Parking lots see a lot of traffic, both from vehicles and pedestrians. And asphalt is mostly used because it is durable and easy to maintain, making it the best choice for this high-traffic area. Unlike concrete, asphalt can be repaired quickly if it becomes damaged.
But what is the correct mixture of asphalt for parking lots? Read more as we’re going to tackle this topic in today’s article.
Parking Lot Classifications
There are typically 2 types of parking lots: surface and structured. Surface parking lots are the most common, consisting of a paved area where drivers can park their cars. These lots can either be open or closed, and can include other features such as lighting, landscaping, and traffic control devices.
On the other hand, structured parking lots are enclosed facilities where cars are parked on multiple levels, typically with some form of mechanical device (e.g. elevator or ramp) to move cars between levels.
Different Pavements Require Different Mixes
Different pavements have different requirements for their mixture because of the traffic that will be using them. For heavily trafficked areas, such as parking lots or roads, a higher percentage of asphalt is needed to ensure a durable surface. This will help to prevent ruts and potholes from forming, and will also make the surface less susceptible to cracking.
While a lower percentage of asphalt is typically used for driveways and sidewalks, as these surfaces don’t see the same amount of traffic. It’s important to consult with a professional to determine the correct mixture for your project.
Correct Mixture Ratio
The correct mixture of asphalt for parking lots is typically around 95% coarse and 5% fine aggregate. This mix is strong and durable, able to withstand the heavy weight of vehicles without cracking or breaking. The high percentage of coarse aggregate also makes the asphalt more slip-resistant, which is more important in an area where there is a lot of traffic going on.
If you are responsible for maintaining a parking lot, knowing the correct mixture is crucial to ensure durability and the safety of the structure for all users for many years.
Types Of Asphalt Mixes To Choose From
When it comes to paving parking lots, many factors come into play. One of the most important is the type of asphalt to be used. There are a few different types of asphalt available that can be used for parking lots and these are the hot mix, cold mix, and chip seal.
Hot mix asphalt is the most common type of asphalt used for paving. It is made by combining aggregate (crushed stone, gravel, and sand) with bitumen (a petroleum product). This mixture is then heated and placed on the pavement. Hot mix asphalt is very durable and strong.
On the other hand, cold mix asphalt is a less common type of asphalt. And it is made by mixing aggregate with emulsified asphalt. The mixture is then placed on the pavement and compacted. Cold mix asphalt is not as durable as hot mix asphalt, but it can be used in a pinch.
Lastly, chip seal is a type of asphalt that is made by spraying a thin layer of bitumen on the pavement and then covering it with a layer of aggregate. Chip seal is a cheaper alternative to hot mix asphalt, but not as durable.
When choosing the type of asphalt to use for your parking lot, it is important to consider the climate, traffic, and budget. Hot mix is the most durable among the 3 and can withstand heavy traffic, but it is also the most expensive. While cold mix asphalt is less durable but is ideal in regions with colder climates. Chip seal is the cheapest option but not as durable. Ultimately, the decision comes down to what is most important for the given project.
Average Thickness Of Your Parking Lot
When it comes to parking spaces, there is no one-size-fits-all answer. However, there are some general guidelines that can help you determine the right thickness for your parking space.
Most experts recommend an average thickness of at least 8 inches for a parking space. This will provide plenty of room for cars to maneuver and park, while also protecting the asphalt from wear and tear.
However, if you live in an area with extreme temperatures, you may need to increase the thickness of your parking space. In hot climates, for example, the asphalt can start to soften and become more damaged easily. In these cases, a thickness of 10-12 inches is usually best.
How About The Thickness Of The Asphalt Layer
Every project is different and will require a unique approach in order to ensure the safety and functionality of the lot. However, in general, a good starting point is to aim for a thickness of at least 2.5 inches as this will provide a sturdy surface that can withstand heavy traffic and weather conditions. If you’re not sure about the exact thickness that you need, it’s always best to consult with a professional contractor like JR Paving & Construction Co., Inc. who can assess your specific project needs.
Why Pouring The Correct Asphalt Mix Should Only Be Done By A Qualified Contractor
Parking lots are exposed to all kinds of punishment, so it’s important that they are paved with a durable material like asphalt. And asphalt paving must be done by a professional contractor for 2 specific reasons. First, the asphalt needs to be heated and then poured in place. If this is not done correctly, the asphalt will not be smooth and level.
Second, the asphalt needs to be compacted properly to ensure that the parking lot will last for many years without requiring repairs.
Hence, selecting the right contractor for the job is essential. And here are a few tips on how to do just that:
- Look for a contractor with experience in paving parking lots and pouring the correct asphalt mixes. They will definitely have the knowledge and tools to get the job done right the first time.
- Request quotes from several contractors in your area. And be sure to ask about their experience, process, and materials they recommend for your project specifically.
- Get references from each contractor you’re considering and follow up with those references. Make sure you’re comfortable with the contractor’s work ethic and quality of their previous projects.
- When you’re narrowed down your options, select the contractor you feel most confident in and that provides the best value for your money.
Following these tips should help you find a reputable contractor that can get your parking lot paved correctly with the right asphalt mix.
