Oxidized Bitumen 85/35

Oxidized Bitumen 85/35 Description

Oxidized Bitumen 85/35 or Oxidized Bitumen is produced by blowing hot air into the penetration bitumen. This action makes the bitumen more rubbery than its original formula and it becomes harder bitumen. This bitumen recovery the weight loss under heating. Due to low thermal sensitivity, the softening point is much higher than regular bitumen and the penetration index (PI) is higher than road construction bitumen (8>PI>2) due to the letter has a gel-like structure because of asphalt accumulation.

Oxidized Bitumen 85/35 is produced by the air-blowing of penetration grade bitumen. This is done at high temperatures, resulting in a material of a much higher penetration index. Bitumen 85/35 is based on petroleum bitumen which is made by blowing bitumen 60/70 by very hot air. The designation of the Blown Asphalt 85/35 refers to the midpoint of the softening point acceptance criteria.

Bitumen 85/35 is produced by either Continuous or Staggered Blowing Process. Heated Penetration Grade Bitumen under controlled environment is blown with air which controls the Oil Content in the Bitumen while it oxidized. The different grades for suited applications produced are designated by two numbers to indicate the mid-points of their softening point and penetration ranges.

As said before, Oxidized Bitumen 85-35 is based on petroleum bitumen which is made by blowing bitumen 60/70 by very hot air. In addition, the numbers relate to the midpoint of the material’s softening point and penetration respectively. The softening point value measured by the Ring and Ball method as determined by ASTM D36. Also, the penetration value is in 1/10 mm as determined by IP49 or ASTM- D5.

Oxidized Bitumen 85/35 Applications

Oxidized Bitumen 85/35 is a solid or semi-black solid material and gradually liquid when heated. Oxidized Bitumen grades are blown or oxidized Asphalt‘s which are produced by passing air through soft bitumen under controlled temperature conditions. This process gives the bitumen more rubbery properties than penetration or hard grade bitumens and a variety of uses in industrial applications.

This bitumen is mostly used in industry, such as roof insulation, flooring, industrial mastic, pipe coating, and paints. Specification of Blown Asphalt is categorized based on softening points and penetration rates. Also, Blown Asphalt 85/35 using as raw material for bitumen coat, roofing, insulation, and isolation bitumen membrane sheet.

Technical Advantages of Blown Asphalt 85/35

• Durability
• Flexibility
• Water-Resistant
• Chemical Stability

Compared to paving grade bitumen:

• Reduced temperature susceptibility
• Exhibits a more ‘solid’ nature at ambient temperatures
• High penetration index

Recommendations for Handling / Storage

The heating of packaged bitumen is a critical phase in most of the final uses. Typically, the packaged material is heated and melted in boilers out on site.

However, control at the heating phase is very important in terms of health and safety as well as in maintaining the quality of the product.

A note must be taken of the maximum safe handling temperature of 230 C and this should not be abused. Bitumen is a poor conductor of heat, consequently, control of the heating phase is of paramount importance.

The Blown Asphalt material should be broken up prior to placement in the boiler. This exposes a larger surface area to the heat and encourages a more even heating regime. Without the larger exposed surface area, aggressive heating at the base and sides of the boiler may well result in localized overheating, altering the characteristics of the RAHA modified bitumen, and potentially causing thermal cracking of the bitumen, creating the release of low lash vapors. The flashpoint of the blown asphalt then becomes irrelevant; as these low flash vapors determine the fire risk.

Melted bitumen should not be left in the boiler and reheated from cold, as there is then a high potential for localized overheating around the heating area (lack of convection means poor heat transfer) and potential development of a pressurized pocket of low flash vapors.

Be aware of the placement of any temperature monitoring or control devices. As a result of the poor thermal conductivity of the bitumen, a thermometer in the bitumen some distance from the heat source could read significantly different (even hundreds of degrees) from the true temperature of the bitumen near the heat source.

Health & Safety

Workers should wear protective masks, gloves, and goggles during application. The asphalt can be removed from equipment and tools with kerosene or gasoline. Care should be taken when heating Blown Asphalt 85/35 to avoid overheating. For Health and Safety information, please make reference to the relevant MSDS.

The Blown Asphalt 85/35 should be heated double temperature against the softening point to be able to have flow and viscosity.

Storage and Handling

The heating of packaged bitumen is a critical phase in most of the final uses. Typically, the packaged material is heated and melted in boilers out on site.

However, control at the heating phase is very important in terms of health and safety as well as in maintaining the quality of the product.

The note must be taken of the maximum safe handling temperature of 230 C and this should not be abused. Bitumen is a poor conductor of heat, consequently, control of the heating phase is of paramount importance.

