When looking at the various types of materials used for surfacing projects, it’s more than likely that you will stumble across various key terms that might leave you confused. One of the most common confusions is with asphalt and bitumen, more specifically, what is the difference between the two?
It’s unlikely that you will come across these terms unless you are planning on surfacing an asphalt driveway, but it’s often the case that people assume bitumen is the same as asphalt – when they are very different.
To keep it simple, bitumen is the liquid binder used to hold the asphalt together. The process usually entails spraying a surface layer of bitumen on the driveway surface, where aggregate is then covered across and spread evenly to create a suitable surface. This is then repeated to guarantee a two-coat finish, which will then be flattened to create a smooth surface for vehicles. In this case, the asphalt is the overall composition of aggregates, sand and bitumen, which is the key difference that people confuse.
As mentioned above, asphalt is the overall result of mixing the raw materials mentioned above. The primary reason that asphalt is so popular is due to its sheer durability compared to the low costs for materials and production, making it a very cost-effective solution for surfacing projects such as driveways and roads.
Bitumen is in fact a naturally occurring raw material, where it also plays a key role in several road surfacing projects other than asphalt. However, once it has been extracted it is then processed to become the adhesive that road surfacing contractors use for their projects. It’s also worth noting, bitumen can also be used for road surfacing without the need for aggregate or sand-like asphalt uses, though they lack the quality and durability as asphalt surfaces.
