What was bitumen used for

Pure bitumen is a colloid dispersion of microscopic asphalt particles dispersion phase. The chemical composition of bitumen is a mixture of various hydrocarbons with molecules of oxygen, sulfur, and nitrogen. Hydrocarbons present in bitumen are mostly condensed naphthene and aromatic rings with the small number of side paraffin chains. Bitumen is partially or completely soluble in various organic solvents. Dissolved fractions of bitumen insolvent are called maltenes or petrolenes, and undissolved fractions are called asphaltenes.

The maltenes are a mixture of resins and oil, and they are a dispersing agent. For the most part, the physical properties of bitumen depend on the dispersion degree of asphaltenes in maltenes. Bitumen is generally for industry use. Asphalt was first used for its natural adhesive and waterproofing characteristics, but it was also used as a medicine. It was used to bind building materials together, as well as to line the bottoms of ships.

Herodotus, a fifth-century BC Greek historian, claimed that the walls of ancient Babylon contained bitumen. Asphalt is composed of complex hydrocarbons and contains elements such as calcium, iron, sulfur, and oxygen.

The quality of material and ease of production depends on the source and type of crude oil it is derived from.

The material is used most often in road paving. Most roads in the United States are made of either bitumen or a combination of bitumen and aggregates, such as concrete. Engineers replacing asphalt roads can reuse the material on other road projects. Manufacturers use it in the creation of roofing products due to its waterproofing qualities. Under heavy loads, Asphalt can deform permanently, depending on the composition of the asphalt mixture, the ambient temperature, and the amount of stress places on the material.

Asphalt oxidizes, which can leave the asphalt brittle and result in it cracking. Asphalt is a mixture of dense, sticky, viscous organic liquids, mainly composed of polycyclic aromatic hydrocarbons, naturally occurring or obtained by crude oil distillation. Naturally occurring or crude bitumen is a sticky, tar-like form of petroleum that is so thick and heavy that it must be heated or diluted before it will flow. At room temperature, it is much like cold molasses.

Refined Asphalt is the residual bottom fraction obtained by fractional distillation of crude oil. In Australian English, Bitumen is sometimes used as the generic term for road surfaces. In Canadian English, the word bitumen is used to refer to the vast Canadian deposits of extremely heavy crude oil, while asphalt is used for the oil refinery product used to pave roads and manufacture roof shingles. Diluted Bitumen diluted with Naphtha to make it flow in pipelines is known as dilbit in the Canadian Petroleum industry, while bitumen upgraded to synthetic crude oil is known as syncrude and syncrude blended with bitumen as a syn bit Most bitumens contain sulfur and several heavy metals such as Nickel, Vanadium, Lead, Chromium, Mercury and also Arsenic, Selenium, and other Toxic Elements.

Bitumen can provide good preservation of plants and animal fossils. Bitumen is primarily used for paving roads. Its other uses are Waterproofing Products, including the use of Asphalt in the production of roofing felt and for sealing flat roofs. The different grades produced for suited applications are distinguished by two numbers to indicate the midpoints of their softening point and penetration ranges.

Blown Grade Bitumen is widely used as an anti-slip layer compound in the piling industry, for the manufacturing of sound dampening felts, for the manufacture of roofing felts, for the manufacture of under carriage sealant in the automobile industry, electric cable joint protection, joint filling compound, sealant compound and a multitude of industrial applications.

Fuel oil can be added to the process to increase the penetration if required for custom applications and requirements. Bitumen Emulsion is made up of three basic ingredients which include Bitumen, an emulsifying agent and water.

Based on the various specifications it may contain other additives such as coating improvers, stabilizers, anti-strips or break control agents. It is a well-known fact that asphalt and water will not mix, except under carefully controlled conditions using highly specialized equipment and chemical additives.

Bitumen Application Bitumen Application For civil engineering works Constructions of roads, runways, and platforms. Waterproofing to prevent water seepage. Mastic floorings for factories. Canal lining to prevent erosion. Dump-proof courses for masonry. Tank foundation. Joint filling material Bitumen is widely used in the construction of asphalt roads and bituminous membrane products.

Bitumen is commonly used to build highways, motorways and rail networks. Bitumen has excellent water-proofing properties and is widely used for making roofing products along with a range of other household and industrial applications, from emulsion paints to sound-proofing. Call for your FREE on-site consultation: Dec 16 Production Crude oil is refined through a distillation process that heats up the oil in a large tank and collects the vapors that are produced at varying temperatures.

Melting Point Bitumen has a melting point of around degrees Fahrenheit which is high enough to be safely used for roadway designs and low enough to be heated up without using a large amount of energy. Recycling Because of the low melting point of asphalt bitumen, it is easy to heat the asphalt up as part of an asphalt recycling process. Chemical Composition Asphalt bitumen is non-toxic and is comprised of hydrocarbons and organic material with a high molecular density.

Colored Bitumen Traditional asphalt bitumen is black because of the dense organic material that makes up the material. Author: Lone Star Paving. Related posts.
