Admin Which product is used for construction of road?
Option 2 is the correct answer: Bitumen is used for the construction of roads. Bitumen is a mixture of 500-700 organic compounds (hydrocarbons) in which also contain small proportions of Nitrogen, Sulphur and Oxygen. It is a byproduct obtained during the distillation of petroleum.
Which petroleum product is used for road construction?
Bitumen
a) Asphalt also known as Bitumen is the petroleum product used for surfacing roads.
What can be used to make roads?
The most common materials used for paving roads are asphalt and concrete. Factors such as cost and amount of traffic will determine which material is used. Asphalt uses an oil-based substance called bitumen to make sand and crushed rock stick together like glue.
Which mixture is best used for road construction?
When it is used for pavements and road construction it comes in the form of a composite material, asphalt concrete. Asphalt concrete is about 70% asphalt and 30% aggregate particles. Asphalt is one of the most commonly used materials for road construction for a number of reasons.
Is oil used to make roads?
Road Oil is any heavy petroleum oil, including residual asphaltic oil used as a dust palliative and surface treatment on roads and highways. It is generally produced in six grades, from 0, the most liquid, to 5, the most viscous.
Which byproduct of coal is used to make road surfaces?
These days, bitumen, a petroleum product, is used in place of coal-tar for metalling the roads. When heated in air, coal burns and produces mainly carbon dioxide gas.
What is the material used in road?
Bitumen, asphalt. A heavy fraction from oil distillation. In North America, this material is commonly known as “asphalt cement,” or “asphalt.” Elsewhere, “asphalt” is the term used for a mixture of small stones, sand, filler, and bitumen, which is used as a road paving or roofing material.
What are the main materials used in construction of a flexible road?
Flexible pavements are constructed using bituminous materials. These can be either in the form of surface treatments (such as bituminous surface treatments generally found on low volume roads) or, asphalt concrete surface courses (generally used on high volume roads such as national highways).
