4 Different Asphalt Repair Options

Asphalt is prone to a variety of damages due to poor installation, failure to perform regular maintenance, and exposure to dangerous elements. Therefore, it is essential to repair pavement damages as soon as possible to avoid more extensive and costly repairs in the future. Our experts on asphalt paving in Dallas, Fort Worth, TX, offer the following restorations you may need for your asphalt surfaces.

New installation

New asphalt installation is a fresh start for your paved surface. It usually consists of the following process:

Demo and removal

You must start with removing and disposing of the existing asphalt surface. Then, you can recycle the existing asphalt materials and use them in future paving processes, saving you costs on materials.

Grading and sloping

Before installing your new asphalt, the surface must be graded to allow water to drain off of the pavement and into grassy areas. In many cases, contractors need to reshape the landscape to provide a sloped surface to help redirect water flow.

Subbase prep

The subbase of an asphalt structure is the bottom layer that supports your new asphalt pavement.

Adding a binder layer

A binder layer includes a mixture of large aggregate and oil that creates strength and durability. This step should be completed before adding a proof roll.

A proof roll is a way to test whether the underlying surface has the strength to support the new asphalt surface. If soft areas are discovered during the proof roll, they can be repaired with undercutting. Undercutting involves digging 2 to 3 feet below the surface to replace softer soil with strong aggregate materials.

New surface installation

This step involves laying the new asphalt materials.

Final roll

This step involves smoothing and compacting the asphalt for a finished product.

Overlay

Asphalt overlay is best described as a large patching job completed over an expanse of asphalt. This is typically required when existing asphalt surfaces show signs of potholes and cracking but not enough to require a complete asphalt replacement.

Patching

Patching is the process used to repair potholes. These are variations in methods for patching, but the overall idea typically follows these steps:

Damaged pavement removal

Depending on the nature and size of the damage, different tools will be required.

Pothole cleaning

It is essential to remove all debris. In addition, if there is any plant life present, be sure to remove it, root and all.

Foundation repair

You need a sturdy base in place to avoid any future problems.

Pothole filling

The type of asphalt used in this step will depend on the size of the pothole and weather conditions. Usually, cold or hot mix asphalt will be used.

Tamping

The pothole should be overfilled slightly then tamped down. Different machinery and tools can be used depending on the pothole's size.

Milling

Milling is a process used to remove an asphalt surface’s top layer without harming the subbase. This is an excellent option if your subbase is functional and only the top layer requires repairs. It costs a fraction of full reconstruction because you only remove and replace the top layer. The whole process can be completed relatively quickly.

These are just a portion of the repairs your asphalt surfaces may require. Contact us today for more information on asphalt paving in Dallas, Fort Worth, TX.
