Asphalt milling, also known as pavement milling, is the process of removing the top layer of an existing asphalt surface to prepare it for a new layer or to improve its surface. This technique is commonly used by asphalt contractors around the country. By milling the existing surface, contractors can eliminate the need for complete repaving, making it a cost-effective solution for extending the life of a road or pavement.

The Environmental and Economic Benefits of Asphalt Milling

One of the primary benefits of asphalt milling is its ability to recycle old asphalt into new projects. By milling the old surface, the material can be collected and reprocessed at an asphalt plant. This not only reduces the environmental impact but also cuts down the cost of acquiring new materials. According to the National Asphalt Paving Association, of the 2.6 million miles of paved roads in the U.S., over 94 percent are surfaced with asphalt. This highlights the significance of milling in maintaining the country's extensive network of asphalt roads.

The Milling Process and Equipment

The process of asphalt milling involves specialized machinery known as milling machines or cold planers. These machines feature a rotating drum covered with teeth made from robust materials like carbide. As the drum rotates, it cuts and grinds the asphalt surface. From our experience, the depth of removal can be adjusted to suit different project needs, ranging from a few millimeters to several inches. This flexibility is crucial in addressing various pavement issues, from minor wear and tear to significant surface damage.

The Enhancement of Safety and Performance

Moreover, asphalt milling helps in improving the overall safety and performance of paved surfaces. By addressing surface irregularities such as ruts and cracks, milling restores smoothness and traction to the roads. This is particularly important for high-traffic areas where safety is a paramount concern. Additionally, milling helps maintain proper drainage, preventing water accumulation that could lead to further deterioration of the pavement structure.

Asphalt milling is an essential process in modern road maintenance and construction. It offers a sustainable and economical solution for resurfacing roads, reducing the need for new materials, and enhancing the longevity of existing pavements. Whether by improving road safety, promoting environmental stewardship, or ensuring cost-efficiency, asphalt milling continues to play a vital role in maintaining the integrity of our road infrastructure.
