You may be an avid DIY-er, or perhaps you’re just curious. Whatever the case, learning about the process of asphalt paving is still pretty cool! So grab your notebook and pen – Asphalt Driveway Installation 101 is in session.
What Is Asphalt?
Asphalt is a combination of gravel, sand, crushed rock, and slags. These materials are bound together by a material called bitumen. Once the ingredients have been mixed, they are then baked to create the final asphalt product. Fun Fact: did you know asphalt is almost 100% recycled? Asphalt is also porous, allowing water to move into the ground rather than runoff.
Paving A New Driveway
- If you are installing a new driveway, the existing surface must first be removed. Once that is done, the area must be graded to ensure water will not sit on the surface of the new driveway.
- After grading, a supporting layer called sub-base is laid down. This layer assists in load-bearing, and is mostly made of crushed stones. If you are installing a new driveway on top of an existing one, it is imperative to lay a new sub-base for structural integrity.
- A binder layer made of bitumen and oil is then laid down, followed by a proof roll on top. This proof roll detects any soft areas that may need more sub base added to it.
- Once all your soft spots have been filled, it’s time for the new asphalt to be put in place! Asphalt is dumped and then rolled smooth, which helps to compact the material. Once the asphalt cools, it is ready for action!
But wait – there’s more! It is still wise to wait at least 24 hours before driving on your new driveway, and the asphalt must be cured between 30 (commercial) and 90 (residential) days to stop oxidation. Asphalt will eventually need to be resurfaced, but the good news is you can do it yourself using a driveway sealant!
