What is asphalt milling?
Asphalt milling is the controlled removal of the existing asphalt pavement. Removal depth can range from the surface layer to the base course. Milling is a process that corrects and restores the original grade and smooths the surface for new asphalt resurfacing. Another term for asphalt milling is cold planing or profiling.

Does my parking lot need asphalt milling?
- Raveling - This is when the surface aggregate becomes loose and separated from the binder. Its like driving on a layer of pebbles.
- Cracking - There are many causes and types of cracks from alligator, longitudinal, transverse, block, reflection, slippage, and edge cracks.
- Bleeding - The result of asphalt binder seeping through the surface of the road.
- Rutting - These are depression spots that run a length in one direction.
- Shoving - A form of plastic movement, this is when the surface layer has a ripple or washboard texture.
- Uneven Surface - This can effect ride quality and cause extra wear on vehicles.
- Damage - Gashes or fire marks from vehicle accidents.
What are the benefits of asphalt milling?
- Milling can be repeated on the same surface over and over.
- The materials excavated are fully recyclable, the aggregate can be used in the new pavement on location or sent to a processing plant.
- Conventional asphalt removal can be costly and laborious, our state of the art equipment does it efficiently saving us time and you money.
- The grinding of the old asphalt results in a uniform and clean finish for the new layer to adhere to.
- As the milling takes place, the removed aggregate is simultaneously loaded into trucks for removal or recycling. This results in a clean and quickly completed construction site. We are able to work in sections to keep traffic flow in progress and your business operational.
What are the classes of asphalt milling?
- Class I - milling to remove surface irregularities
- Class II - milling to uniform depth as shown on site plans
- Class III - same as class II with the addition of cross slope
- Class IV - milling to the base or subgrade (full depth)
- Class V - milling to different depths at various locations
