What are the Best Methods and Products to Repair Asphalt?

The United States has numerous highways with asphalt as the main surface structure. However, multiple stresses apply to the asphalt on a daily basis from heavy vehicles to ultraviolet light. Cracks that appear along the asphalt surface must be repaired to maintain the structural integrity of the pavement. The United States Department of Transportation (DOT) has an established protocol for determining crack repair methods.

Repair Asphalt Characteristics

Asphalt is made up of sand, gravel, stones, and asphalt cement. This set forms a strong site surface. Asphalt provides a smooth and quiet ride, contributing to less fuel consumption compared to other surfaces. However, asphalt can deteriorate and cracks appear. Water can easily seep through the cracks, gradually undermining the structure of the asphalt.

Repair Asphalt Crack Sealing

The point is to determine if a crack is working, or moving, before determining the proper repair method. Crack sealing is typically used on cracks that are moving, or growing larger and larger, by 3mm (millimeters) or more each year. This constant movement significantly that resurfacing would be necessary will eventually break down the asphalt structure. In response, crack sealing involves placing a rubberized asphalt mix into and through the crack. The rubber component allows for minimal flex crack while still maintaining its overall structure.

Crack Filling

Crack filling is a method used for cracks that move or grow less than 3mm each year. These cracks are less volatile, requiring inexpensive asphalt fill compared to specialized rubber mix. Basic asphalt filler is applied into and through the crack to maintain its structure.

Weather

Both sealing and filling should be applied during mild weather, such as during the fall or spring. Crack contracts and expands in the heat of summer or the cold of winter. Additionally, a mild climate contributes to faster curing for a stronger overall bond between the cracked asphalt and the sealer or mix.

Economy

Sealing and filling methods provide a proper asphalt repair that will last for many years. Pavement only requires short, temporary closures during asphalt treatment, avoiding problematic traffic problems. These methods are also cheap compared to resurfacing or resurfacing the asphalt. DOT budget concerns have ensured specific guidelines on asphalt repairs for the most economical method possible for each driveway and crack set.

When the Damage to the Asphalt is Important

If your asphalt driveway is badly damaged, it’s best to hire an Asphalt repair Houston company that specializes in asphalt repairs.

The contractor will first mark out the area to be repaired. He will then cut the circumscribed surface with a saw to remove the damaged asphalt and avoid altering the rest of the surface. The professional will use a hot mix of asphalt and compact it to a thickness of 2 inches after compaction. Once the repair is complete, they can share their advice on how to maintain the asphalt of your driveway for longer life.

Asphalt Resurfacing

Over the years, the asphalt ends up suffering the effects of time. After 20 years, the surface becomes rough and impossible to sweep. It is then possible to perform a resurfacing.

However, for this to be possible, the granular base must be of good quality. The sparseness or absence of potholes and cracks can give clues in this regard. The drainage slope must also be maintained. Finally, the building and the ground level must be able to accommodate an additional thickness of asphalt.

A specialized Houston asphalt repair contractor will be able to perform quality asphalt resurfacing. This will first clean the surface to be covered. He will then apply a special coating to allow the new layer to adhere to the old one. The professional will then add the new layer of asphalt to obtain a thickness of 2 inches after compaction.
