Asphalt milling machine

Asphalt milling machines have been around for over 30 years. Asphalt milling is the process of grinding up asphalt that can then be recycled. The process came about because many streets were getting higher and higher on curbs, and therefore drainage of the roadway was becoming an increasingly bad problem. The first production milling machines were called Galions after their manufacturer, Galion Iron Works. These machines resembled graders in shape and size. The difference was there was a 30-inch wide milling head where the scraper blade would normally be. The cutter drum was set into action by a rather large hydraulic pump.
Today's machines are much larger in scale. They also have elaborate conveyor systems to reduce the labor of picking up the material from the roadway. With many new types of Asphalt Aggregates in use today the Asphalt Cold Milling machines are often used today. These new production machines are designed to tackle any mix design they chew into. Some of the larger machines, depending on the depth of the cut, can cut close to 15,000 Square Yards a day, at 75 feet per minute.
Operating an Asphalt Milling Machine requires specialized training. Typically newer machines require 2 or more people to operate safely and efficiently . The operator stands on the deck of the machine and controls most of the machines functions, while another person on the ground controls the depth of the cut, keeps an eye out for obstructions in the roadway such as manholes and/or water valves. Operators typically learn by on the job training making the transition from operating on the ground to running the machine on top.
