Building and maintaining roads is a complex process that demands precision at every stage to ensure long-lasting and safe infrastructure. One of the most important steps in this process is milling, a technique used to remove the top layer of an existing pavement. This is typically done using specialized machines designed for efficient surface preparation before new asphalt is laid. In this article, we’ll explore everything you need to know about road milling—its benefits, how it’s performed, and how to choose the best machine for your project.

What is Road Milling?

Road milling, also known as cold planing, is a crucial step in road construction where the top layer of asphalt is removed. This process helps prepare the surface for new layers of material, ensuring that the overall height of the pavement remains consistent. By eliminating worn or damaged asphalt, milling creates a smooth and even base for new materials to adhere to. It not only improves the quality of resurfacing but also preserves the original design and structure of the road, making it an essential part of any road maintenance or upgrade project.

Benefits of Road Milling

Milling offers numerous advantages that make it a popular choice in road construction and maintenance. Here are some key benefits:

  • Effective Road Maintenance: Regular milling helps eliminate cracks, potholes, and other surface imperfections that can worsen over time. It's a proactive approach to road care that keeps roads safer and more functional.
  • Surface Leveling: Milling corrects uneven surfaces, improving the overall ride quality and extending the lifespan of the road.
  • Improved Skid Resistance: By removing the smooth, polished layer of asphalt, milling increases surface roughness, which enhances traction, especially in wet conditions.
  • Extended Road Life: Milling allows for the addition of new asphalt over a solid base, significantly increasing the durability of the road against traffic and weather.
  • Cost-Effective Solution: The recycled materials from milling can be reused in new asphalt mixes, reducing material costs and minimizing waste.
  • Environmental Benefits: Milling promotes sustainability by reusing old asphalt, reducing the need for new raw materials and lowering the environmental impact of road projects.
  • Time-Saving: The process is fast and efficient, allowing large areas to be milled quickly, reducing project timelines and minimizing traffic disruption.

How Does Road Milling Work?

The milling process involves the use of large, specialized road milling machines equipped with rotating drums that grind and remove the pavement layer. These machines can adjust their depth and width based on the specific needs of the project. Operators control the speed and drum rotation to ensure a uniform and even surface removal, optimizing both performance and results.

Key Features to Consider When Choosing a Road Milling Machine

  • Adjustable Milling Width and Depth: Choose a machine that can handle different project requirements with flexible settings.
  • Precision Controls: Look for machines with advanced controls for accurate depth, speed, and slope adjustments.
  • Durability: Opt for a machine built to withstand heavy use and challenging road conditions.
  • User-Friendly Design: Machines with intuitive controls and ergonomic features improve operator comfort and productivity.
  • Ease of Maintenance: Choose a model with accessible parts and simple maintenance procedures to reduce downtime.
  • Fuel Efficiency: A machine that uses less fuel and has a smaller environmental footprint can lower operating costs.
  • Versatility: Select a machine that can be adapted with various attachments for different types of milling tasks.

Vacuum Forming Large Parts

Yiyongli is a leading supplier of custom plastic large part by vacuum forming process across a variety of industries.We can provide product design and manufacturing engineering assistance and is ISO 9001:2015 registered.


Vacuum forming is a very economical method for producing large plastic parts.It offers lower cost tooling and quicker prototyping than other technology. Vacuum forming is best choice compared to other manufacturing methods such as complex fabricated sheet metal or fiberglass, in large, complex shapes which require a lot of metal fabrication, grinding and finishing. Vacuum forming also compares favorably to injection mould in big plastic parts when small quantities.


Vacuum forming large parts are single component parts that come out of the actual product or a substantial part of the finished product. Usually they are enclosures or housings for equipment.Applications of vacuum forming large parts are seen in many industries, including medical equipment panels ,machine enclosures, engine covers for aerospace, transportation or construction industries, and rail-car interior trim or seat components.
