Bitumen or much commonly known as asphalt is one of the most used forms of petroleum. This sticky, black and highly viscous fluid is the reason why fewer people end up dying due to vehicular accidents. It is usually poured on top of the concrete road which is usually made up of sand, gravel and a sealant like cement. Since road safety is something that concerns everybody, this article will tell you what and how asphalt is made.
What is asphalt?
As stated above, asphalt or bitumen is a crude form of petroleum. Petroleum is produced out of the fossils compounded for millions and millions of years. So, every time you fill your car up with gas or stroll down the asphalt driveways Melbourne has, thank the dinosaurs!
Asphalt is dubbed as the flexible pavement because of the way it distributes weight and causes to increase friction. This is very important because friction allows a moving object to stop with ease. As you remember your physics lessons in high school, the first law of motion says that “a body in motion will remain in motion unless acted upon by an external force”. That external force is the friction provided by the asphalt driveways Melbourne has at present.
How is it made?
Asphalt or bitumen can be made both naturally and artificially. However, there is something in common between the two that makes them all the same: they are residues of the distillation process that was executed on the crude petroleum oil that is harnessed through oil fields. The naturally made bitumen however is a product of high heat, pressure and fossil fuel. Crude bitumen or the natural asphalt has the same consistency and viscosity that of molasses. If you have seen dinosaur movies where dinosaurs are stuck in tar, then you are seeing natural asphalt or bitumen. Read more at Asphalt Melbourne.
Despite the common notion that asphalt is solely used on roads, it has actually a lot of applications. As stated above, asphalt is regarded as flexible pavement. This means that it is able to distribute weight evenly through the surface and can bend and wave to prevent it from breaking. Unlike concrete roads, the asphalt driveways Melbourne has can withstand earthquakes and constant wear and tear from huge trucks and vehicles. Here is a list of the other uses for asphalt:
- Recreation (Friction agent for theme parks, tennis courts, bike lanes and running tracks)
- Industrial (Factory floors, adhesive for some materials, can be used as fuel as well)
- Agriculture (Can provide solid flooring for pig pens, greenhouses and farm roads)
Things to remember
If you are looking for somebody to help you with your asphalt concerns, do your homework! A lot of asphalt contractors in Australia are able to provide you with information through their websites and pamphlets. In order to get the best commercial asphalt services Melbourne has, have a little talk with the construction men themselves. They know it better than anyone else because they are the ones responsible for every single asphalt driveway Melbourne cost available. Lastly, get a portfolio from them to help you assess their level of work. So, be smart!
