We've helped improve severely damaged asphalt through pavement milling throughout the Middle Tennessee area. The process is ideal for parking lots, driveways, and roads that suffer from severe cracking in both the substrate and the surface. Both of which can lead to severe foundation issues and shorten the lifespan of your asphalt paving. With the pavement milling service, we can help you:

Repairing Asphalt to Your Property
When it comes to your parking lot or driveway, you'll want to use a building material that is durable and long-lasting. Many options on the market have characteristics that lend themselves to a longer lifespan, but asphalt is a superior choice due to its makeup. The product is formulated from a mixture of gravel and a binding agent. The gravel or stone is a naturally occurring source that is virtually indestructible. It can handle heavy weight and withstand the friction that comes from car tires.
The binding agent, usually something like tar, is a flexible material that gives the product movement and holds the gravel in place. Movement is beneficial because it allows for a healthy amount of expansion and contraction to reduce the chances of unnecessary cracks or holes forming. There are times when asphalt is exposed to extreme fluctuations in temperature the material will become brittle. Cold weather can add tension, and UV rays will absorb the healthy oils. If proper maintenance hasn't occurred, blemishes to the surface will materialize into divots, cracks, or crumbling. RoadBuilders can use milling techniques as repairing option that is both economical and environmentally beneficial to property owners.
How the milling process works
Pavement milling, sometimes called cold planing, is a service that removes a paved surface that is beyond repair. Milling has the option to remove just the exterior or the entire pitch of the asphalt parking lot or driveway depending on individual needs. Through the use of heavy machinery called a milling machine, a network of drums and cutters grinds away at and removes the asphalt. The extracted material is automatically loaded to a conveyor belt attached to the device. Water is often introduced during the process to keep temperatures down and to minimize the amount of dust that becomes airborne from the grinding of the asphalt.
Uses for pavement milling
Most pavement work is tackled one of two ways, through an overlay or by completely repaving. Overlays are any type of surface repairs such as resurfacing, crack filling, or asphalt patching. These options work best for minor blemishes. A complete repaving project takes place when there are damages to the substrate that is beyond minor rehabilitation. Distresses to the asphalt improved by milling include:
Bleeding - When the pavement makes it way to the surface because of too much gravel in the mixture, hot weather, or poor quality.
Raveling - When the aggregate is knocked loose and separated from the binder. Usually identified by having small to large pieces of asphalt crumbles.
Rutting - Sometimes called divots, rutting is characterized by low spots in the pavement from supporting the weight of heavy cars.
Shoving - Shoving will add grit to the pavement and is identified by the washboard-like effect on the surface.
Ride Quality - An uneven surface that makes it challenging or difficult for drivers to use the asphalt.
Damage - Direct flaws to the aggregate caused by such things as road accidents or fires.
You can use milling as an environmentally conscious method for repaving your asphalt. The process recycles the materials already present in your pavement and allows for it to be reused when a new parking lot or driveway is laid down.