The Blown Bitumen material should be broken up before placement in the boiler. This exposes a larger surface area to the heat and encourages a more even heating regime. Without the larger exposed surface area, aggressive heating at the base and sides of the boiler may well result in localized overheating, altering the characteristics of the modified bitumen and potentially causing thermal cracking of the bitumen, creating the release of low lash vapors. The flashpoint of the oxidized bitumen then becomes irrelevant; as these low flash vapors determine the fire risk.

Melted bitumen should not be left in the boiler and reheated from cold, as there is then a high potential for localized overheating around the heating area (lack of convection means poor heat transfer) and potential development of a pressurized pocket of low flash vapors.

Be aware of the placement of any temperature monitoring or control devices. As a result of the poor thermal conductivity of the bitumen, a thermometer in the bitumen some distance from the heat source could read significantly different (even hundreds of degrees) from the true temperature of the bitumen near the heat source.

Bitumen

Bitumen Definition

Bitumen, also known as asphalt in the United States, is a substance that forms through the distillation of crude oil. It has waterproofing and adhesive properties. Bitumen production through distillation removes lighter crude oil components, such as gasoline and diesel, leaving the “heavier” Asphalt behind. The producer often refines it several times to improve its grade. Bitumen can also occur in nature: Deposits of naturally occurring bitumen form at the bottom of ancient lakes, where prehistoric organisms have since decayed and have been subjected to heat and pressure.

Bitumen is viscous, nonvolatile liquid or solid. Asphalt is a complex colloid system the chemical properties of which are dependent on the properties of crude oil from which it is produced. Pure bitumen is a colloid dispersion of microscopic asphalt particles (dispersion phase). The chemical composition of Asphalt 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. Mass fraction of hydrocarbons is 75-85%, hydrogen 9-10%, oxygen 2-8%, sulphur 5-7%, and nitrogen 0.1-0.5%. Bitumen is partially or completely soluble in various organic solvents. Dissolved fractions of Asphalt 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.

Properties of Asphalt

– Adhesion: Bitumen has the ability to adhere to a solid surface in a fluid state depending on the nature of the surface. The presence of water on the surface will prevent adhesion.

– Resistance to Water: Bitumen is water-resistant. Under some conditions, water may be absorbed by minute quantities of inorganic salts in the bitumen or filler in it.

– Hardness: To measure the hardness of bitumen, the penetration test is conducted, which measures the depth of penetration in tenths of mm. of a weighted needle in bitumen after a given time, at a known temperature. Commonly a weight of 100 gm is applied for 5 sec at a temperature of 77 °F. The penetration is a measure of hardness. Typical results are 10 for hard coating asphalt, 15 to 40 for roofing asphalt and up to 100 or more for waterproofing bitumen.

– Viscosity and Flow: The viscous or flow properties of bitumen are of importance both at high temperature during processing and application and at low temperature to which bitumen is subjected during service. The flow properties of bitumen vary considerably with temperature and stress conditions. Deterioration, or loss of the desirable properties of bitumen, takes the form of hardening. Resultantly, a decrease in adhesive and flow properties and an increase in the softening point temperature and coefficient of thermal expansion.

– Softening point: Softening point is the temperature at which a steel ball falls a known distance through the bitumen when the test assembly is heated at a known rate. Usually, the test consist of a (3/8)in dia steel ball, weigh 3.5 gm, which is allowed to sink through a (5/8) in dia, (1/4) in the thick disk of bitumen in a brass ring. The whole assembly is heated at a rate of 9 °F per min. Typical values would be 240 °F for coating grade asphalts, 140 °F to 220 °F for roofing asphalt and down to 115 °F for bituminous waterproofing material.

– Ductility: The ductility test is conducted to determine the amount bitumen will stretch at a temperature below its softening point. A briquette having a cross-sectional area of 1 in2 is placed in a tester at 77 °F. Ductility values range from 0 to over 150 depending on the type of bitumen.

Bitumen Applications

The major bitumen produced in Middle East and the world known as Asphaltum is used in road construction. In road construction, It is used as a bonding agent for asphalt, and the use of it in the construction industry is ranked second as insulation. Estimates show that the annual amount of Egyptian bitumen in the world is about 102 million tons. Of this, about 85 percent of the Asphaltum is used in the road construction industry, and the 60/70 bitumen is most used. More than 10% of the bitumen produced in the world is used in the building industry and as insulation. And seagulls are used as sealing, insulating, pipe coating, etc.

Types of Bitumen By Grade

There are different types of asphalt cement available with different properties, specifications and uses based on requirements of consuming industry.

