Have you ever seen an asphalt road? Have you noticed how they get compacted and smooth textured? Well, the asphalt compaction rollers give them this fine texture.
Asphalt is a mixture of aggregates, binders, and fillers. It is mostly used to make the roads on highways, airports, and runways. The asphalt roads are smoother and provide grip as well as a smooth run for the vehicles.
To make the asphalt roads smoother, we need to compact them very efficiently. For that purpose, construction workers use a specialized vehicle called rollers. The rollers are of different types that can be used according to the requirement of the project.
In this article, you will know about the different types of asphalt compact rollers.
-
Smooth drum rollers
We know that there is specialized equipment available for the construction job by renowned manufacturers, such as Cat wheeled excavator. Similarly, some famous brands also manufacture the rollers according to the need of the project. A smooth drum roller is one of that kind that is used in asphalt compaction.
The smooth drum rollers are used to tightly compact the asphalt material of the road which gives the final smoother and finishing look. The heavy drum applies high pressure on the road to make it compacted.
-
Static rollers
We can use these rollers in the compaction of different types of material like soil, silty, and other rough surfaces. However, it is best for asphalt compaction. We can also use the static rollers to give the final compaction to the paving train. The finishing rollers must be capable enough to provide the finishing result and remove the marks if left by the first or second rollers. The static roller makes the surface temperature up to 175°F.
-
Vibratory roller
The vibratory roller is quite similar to the wheel rollers with little variation. It has a little vibratory feature in the roller which gives a smoother texture to the rough and uneven surface. It compacts the asphalt mixture on the road very efficiently. They are available in double drums and single drums as well. the primary and intermediate compaction of the asphalt needs the vibratory rollers. However, the vibratory roller needs an optimized temperature of around 240°F, so that it can easily compact the asphalt on the road.
-
Oscillatory roller
It is quite different from the traditional compaction roller. In this type of roller, the drum is in direct and constant contact with the road, so that it maximizes the compacting effect.
-
Pneumatic roller
This is an advanced form of roller that uses a pneumatic-tired wheel in place of the drum. It applies the static compacting pressure on the road. The main purpose of this roller is to use it in the final finishing of the compaction. It helps in removing all the marks and other gaps to give the asphalt road a fine look.
Conclusion
Like a Cat wheeled excavator makes excavation easier, similarly, a roller makes compaction easier. Generally, the roads on highways, airports, and runways needs the asphalt compaction. The asphalt compaction rollers are of different types, you can read about them in detail, in this article.
