Introduction

Asphalt milling, also known as cold planing, is a process used to remove a portion of the surface of a paved area, such as a road or parking lot. This process is typically done to prepare the surface for a new layer of asphalt or to repair damage to the existing pavement. In this glossary, we will explore what asphalt milling is, how it is done, and the benefits of this process.

What is Asphalt Milling?

Asphalt milling is a process in which a machine called a milling machine is used to remove the top layer of asphalt from a paved surface. This machine has a rotating drum with carbide teeth that grind and remove the asphalt material. The milled asphalt is then collected and can be recycled for use in new asphalt projects.

How is Asphalt Milling Done?

The process of asphalt milling begins with the milling machine being positioned over the area to be milled. The machine is then lowered onto the surface, and the drum begins to rotate, grinding away the asphalt material. The depth of the milling can vary depending on the project requirements, with some projects requiring a shallow mill and others requiring a deeper mill.

Benefits of Asphalt Milling

There are several benefits to using asphalt milling as a pavement maintenance technique. One of the main benefits is that it allows for the removal of damaged or deteriorated asphalt without having to completely replace the entire pavement surface. This can save time and money, as well as reduce the environmental impact of the project.

Recycling of Milled Asphalt

One of the key advantages of asphalt milling is the ability to recycle the milled asphalt material. This material can be reused in new asphalt projects, reducing the need for new raw materials and lowering the overall cost of the project. Recycling milled asphalt is also environmentally friendly, as it reduces the amount of waste that ends up in landfills.

Types of Asphalt Milling Machines

There are several different types of asphalt milling machines available, each with its own unique features and capabilities. Some machines are designed for small-scale projects, while others are capable of milling large highways and roads. The type of machine used will depend on the size and scope of the project.

Cost of Asphalt Milling

The cost of asphalt milling can vary depending on a number of factors, including the size of the project, the depth of the milling required, and the type of machine used. In general, asphalt milling is a cost-effective pavement maintenance technique that can help extend the life of a paved surface and reduce the need for costly repairs in the future.

Common Applications of Asphalt Milling

Asphalt milling is commonly used in a variety of applications, including road resurfacing, parking lot maintenance, and pavement repair. This process is versatile and can be used on both small and large-scale projects, making it a popular choice for pavement maintenance professionals.

Conclusion

Overall, asphalt milling is a valuable pavement maintenance technique that offers a range of benefits, including cost savings, environmental sustainability, and improved pavement performance. By understanding the process of asphalt milling and its applications, pavement maintenance professionals can make informed decisions about when and how to use this technique.
