In this article, we aim to answer the question of how asphalt roads are made. We’ll start by looking at the definition of asphalt, a brief summary of the history behind their creation, and then move on to explaining some of the processes involved in making asphalt roads.
What is Asphalt?
Asphalt is a sticky, black semi-solid form of petroleum. It may be found in natural deposits or it can even be refined and classed as “pitch”. The word “asphalt” originates from Ancient Greek “asphaltos” which means “secure.”
Asphalt is a versatile material with many uses. It can be used in the construction of roads and bridges, for waterproofing products such as roofing felt or building seals on flat roofs. The most common use (about 70%) focuses around creating asphalt roads, which require durability against traffic wear and tear.
Asphalt Road Installation Process
Asphalt roads are a crucial part of our society. You can find asphalt roads in residential areas, commercial districts, and industrial zones. Asphalt is often used because it is cheaper than concrete and more durable than gravel or cinders. The installation process for an asphalt road is rather complicated and requires professionals to get the job done correctly.

The process of installing asphalt roads begins with DEMOLITION. This is a necessary step in the process as it clears debris and prepares the surface for installation. It is more difficult to install asphalt on top of gravel or cinders because the existing material needs to be removed. The demolition process, including removing any hazardous or unwanted material from the site. It may take awhile for this work to be done as it involves heavy machinery that requires careful handling due its size and weight depending on what task needs performed – like an asphalt pavement company using bobcats (small 4 wheel drive vehicles) with forklift trucks backing them up. If you’ve ever seen asphalt parking lot paving in action, you know what this looks like.
Once all debris is clear, it’s time for GRADING AND SLOPING. When it comes to paving a road, there’s no such thing as an easy feat. One must first grade and slope the surface before they can lay down their asphalt or concrete for optimal drainage purposes; without these precautions taken by experts in this field everything will come tumbling down: potholes that never go away because you’re always driving over them (and wondering why your tires keep hydroplaning), cracks spreading like wildfire across all parts of our beautiful cityscape until one day we wake up with nothing left but crumbled brick walls at every turn.
Next step is the installation of the asphalt road’s SUB-BASE FOUNDATION. The sub-base provides stability by supporting the asphalt and also acts as a barrier for weather damage. A proper installation of this portion is crucial to increasing durability, ensuring that there are no leaks in your newly paved road!
After laying down the sub-base, there’s a need to PROOF ROLL the existing surface to ensure that this foundation is ready to support the asphalt mixture. The proof roll acts like a gravel test where loaded dump trucks are driven row by row over it and makes sure they’re in place properly so no areas flex more than an inch. If anything does, it will be repaired using an undercutting technique.
UNDERCUTTING is an important part of paving. Digging down into the soft surface and replacing it with more potent aggregate, or clay for that matter, creates a solid foundation upon which asphalt can be laid without disrupting any underlying sub-base materials like sandstones or quartzite – something we all know is essential if one wants their footing stable throughout construction!
After the sub base is approved, the next step is to add the BINDER LAYER. With an oil base, the binder helps to strengthen and preserve your asphalt road.
Next to the binder, the ASPHALT SURFACE is installed. Asphalt surfaces are typically black and smooth, but they also provide a safe ride for all of the different types of vehicles that travel on them. The surface consists mainly of sand with some oil mixed in it to create this beautiful finish we know as asphalt roads!
Once the pavers install asphalt road, there are a few FINAL TOUCHES that must be done. Most new roads connect to other surfaces and need extra grading or some kind of smoothing for transitions because of this connectivity with old runways. However many times it’s necessary in order to make sure everything looks uniform across all areas which includes grinding certain butt joints where appropriate-whatever is required by an area will depend entirely on what type terrain its located on.
The FINAL STEP in the process is to go over your new asphalt road with a roller truck. This ensures that there are no small bumps or loose materials, and everything has been picked up from under stones so you can’t find them when driving on it for years!
There are many benefits of asphalt roads, from being cheaper to more durable than other options.
