Petra Oil

  Bitumen is a highly viscous and dense form of petroleum that is produced from crude oil. It is typically found in natural deposits or obtained as a by-product of the refining process. The production of bitumen from crude oil involves several steps, which are as follows: Extraction: The first step in the production of bitumen is the extraction of crude oil from the ground. This is typically done using drilling rigs and other equipment, and the crude oil is usually extracted from deep underground reservoirs. Separation: Once the crude oil is extracted, it is transported to a refinery where it is processed to separate the different components. This involves heating the crude oil and passing it through a series of distillation columns, where the lighter components are separated from the heavier ones. Upgrading: After separation, the heavy components of the crude oil, including bitumen, are further processed through a process called upgrading. This involves breaking down the heavy mol

  "60/70 grade" is a term commonly used in construction and engineering to refer to the strength of a material, typically concrete or asphalt. In this context, the "60" refers to the compressive strength of the material in pounds per square inch (psi) after 28 days of curing, while the "70" refers to the tensile strength of the material in psi. So, a 60/70 grade material would have a compressive strength of 60,000 psi and a tensile strength of 70,000 psi. These values are commonly used as standards to assess the quality of concrete and asphalt and to determine if they are suitable for use in a particular construction project.

             Bitumen and coal tar are both used as binding agents in the construction of roads and roofs, but they differ in their composition and properties. Bitumen is a naturally occurring mixture of hydrocarbons that is obtained from crude oil or natural deposits. It is a highly viscous, black, or dark brown substance that is used for its waterproofing, adhesive, and insulation properties. Bitumen is also a more sustainable and environmentally friendly option compared to coal tar, as it is derived from a renewable source. Coal tar, on the other hand, is a by-product of the distillation of coal and is known for its high levels of polycyclic aromatic hydrocarbons (PAHs), which are carcinogenic and harmful to the environment. In addition, coal tar is also more difficult to process and produce compared to bitumen, which makes it less economically viable as a construction material. Therefore, bitumen is preferred over coal tar in modern construction due to its superior performance

               In hot climates, grades of bitumen that are typicallyused include: ·          60/70 grade bitumen: This grade of bitumen is commonly used in paving applications and is suitable for climates with high temperatures and high humidity levels. ·          80/100-grade bitumen: This grade of bitumen is suitable for high-temperature applications and is commonly used in the construction of airports and other heavy-duty pavements. ·          85/100-grade bitumen: This grade of bitumen is ideal for hot climates as it has a high softening point and good resistance to thermal cracking. It's worth noting that the choice of the appropriate grade of bitumen depends on several factors including the local climate conditions, the type of pavement, and the traffic volume and loading conditions. 

                                               How much bitumen is needed for a 10km Road?   The amount of bitumen needed to build a 10 km road varies on a number of variables, including the road's width and thickness, the style of pavement (flexible or rigid), the climate in the area, the subgrade conditions, and the kind of traffic the road will handle. According to a rough calculation, flexible pavements may need 3–4 kg of bitumen per square meter of road surface, but rigid pavements may need 5–6 kg per square meter. According to this calculation, the total amount of bitumen needed for a 10 km road with a width of 7 meters and a thickness of 150 mm (0.15 meters) would be roughly: (10,000 m) x (7 m) x (0.15 m) x (4 kg/m^2) = 4,200 kg Note that this is a rough estimate and actual requirements may vary.
