Difference between asphalt asphalt and bitumen

Asphalt asphalt versus bitumen

Indeed, three extremely popular building materials, asphalt, bitumen, and asphalt are difficult to distinguish from one another. However, the nature of these three materials varies drastically, so it is very necessary to distinguish them from one another.

What is asphalt?

Asphalt, or asphalt concrete, a composite material used in construction, is mainly used for paving the pavement. Asphalt is also increasingly being used as the core of dams. Asphalt concrete, consisting of bitumen, a liquid or semi-solid form of black, sticky and viscous material that acts as a binder for mineral aggregates such as sand and rock, is sometimes referred to as asphalt, or band aid.

There are several ways to mix asphalt and aggregates, creating different types of mixes. These include hot mixed asphalt concrete, cut asphalt concrete, warm mixed asphalt concrete, mastic asphalt concrete or sheet asphalt and natural asphalt concrete. Different types of asphalt concrete have different properties, responding to durability, tire wear, braking and road noise and other factors in a unique way for each mix. The Hot mix asphalt concrete is made by heating the asphalt binder to reduce its viscosity. The Warm mix asphalt concrete uses waxes, emulations or even water for asphalt binding, which allows for faster surface availability and is often used for construction sites with tight schedules. The Cold mix asphalt concrete is made by emulsifying the asphalt with soap and water, which reduces the viscosity of the mixture before adding it to the aggregate. This is essentially used on less traveled roads or as a touch up material. The Cut back asphalt concrete is made by dissolving the binder in kerosene or another lighter fraction of petroleum Sheet asphalt or mastic asphalt concrete is made by heating hard quality in a green cooker until it becomes liquid and then adding to the aggregates. Asphalt concrete is also 100% recyclable and therefore 100% environmentally friendly.

What is bitumen?

Bitumen, sometimes called asphalt, is a semi-solid or liquid form of petroleum that is black sticky and naturally highly viscous. Bitumen is found in natural deposits and is used as an adhesive that binds the aggregate particles together into a solid base. While asphalt is mainly used in road construction, it is also used for bituminous waterproofing products, for the manufacture of roofing felt and for waterproofing flat roofs.

Naturally occurring asphalt / bitumen is more commonly referred to as "raw bitumen" and most of the bitumen used commercially is obtained from petroleum. However, bitumen is also found in the remains of ancient microscopic algae and in places where life once remained. These were usually deposited in the mud at the bottom of the lakes or in the ocean where the organisms once lived. Under the pressure of deep burial and a temperature above 50 ° C, the remains are usually converted into bitumen, petroleum or kerogen. A good example of this is La Brea Tar Pits.

In modern times, bitumen is mainly used in asphalt concrete, which in turn is used for road paving. Bitumen is also used to make Japan Black, a paint that is best known for iron and steel.

What is asphalt?

Short for Asphalt jam, Asphalt is a road surface patented by Edgar Purnell Hooley in 1901. The history of asphalt dates back to the 8th century AD when it was found that the streets of Baghdad were paved with asphalt. However, it was more than 1,000 years later that John Loudon McAdam introduced a road construction method called macadamization, which made it possible for horses and carriages or coaches to travel the roads comfortably. However, these roads were found to be quite dusty and easily experienced erosion in heavy rain and later did not support the transportation of heavy motor vehicles. In 1834, John Henry Cassell patented a method of stabilizing macadam roads with tar called "Pitch Macadam". This method involves spreading tar on the surface and applying a typical macadam layer on top of macadam with a mixture of sand and tar. However, the 1901 patent for asphalt that came later required that the tar, modified with small amounts of portland cement, pitch, and resin, be mechanically mixed before being laid down and then compacted with a steam roller.

What is the difference between asphalt and bitumen and asphalt?

• Asphalt and bitumen refer to the same black, sticky semi-solid or liquid substance made from crude oil.

• If used regularly, asphalt can also be used as an abbreviation for asphalt concrete, a popular construction compound made from bitumen and mineral aggregates.

• Although asphalt is widely used for asphalt concrete in the UK, asphalt is a stand-alone method of stabilizing macadam roads with tar.
