the kind of project will help in choosing the right asphalt roller. If the project is large, a bigger roller like the 12-ton and 18-ton can be used. A smaller roller should be used for working in confined areas. Mix-temperature matters, too. The ground should be well-compacted; hence, a bigger roller should be used.

• Comfort and controls:

  An asphalt roller operator will spend a lot of time in the roller. It is important to choose a roller with well-placed controls and ergonomic seating. Vibration isolation and climate control should also be considered.
