Asphalt milling has become a crucial part of a road owner’s strategy for extending the life of their infrastructure. Keeping cars driving on smooth roads by removing worn surfaces and replacing them with freshly paved asphalt saves money in the long run. Learning how to use such construction equipment effectively is essential for contractors who want to complete paving projects successfully.
What Role Do Milling Machines Play In Proper Paving?
Milling machines aim to prepare the ground for paving crews to do their best work. The milling crew’s job is to build a blank canvas for the paving crew to work on. The paving team would have a better chance of paving it correctly if the milling was done correctly.
Effective Communication Is the Key to Efficient Job
The office has complete details, which are then passed on to the supervisor or foreman, and finally to the milling team. But it doesn’t end there; managers will need to speak with dump truck drivers, for example, to explain how they intend to approach the job to complete it safely and efficiently. They’ll keep the trucks full of uniform material coming from a well-kept cutter drum spinning at a constant rpm.
The constant speed is determined by the surface being milled, the width of the cut, the form of pavement, the makeup and function of the pavement, and other factors.
The project manager should take the milling machine operator aside and show him the final product version. Instill in the operator a sense of pride in their job. While the boss desires “more lots,” he also desires a job well done.
The Magic of Maintenance
Milling machines are made to do one thing: rip up anything they come across. They take a beating in the process, so it’s critical to ensure that maintenance is performed regularly and correctly. Crews need the best milling machine for the job to ensure that performance is maximized. Small machines are great for minor jobs such as curb reveals or slashing around a utility hole.
Larger patch jobs can necessitate using a small or mid-sized computer, while complete replacement jobs necessitate the use of big machines. It’s easier to fit milling machines to the work that needs to be done when you know the job size and specifications.
Allow Well-Trained Employees to Do Their Jobs
Milling machines offer a high center of gravity and are sensitive to slope, so keep that in mind. On the unit, there is a slope degree. The unit will topple if you walk past it. At the very least, you’ve destroyed a half-million-dollar machine; at worst, you’ve crushed staff or motorists. Paying attention to the computer is one way to do a good job. It will inform you when your teeth need to be replaced.
Instead of considering the cost of 18 to 19 teeth today and 16 to 17 teeth tomorrow, consider the ragged cut job you’ll get if you let teeth fall out. The surface would be appropriately set up for the paving workers if the cut job is uniform all the way through. Please don’t be stingy about the teeth of your construction equipment and replace them when necessary.
Change Your Depth-Checking Routine
The groundsman usually inserts the ruler from the back of the milling machine’s cutter drum to determine the depth. They will enter the cutter drum housing with their foot brushing some material away before leaning in to insert the ruler. This tradition must come to an end.
If the cutter comes into contact with a large rock, a utility hole cover, or any other obstacles that the crew had not expected, it will kick back and run over the worker. They might lose their life as a result of this action. There is a better depth search at the back of the unit.
Both ground staff and the milling machine operator will be aware that the ground man is taking the depth check as they approach the back of the machine, inserts the ruler in the lane, and reads the measurement with full touch. Please keep in mind that this form of maneuver necessitates contact so that all parties involved are aware of where they are and what they are doing.
Allow enough time for the tracks to get in and the hydraulics to respond when the machine engages in the cut and starts to move. Beginning too soon will lead to the cutting head dropping too far, which can potentially cause a new hole in the track.
