Types of asphalt milling machines

The asphalt milling machine Wirtgen is a road maintenance and reconstruction equipment, which is used to remove the upper layer of roads made of asphalt. Different types and sizes of asphalt milling machines are available to suit different projects and circumstances.

• Large-scale cold planers: Large-scale cold planers are also known as big asphalt milling machines. They are widely used for various large-scale asphalt road milling projects such as highways, major urban roads, and airport runways. Equipped with high-power diesel engines, they can achieve high removal rates. Their working width can reach 1 meter or more, depending on the model. One feature of the large-scale cold planers is that they usually have a load-out conveyor system, which can directly conveyor the milled asphalt into the trucks.
• Mid-size cold planers: Mid-size cold planers are sometimes referred to as standard asphalt milling machines. They are smaller versions of large cold planers, but they are still considered the main asphalt milling machines. With more versatility, they are suitable for dealing with urban roads, local roads, and various road reconstructing projects. The working width of mid-size cold planers is typically between 0.5 meters and 1 meter. Their features are similar to those of large-scale cold planers, and some models are also equipped with a conveyor system.
• Small cold planers: Small cold planers are also known as countertop asphalt milling machines or road reclaimers. They excel at precision milling and are ideal for working in confined spaces or tight quarters. They are the most versatile and maneuverable asphalt milling machines among all types. Their working width is around 0.3 meters to 0.6 meters. Furthermore, many models feature a tool spacing that can be adjusted to achieve milled surface depths of up to 50 millimeters.
• Fixed-width and high lead asphalt profilers: Unlike the above milling machines, which use drums with rotating knives to shred material, fixed-width asphalt profilers are pushers that provide a fixed width of asphalt to be cleaned in a single pass. They are ideal for projects with limited traffic disruption requirements. On the other hand, high lead milling machines feature a unique design with a lead axle positioned in front of the cutter head. They excel in increasing pavement smoothness and reducing the need for additional passes.

Specifications and Maintenance of Asphalt Milling Machines Wirtgen

The key specifications for the asphalt milling machine Wirtgen are based on the type of equipment. These specifications can differ depending on the model and may include the size/width, engine power, cutting depth and width, and transportation features.

It is important to note that regular maintenance is crucial to the performance, efficiency, and safety of the asphalt milling machines. Operators and owners should follow the manufacturer's maintenance schedule and recommendations to avoid any downtime or equipment failure. Some of the regular maintenance practices may include the following:

• Regular engine maintenance: This includes oil changes, air filter replacements, and inspections for signs of wear or damage.
• Hydraulic system maintenance: The operator should read and understand the manufacturer's guidelines to know the recommended hydraulic fluid and filter changes. Regular inspections should be done to identify any leaks or damaged hoses or components.
• Cutter components maintenance: The cutter heads and blades should be inspected regularly and replaced or repaired to ensure the machine maintains optimal cutting performance.
• Tracks and undercarriage components: These parts of the milling machine should be cleaned regularly from any asphalt or debris build-up and inspected for signs of wear or damage. They should also be lubricated regularly as per manufacturer guidelines.
• Electrical system and components: The connections, sensors, and wiring should be inspected regularly. The operator should ensure no exposed wires or corroded connectors. The battery should be checked to make sure it is securely mounted, clean, and free from corrosion.
• Cab and operator controls: The operator cab components should be cleaned and checked for any signs of wear. All controls should be functioning properly, and any issues should be addressed immediately to ensure operator safety.

Application scenarios of asphalt milling machines

• Pavement removal:

  The primary use of asphalt milling machines is to remove existing pavement layers. It can be used for full-depth excavation of the entire pavement structure or partial removal of surface layers.

• Surface rehabilitation:

  Asphalt milling machines can also be used and cured to improve the road surface before repaving. The machine can also level irregularities and make the surface more uniform and smooth to enhance the quality of subsequent repavement layers.

• Crown restoration:

  Asphalt milling machines can help restore the road crown. The crown refers to the natural arch-shaped profile of the road, which facilitates water drainage. This natural profile may be destroyed by the unevenness of the road due to wear and tear or by the addition of new pavement layers. Restoring the crown is vital to maintaining proper drainage and preventing water from pooling on the road, which could accelerate deterioration.

• Edge milling:

  The edges of the road are usually severely damaged, mainly because of the constant use of the road by vehicles moving off and onto it. Asphalt milling machines can correctly treat the road edges, which improves the overall road quality and eliminates the need for further repair at the edges.

• Transitional construction:

  Milling can be extensively used where there is a need to connect newly paved sections to existing roads. This includes areas where there are intersections, transitional areas between different road types, or places where new roads connect to existing road networks. The asphalt milling machine helps create a smooth transition between roads, improving traffic flow and safety.

• Bridge approaches:

  Bridge approaches are areas connecting the bridge to the regular road. The height difference between the bridge and the road may cause an inconvenient and unsafe situation. Asphalt milling machines can assist in bridging the gap, thus improving safety and convenience.

Asphalt milling machine Wirtgen Q & A

Q1: What is the difference between micro milling and normal asphalt milling?

A1: While both processes aim to improve the road surface, they do so to different extents. Normal or full-depth milling removes 1 inch or more of the road surface, while micro milling typically removes only 0.12 to 0.5 inches of material. Micro milling can also produce a much smoother surface than standard asphalt milling.

Q2: How has asphalt milling technology improved over the years?

A2: Recent developments have made the process more efficient, precise, and environmentally friendly. Advancements like automatic grade control and slope adjustment have improved the precision of asphalt milling machines. Now, they can maintain exact surface specifications closely. Modern machines also have better operator comfort and safety features, such as more spacious cabs with ergonomic controls.

Q3: What types of materials are reused after asphalt milling?

A3: The key materials include recycled asphalt pavement or RAP, organic materials like plant-based lubricants, and high-friction additives that may remain in the milling machine. Nearly 100 million tons of asphalt material are recycled each year in the USA, creating new roads.
