The
asphalt bitumen is an organic binding material that is made from the
by-products of refined crude oil. It is non-toxic, a strong binder and
is reusable. Bitumen paving services are provided all around the world
due to the numerous advantages that they offer.
Bitumen Paving Services in Road Construction
There are a number of reasons to consider the application of bitumen in pavements. The reasons are as follows:
- Production of bitumen is economical- As bitumen is a by-product of the crude oil distillation process, therefore it is much more economical. Crude oil is composed of hydrocarbons. The primary products available are diesel, petrol, gasoline and high octane fuels. Therefore, bitumen paving services is certainly reasonable.
- The low melting point of bitumen- Bitumen has a low melting point that helps in fast surface dressing. The melting point of bitumen is 240 degree that it can be easily melted during laying the pavement. On top of that can be used safely for road work as well.
- Bitumen can be recycled- The bitumen can be melted back to its original state as bitumen has a favorable melting point. There are asphalt processing plants developed to treat and recycle the asphalt that is torn from old roadways. This old asphalt is mixed with fresh aggregate rock and new bitumen to make a strong asphalt material. No wastage from the end products.
- Bitumen has adhesive properties- Bitumen is non-toxic because it is free from hydrocarbons. To eliminate the impurities the by-product is refined. The adhesive nature of the bitumen keeps the road mix bind together under strong bonds.
- Bitumen has a variety of colors-
The traditional color of bitumen is usually black. Bitumen expands to a
variety of colors when certain pigments are added to heat resistance.
Advantages of Bitumen Paving Services
There are a number of ways in which Bitumen Paving Services can prove to be beneficial.
- Quick Repairs- Bitumen pavements come up with the options of quick repairs. They consume very little time for restoring the path for traffic and passerby.
- Smooth ride service- It provides a smooth ride surface as it hardly uses any joints. Compared to concrete pavements it also generates fewer sound emissions. Due to the less wear and tear in a bituminous pavement, the smoothness is maintained.
- Less expensive- The overall maintenance and cost of bitumen paving services are far less than the concrete ones.
Types of Bitumen
Bitumen can be classified into the following categories:
- Penetration grade bitumen: As the name suggests, penetration bitumen goes through penetration tests that characterize the bitumen and makes it hard.
- Oxidized bitumen grades: Processed air is introduced to treat the refinery bitumen further. This process gives rise to oxidized bitumen. The application of oxidized bitumen is mainly confined to industries like coating pipes and roofing.
- Cutback bitumen: The cutback bitumen is a grade of bitumen that aims to reduce the viscosity temporarily. It introduces a volatile oil that reduces the viscosity.
- Bitumen emulsion: Bitumen emulsion is formed when distinct globules of bitumen are released into the continuous form of water. This form of penetration grade bitumen is utilized for laying purposes.
- Polymer Modified Bitumen: Modified
bitumen is developed by the strength modification processes of the
penetration graded bitumen. In this process, a small quantity of polymer
is added. The quantity might vary between 2% to 8%.
All
the above-mentioned points have highlighted the ample number of
advantages that you can expect from bitumen paving services. Bitumen
paving services are used widely in road construction. The majority of
the leftover bitumen pavement materials are recyclable and hence are
recycled at central processing plants. The bituminous pavements are
observed at highways. Bitumen is a result of the incorporation of few
chemicals.
