bitumen is one of the most used materials in road construction along with asphalt. In fact, it is an additive to the asphalt mix.

It’s a quite technical issue to understand how much bitumen is used with asphalt mix but the amount of asphalt needed to pave roads can be calculated. Approximately the typical amount of bitumen used in the construction of roads is between 3.5 and 5 percent. Therefore, the first thing to look for is how much bitumen is contained in the asphalt mixture; after that, the size of the road should be determined. For example, for calculating the volume of bitumen in 1 kilometer of road, the width and thickness are needed. The amount of asphalt binder is determined by taking the difference in mass between both the initial mass of the hot mix asphalt and the volume of the residual aggregate, multiplying that difference by the correction factor, and then taking the moisture content into account. The amount of asphalt binder is typically expressed as a percentage of the mass of the mix that is free of moisture. The amount of bitumen required for a given carpet varies according to its thickness. If by 1 kilometer you mean 1 linear kilometer of road, then you need to provide additional details. For instance, for 1 kilometer with a carpeting thickness of 20 millimeters, you need 10 metric tons of bitumen for a road that is 3.75 meters wide. This includes a surface coat, a wearing coat, and a seal coat. Actually, the asphalt that we drive on is held together by a liquid called bitumen. Asphalt is frequently referred to as bitumen, which is an incorrect term to use. A layer of bitumen is sprayed onto the surface of a bitumen-sealed road, which is then covered with an aggregate. When compared to a bitumen-sealed road, an asphalt road surface produced by asphalt is more durable and has a smoother appearance. Macerals, specifically vitrinite and liptinite, make up the bulk of its composition. The amount of carbon found in bituminous coal ranges from about 45 to 86%, and the remaining 45–86% is made up of water, air, hydrogen, and sulfur that has not been driven off from the macerals.

Bitumen asphalt is a viscous organic substance created as a byproduct of crude oil processing. Because it is easy to manufacture, reusable, non-toxic, and effective as a binder, it is commonly used in the construction of roads. The refining of crude oil involves a process known as distillation, which entails heating the oil in a huge tank and collecting the vapors created at various temperatures during the process. Crude oil contains a high concentration of hydrocarbons, which are known for their high propensity to burn. Hydrocarbons are a type of organic compound created when hydrogen and carbon establish a covalent connection. Diesel, gasoline, and a variety of other high-octane fuels are among the most significant byproducts of crude oil refining. Tar mixture is what remains after crude oil has been refined to extract, among other items, fuels, motor oils, and solvents. The distillation process yields a tar mixture consists of residual hydrocarbons and a considerable amount of organic material in the form of bitumen. The solution is further processed to generate bitumen, which is used in the construction of roadways, as well as various compounds that are included into building materials such as roofing shingles, flashing, and sealants. Bitumen's melting point is roughly 240 degrees Fahrenheit, which is high enough for it to be used safely in the construction of roads and low enough for it to be heated without requiring a great deal of additional energy. In some places of the world, the temperature can increase to a degree where the substance becomes viscous. However, because roads are constructed with layers of aggregate rock, they can survive high temperatures without deforming. 
As a result of the asphalt bitumen's low melting point, it is simple to heat it up as part of the asphalt recycling process. This is required for the procedure. Instead of being deposited in a landfill, the asphalt that is taken from older roadways and transferred to a processing factory will be repurposed. At the asphalt plant, the ripped-up asphalt will be pulverized into a mixture that is easy to measure; this mixture can then be incorporated into recycled roadway mix designs. To make a new asphalt material with the same level of durability as the previous one, older asphalt is blended with bitumen and aggregate rock from more recent times. Bitumen asphalt is composed of organic and hydrocarbon molecules with a high molecular density and is non-toxic. These hydrocarbons become sticky at low temperatures and create strong connections with solid surfaces they come into touch with. As a result of the decomposition of organic carbon material, crude oil deposits are formed. The organic life and plant stuff that existed during the ancient and Jurassic periods gave rise to today's oil deposits. The construction industry makes use of the bitumen that has been refined the most. The primary applications for which it is useful are in the fields of paving and roofing. Asphalt, which is used for roads, runways, parking lots, and footpaths, uses up 85 percent of the world's total bitumen supply as a binder. In the final step, the residue is put through a vacuum distillation column and subjected to additional distillation. This yields bitumen. The term "straight run bitumen" refers to this particular kind of bitumen. The amount of volatile material that is left in the distilled bitumen determines the grade of the bitumen. A product that is less pure and has a higher liquid content will have more volatile material in it.
