Can you blacktop over concrete? Concrete is an excellent surface for a driveway, but what if you want to change the type of material? Blacktop can be used as a more durable and lower-maintenance option. Read on for some information about how to go about blacktopping over concrete.
What is blacktop?
Blacktop is a type of asphalt pavement. It is created by combining asphalt cement, aggregate, and other additives into a hot mixture that is poured and compacted onto a surface.
What are the benefits of blacktop?
Blacktop has many benefits:
- It is durable and can last for many years with proper maintenance.
- It is easy to maintain; a simple sweeping or hosing down will keep it looking clean.
- It provides good traction and grip, making it safe for drivers, cyclists, and pedestrians.
- It is affordable and relatively easy to install.
- It can be used for both residential and commercial applications.
Can you blacktop over concrete?
In some cases, yes! Blacktop can be successfully poured over concrete, but there are a few things to keep in mind. First, the concrete must be completely cured before blacktop can be poured on top. This means that the concrete should be at least 28 days old before work begins. Second, the concrete must be of adequate thickness and strength. If it is not, the blacktop may crack or heave. Finally, any bumps or irregularities in the surface of the concrete must be leveled out before blacktop can be poured.
Failure to do so may result in a bumpy or uneven surface. If you are unsure whether your concrete surface is suitable for blacktop, consult with a professional paving contractor. They will be able to tell you what needs to be done to make your surface ready for blacktop.
Why would you want to use asphalt over concrete?
There are a few reasons. First, asphalt is cheaper than concrete. It also doesn’t require the same level of maintenance as concrete, and it can be installed faster. Asphalt is also more flexible than concrete, which makes it better at absorbing impact. This can be important in areas that experience a lot of traffic or vibration. Finally, asphalt can be colored to match your desired aesthetic. This is not possible with concrete.
If you are looking for a durable and affordable paving option, asphalt is a great choice. Contact a local contractor to learn more about installing asphalt in your area.
Benefits of using blacktop instead of concrete.
In the world of asphalt paving blacktop is a term used to describe a higher quality product than traditional hot mix asphalt. The reason for this increased quality is twofold: First, if blacktop is not mixed correctly it can result in reduced pavement longevity and reduced structural capacity. Second, many municipalities have their own specifications for what constitutes a high-quality mixture.
These specifications often include limiting the amount of stone larger than 3/4″ at surface depth and using a lower allowable air void content at surface depths beyond 4 ½” (there are exceptions to these rules, but they are generally true).
So with these factors in mind let’s look at why you might consider using blacktop instead of conventional machine applied hot mix asphalt.
Hot mix asphalt typically has an air void content of 5-6%, whereas blacktop is usually only 3-5%. This reduced air void content is one reason for its greater structural capacity. Additionally, the use of recycled materials, such as old tires or old concrete can save hundreds to thousands of dollars per ton over virgin aggregate through rebates offered by many recycling companies.
Many contractors are hesitant about using these recycled products due to concerns about their effects on compaction and strength development, but modern recycling equipment includes a drum arrangement that reduces the chance for segregation and ensures a quality product. The addition of polymer modifiers allow you to achieve a high degree of workability with a binder containing a 50% recycled product blend without compromising pavement performance.
FAQs about blacktop over concrete.
What are the benefits of asphalt over concrete?
Asphalt is more economical, easier to work with and is less disruptive during installation. It also provides a wider range of design choices for both pattern and color. Asphalt driveways are preferred in climates where the weather is very cold or very hot because its flexibility compensates for expansion and contraction caused by temperature changes.
Why should I choose blacktop driveway construction instead of concrete?
Asphalt has stood the test of time as one of the most popular surfaces used on new driveways today. After all, it’s not called blacktop without reason! The color brings warmth while at the same time blending seamlessly with nature’s surroundings, whether forested or open fields. The fact remains that as a result of its installation process, as well as its composition and resilience, asphalt is the perfect driveway material. By comparison, concrete driveways have their own set of benefits – most notably the fact that they are extremely sturdy and will last a lifetime requiring very little maintenance.
How about the cost? Is asphalt more affordable than concrete?
Installation costs for both materials can vary from project to project depending on location and site specifics, but overall asphalt is less expensive simply because it requires less labor time under normal conditions. The surface with which you’re working also has a big influence on this aspect of your budget.
If you are looking to install a new paving surface over an existing concrete slab, there are some things to keep in mind. Concrete is durable but can be damaged by extreme heat or cold so it’s best if your job does not need the use of either during installation. It may also take longer for concrete slabs to dry out before being sealed properly and this will affect how long the blacktop needs to cure prior to traffic on it.
