In spite of what people think, asphalt paving and sealcoating are two different processes involved in installing a new surface, repairing an existing surface, and maintenance of asphalt pavement. However, asphalt paving and sealcoating can be done on the same surface to achieve different objectives. This, however, depends on different factors. 

All in all, you should understand that both paving and sealcoating are essential processes required for the proper maintenance of asphalt pavements. And these two processes must be done correctly by professionals for the best and most durable results. 

Asphalt paving

This is a term used to describe the process of applying hot asphalt to a parking lot, driveway, or roadway. Also, this term is used to describe the process of creating a new pavement or repairing an existing one. Asphalt paving processes can range from a simple overlay to complete resurfacing. 

How long does asphalt paving take?

The time it would take to pave an asphalt driveway, or parking lot depends on the size of the project. However, most projects can be completed in a day or two.

In this section, we shall discuss in detail the asphalt paving steps. Let’s delve in. 

Step 1 – Preparing the surface

The first step in every asphalt paving project is to prepare the surface. This process involves grading and leveling the area where the new pavement will be installed. Also, any existing pavement that needs to be removed will be removed at this stage. 

Step 2 – Laying the subgrade

After preparing the surface, the next step is to lay the subgrade. The subgrade is the layer of material that lies beneath the asphalt pavement. This layer provides stability for the new pavement. 

Step 3 – installing the base course

The next step in asphalt paving is to install the base course. The base course is a layer of material on top of the subgrade. This layer provides a smooth surface for the new asphalt to be installed. 

Step 4 – Paving the asphalt

Once the base course has been installed, the next step is to pave the asphalt. This process involves installing hot asphalt on top of the base course. The new pavement will then be leveled and compacted. 

Step 5 – Finishing the surface

The final step in asphalt paving is to finish the surface. This process involves applying a layer of sealant or coating to the new pavement. This will protect it from weathering and fading.

Sealcoating 

Asphalt sealcoating is the process of applying a sealant to asphalt pavements to protect them from water damage, harsh weather elements, and oil and chemical spills. Besides, sealcoating is done to improve the curb appearance of a property. 

Unlike asphalt paving, sealcoating isn’t part of asphalt repair processes. Rather, it’s a maintenance process. Any problems with your asphalt surface will not be solved through sealcoating. 

Reasons to sealcoat a surface

  • Prevents weathering – One of the main benefits of sealcoating is preventing weathering. The sealant protects the surface from the sun, rain, and snow. This helps to keep it looking new for years to come. 
  • Keeps the surface smooth – Sealcoating also helps to keep the surface smooth. Over time, asphalt can become rough and pitted. The sealant helps fill in these pits and restore the surface to its original condition. 
  • Prevents fading – Sealcoating also helps to prevent fading. The sealant protects the surface from the sun’s UV rays, which can cause it to fade over time. 
  • Reduces maintenance costs – Sealcoating can also help to reduce maintenance costs. Protecting the surface from weathering and fading will require less frequent repairs. This can save you time and money in the long run.
When is the best time to sealcoat an asphalt surface?

According to the experts from ABС Paving, sealcoating contractor from Florida, the best time to sealcoat an asphalt surface is when it’s 6 months old after paving. The sealant will adhere better to a clean, smooth surface. However, even old asphalt surfaces can be sealcoated as long as they are still in good condition.

The first step in every sealcoating project is to prepare the surface. This process involves grading and leveling the area where the new coating will be applied. Also, any existing pavement that needs to be removed will be removed at this stage. 

How to prepare asphalt surface for sealcoating. 

  • Checking for cracks – The first step in preparing an asphalt surface for sealcoating is to check for cracks. If any cracks are found, they will need to be repaired before the sealant can be applied. 
  • Cleaning the surface – The next step is to clean the surface. This process involves removing all of the dirt, dust, and debris from the area. The surface should be cleaned thoroughly before applying the sealant.
Step 2 – Applying the primer coat

The next step in sealcoating is to apply the primer coat. This coat helps the new coating adhere to the surface. 

Step 3 – Applying the sealant

Once the primer coat has been applied, the next step is to apply the sealant. This process involves applying a layer of sealant to the surface. The new coating will then be leveled and compacted. 

Step 4 – Finishing the surface

The final step in sealcoating is to finish the surface. This process involves applying a layer of topcoat to the new coating. This will protect it from weathering and fading.
