Understanding Asphalt Milling Machines
What is Asphalt Milling?
Asphalt milling is the process of removing the top layer of asphalt pavement. This technique is essential for road maintenance, allowing for the repair and recycling of worn-out surfaces. By using specialized equipment, contractors can effectively grind the asphalt, preparing the road for a new layer.
How Asphalt Milling Machines Work
Asphalt milling machines utilize a rotating drum equipped with sharp, heavy-duty steel bits to grind the pavement. The ground material is then collected and can be reused, making the process environmentally friendly. The machines are designed to operate efficiently, ensuring minimal disruption to traffic and reducing waste.
