When you need a parking lot paved, many companies can help. If you have not done this before, it may take some time to research which company is the best for your needs and budget.
With so many options available online to choose from, it's important to do everything you can upfront so that the paving process goes smoothly. This guide will provide an overview of what is the process of paving a parking lot.
Preparation and Permits
Prior to paving a parking lot, you will need to prepare the surface. This often includes grading and compacting the ground and installing any necessary drainage features. In some cases, you may also need to obtain permits from your local government before starting the project.
The Complete Process to Pave a Parking Lot
In this section, we will look at each step of the parking lot paving process.
Step 1: Demolition and Removal of Existing Surface
The first step in any asphalt paving project is the demolition and removal of the existing parking lot. This process can vary depending on the size and scope of the project, but it typically involves removing the existing asphalt or any pavement surface, as well as any grass, trees, or other landscaping features that might be in the way.
Once the area has been cleared, it's time to start excavating. This step is vital for two reasons: first, it gives the pavers a chance to inspect the underlying soil condition.
Second, it provides an opportunity to make any necessary repairs or adjustments to the grade of the land. Once the excavation is complete, the area is ready for paving.
Step 2: Grading and Sloping
The next step is to grade and slope to make the site a stable surface. This is important for drainage and ensuring that the pavement will be level and stable.
There are a few different ways to slope a parking lot, but the most common method is to create a series of flat planes that slope gradually from the lot's edges toward the center.
Step 3: Preparation for the Sub Base
After grading, the next step is to prepare the surface for the sub-base. This involves spreading a layer of gravel over the entire area and compacting it using a roller. The sub-base provides a stable foundation for the pavement, and it's important to make sure that it's evenly spread and well-compacted.
Step 4: Undercutting, Proof Roll, and Repair of the Sub Base
Once the sub-base is in place, it's time to start installing the pavers. The first step is to undercut the surface, which means cutting into the underlying soil and gravel to create a level foundation for the pavers.
Next, the proof roll is performed. This is a process where a roller is used to apply pressure to the pavers to ensure that they are properly bonded to the sub-base.
Finally, any necessary repairs to the sub-base can be performed. This might include filling in any holes or cracks and leveling out any uneven areas.
Step 5: Surface and Binder Course
With the sub-base in place, it's time to start laying the surface course. This is the top layer of pavement, and it can be made from a variety of materials, including asphalt, concrete, or brick.
The surface course should be evenly spread and well-compacted, and it's important to make sure that the pavers are in alignment and level with each other.
Step 6: Installation of the New Asphalt Surface
The most common type of surface course is asphalt, and the final step in paving a parking lot with an asphalt paving machine is to install a new asphalt surface. This involves spreading a layer of hot asphalt over the entire area and then using a roller to compact it.
In this asphalt installation process, once the newly laid asphalt has cooled and hardened, the parking lot is ready for use.
4 Attributes of Good Commercial Parking Lot Paving
On an average day, how many cars are on the street? How many people are walking around? The answer to both of these questions is a lot. This is why when paving a parking lot, these are the four specific things that should be taken into account:
Smooth Integration of the Previous Pavement
If a parking lot is being repaved, the new pavement should match the old as closely as possible. This creates a smooth transition for drivers and pedestrians, making the lot look more professional.
A Decent Gravel Base
The gravel base is one of the most important parts of the paving process, as it provides a stable foundation for the pavement. The base should be well-compacted and even, and it should be free of any large rocks or other debris.
With so many cars on the street, it's essential to ensure that the parking lot can drain properly. This means installing a system of gutters and drains and ensuring that the entire surface is sloped towards the drains.
Give Attention to Details
The best parking lots are well-maintained and free of any blemishes. This means paying attention to the details, such as the alignment of the pavers, the smoothness of the surface, and the overall appearance of the lot.
There might be some questions that come up during the paving process, and here are some of the most common ones:
What is the best paving for parking lots?
There is no one-size-fits-all answer to this question, as the best type of paving depends on the specific needs of the lot. However, asphalt is often a popular choice for parking lots, as it is durable and affordable.
How deep should the gravel base be?
The depth of the gravel base will vary depending on the type of pavement being used. However, a good rule of thumb is to make sure that the base is 4" to 6" inches deep.
Can I drive on the new pavement right away?
Expert asphalt paving contractors suggest that it's best to wait until the new pavement has had time to cool and harden before driving on it. This can take anywhere from several hours to a few days, depending on the type of pavement. Especially on hot days, it is important to let the asphalt cool down for more than a day.
Considering the amount of traffic that a parking lot handles daily, it's essential to take the time and do it right when paving one. By following these steps and taking the four key attributes, you can be sure that your parking lot will be up to par.
