Yes, you can. You pave over a concrete driveway using either asphalt or pavers.
When you notice your concrete driveway crumbling or getting old, there are three things you can do. You can ignore the situation, you can remove the driveway, or you can pave over it.
Ignoring a crumbling concrete driveway will make your property look old and rundown. In some local government areas, it could attract fines or penalties. Therefore, it is not the right thing to do.
Completely removing your old concrete driveway is the right thing if it is too old, unbalanced, or poor quality. However, it comes at a cost and it will also take some time.
In many cases, the best thing to do when you notice a crumbling driveway is to pave over it. You can choose either asphalt or pavers to pave over your concrete driveway.
In this post, I will share with you details about paving over concrete using both asphalt and stone pavers.
What you really need to consider
Asphalt is perfect for driveways since it is something you can install quickly and it is much more weather-resistant, especially when compared to concrete.
Nevertheless, before you pave over your old concrete driveway, there is one big thing you need to consider and that is the base.
The very first thing you need to consider before you pave over an old concrete driveway utilizing asphalt is the base underneath the concrete.
You should only pave over an old concrete driveway if the base below it is strong and stable. The base must be strong and stable to ensure that the asphalt you are going to pour over it is solid and stable.
If the base is not solid, the new asphalt on your driveway will probably not look great when it dries. It will also not be very stable and you will need to repair it sooner rather than later.
The best base for asphalt is one that is very well prepared, compacted, and solid. If the base underneath your concrete is not well-prepared, your new asphalt pavement will start cracking very quickly. The cracking is often caused by the expansion and contraction, and the movement between the unstable parts.
Advantages of putting asphalt over concrete
If you are a homeowner who wants to switch from concrete to asphalt but you are not really sure, this is where you get convinced. Replacing concrete with asphalt has many advantages and it is something many homeowners do across the world.
Concrete has been in use for a long time but since asphalt started being used to make roads, pavements, and driveways, the world has never really looked back.
The three main advantages of putting asphalt over concrete are:
- Asphalt becomes very solid and durable when it dries
If you have more than one car or you expect to use your driveway a lot, you should make sure it is very solid and stable. Otherwise, the weight of your car will deform it or cause it to crack. The good news is that one of the advantages of asphalt is that it becomes very solid and durable when it dries.
- Asphalt is quite easy to maintain
For experienced professionals, asphalt is both easy to install and to maintain. In fact, compared to stone or concrete driveways, it is way much easier to repair and maintain an asphalt road or driveway.
- Asphalt remains attractive for years
The fact that asphalt is uniform and looks great makes it perfect for those who want their home to have a beautiful driveway. Furthermore, the fact that it can be easily maintained makes it continue looking fresh for a long time.
Disadvantages of putting asphalt over concrete
There are only two big reasons why you should not put an asphalt driveway over a concrete driveway. They are:
- Expansion joints
Normally, concrete driveways are made in sections. The sections have joints between them to allow expansion and contraction due to weather changes. By putting asphalt on a concrete driveway with wide joints, you will end up with cracks.
Since nobody wants to have a cracked asphalt road, professionals often only lay asphalt on concrete with not so wide joint gaps. Concrete driveways with wide gaps often do not get an overlay because of the joints and the cracking.
- Reduced longevity
Many people who invest in an asphalt driveway usually do so with the expectation that their new driveway is going to last for a long time. And this is usually what happens. It is what happens when the asphalt is laid on concrete or a base that is solid/stable.
In case the base is not solid or stable, the asphalt overlay often does not hold on very well and, generally, does not last for a long time.
How to do an asphalt overlay over concrete.
If the above information in this post inspires you to go ahead and do an asphalt overlay, you should contact the nearest asphalt road installation company. They will build for you a new driveway built to professional standards. If you cannot, follow the steps below:
- Create a base that is though and uniform.
- Grind the concrete to enable asphalt to stick it
- Put paving fabric on top of expansion joints
- Utilize properly hot asphalt for a good final appearance