Oxidized Grade
Blown bitumen grades or Oxidized Bitumen are produced by passing air through the penetration grades. This process gives the bitumen more rubbery properties than its original formula and they are simply harder bitumen. Hard asphalt under controlled temperature conditions is widely used as an anti-slip layer compound in the piling industry, for manufacture of roofing felts, the roofing and waterproofing industries, for sound dampening felts and under carriage sealant in the automotive industry, electric cable joint protection, joint filling compound, sealant compound and many others. Also used in sealing saw cuts and joints where expected movements are minimum. It is also used in the manufacturing of bituminous marine mastic for the oil & gas pipeline joints.

Penetration Grade
Graded Bitumen is classified by the depth to which a standard needle will penetrate under specified test conditions. This “pen” test classification is used to indicate the hardness of bitumen, lower penetration indicating a harder bitumen. Specifications for penetration graded bitumens normally state the penetration range for a grade, e.g. 50/70. Other tests are used to classify the bitumen for specification purposes, such as softening point, solubility, flash point etc.

Performance Grade
Performance Grade (PG) bitumen is Asphaltum which is graded based on its performance at different temperatures. The Long-Term Pavement Performance(LTPP) has given certain algorithm to calculate the temperature of the pavement based on the temperature of the air above. From this, the highest and the lowest temperatures of the pavement is calculated and the bitumen that performs well in that temperature range is selected.

Viscosity Grade
Viscosity Grade Bitumen (Asphalt) is a standard grade Asphaltum usually used as a Paving Grade Bitumen suitable for road construction and for the production of asphalt pavements with superior properties. This grade of Asphaltum is mainly used in the manufacture of hot mix asphalt for bases and wearing courses, and possesses characteristics and qualities unique sand quite different from other agents. They achieve very flexible and tenacious connections with other materials due mainly to viscoelastic response of Asphaltum, which behaviour depends on how fast charges are applied.

Polymer Modified
Polymer modified bitumen (PMB) is one of the specially designed and engineered Asphaltum grades that are used in making pavement, roads for heavy duty traffic and home roofing solutions to withstand extreme weather conditions. PMB is a normal bitumen with the added polymer, which gives it extra strength, high cohesiveness and resistance to fatigue, stripping and deformations, making it a favorable material for infrastructure.

Other Types of Bitumen

Cutback Bitumen
Cutback or Liquid Bitumen is asphaltum that is dissolved in a solvent. Typical solvents include Naphtha, gasoline and kerosene, white spirit etc. The type of solvent controls the curing time while the amount determines the viscosity of the Cutback Bitumen. Bitumen is ‘cutback’ by adding controlled amounts of petroleum distillates such as kerosene. This is done to reduce the viscosity of the asphaltum temporarily so it can penetrate pavements more effectively or to allow spraying at temperatures that are too cold for successful sprayed sealing with neat Asphaltum. The materials used to cutback bitumen will evaporate after application to leave the remaining material similar in hardness to the original asphaltum.

Blown Bitumen
It comes from hot air blown to pure asphaltum in the last stage of refining. In this process, hot air having 200-300 degree centigrade temperature is blown to bitumen container with porous tubes. In this process, hydrogen atoms in Asphaltum hydrocarbon are combined with oxygen in the air and by forming water, polymerization happens. Compared with pure Asphaltum, blown asphalt has a low penetration rate and a high softness point. This kind is used in making roof sheets, automobile battery, and coating.

Natural Bitumen
Natural bitumen or native asphalts are a class of Asphaltum which have been naturally produced due to climate conditions in the course of time, and are used without the need to be processed in distillation ways; they are very varied regarding their composition and properties.

Coating Bitumen
Bitumen coating compositions having substantially improved application and drying properties and producing coatings of improved properties including resistance to ultraviolet rays and alligatoring resulting therefrom said coating compositions comprising volatile solvent solutions of a bitumen coating material having softening point between 110 F To 250 F. The bitumen coating are also characteristically non-viscous materials which are not thixotropic and are therefore ordinarily applied as thin films. It’s compositions may also contain filler materials which tend to settle from the non-thixotropic compositions after storage for only a short time. It has been proposed in the past to add inert colloidal fillers such as silica to obtain thixotropic properties and thicker films on the application of the compositions. However, even such inert fillers tend to affect only solution properties and generally exist in the finished coating as an expensive additive which does not benefit other properties of the coating.

Bitumen Emulsion
This is a mixture of water & asphaltum. Hey wait, we know that asphaltum is a oil product and it cannot be mixed with water. That is why we add an emulsifier (a surface active agent) with water before adding asphaltum. Addition of emulsifier with water facilitates breaking of asphaltum into minute particles and keeps it dispersed in suspension.Therefore we can say that a bitumen emulsion is a liquid product consisting of three things, (i.e. water + Emulsion + Asphaltum) where droplets of asphaltum are suspended in water.
