If you are like most commercial building owners and managers, you probably don’t know a lot about the asphalt laying process. You know that you need asphalt for your parking lots and driveways. You also probably know that asphalt needs regular maintenance. But, do you know the different processes? If a contractor brings up asphalt milling, will you know what they are talking about? We can help! Here is what you need to know about asphalt milling.
Asphalt Milling Basics
The purpose of asphalt milling is to remove the top layer of asphalt in a parking lot, driveway, or other surfaces without disturbing the subbase. The reason for asphalt milling is to provide a surface to lay new asphalt down without increasing the height of the area. If you have a firm foundation, this is a good way to avoid replacing the entire parking lot. The milling process prevents disturbing curbs or drainage.
Asphalt Milling Process
The process of asphalt milling includes a milling machine. These machines come in a variety of sizes to undertake a variety of different jobs. Larger machines may be able to cut up to 15,000 square yards at about 75 feet per minute.
Asphalt Milling Machine Components
There are three components to the asphalt milling machine. There is the cutting drum that rotates cutting heads across the asphalt’s surface. This component chews up the asphalt, then the second component, the vacuum, sucks up the material. The conveyance system is the third component and it is responsible for moving the material to the dump truck. Once the milling machine removes the asphalt, the contractors can sweep and clean the surface. Once clean, the new asphalt can bond to the old asphalt.
Asphalt milling is less invasive and a lot more cost-effective than replacing the whole parking lot. If you need work done on your commercial or industrial parking lot, contact NVM Paving & Concrete today by calling 703-423-0471 or emailing us to find out more!
