Bitumen Penetration Grade 40/50

Bitumen Penetration Grade 40/50 Description

Bitumen penetration grade 40/50 bitumen means the penetration value is in the range 40 to 50 at standard test conditions which commonly used as a Paving Grade. Bitumen is applicable for the production of hot mix asphalt for bases and pavements and for road construction. Penetration Grade Bitumen supplied by HJ Oil is produced through aeration on vacuum bottom (the raw material used for making bitumen left in vacuum distillation column in oil refineries) in bitumen production units. Its penetration grade ( the measure of bitumen hardness) is between 40 to 50. Bitumen is specified by the penetration and softening point test. Designing is by penetration range only. The penetration grade bitumen has a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature-viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability, and application temperatures of bitumen.

The Bitumen mode is dependent on temperature. The temperature-vs-stiffness relationship of bitumen is dependent on the type of crude oil and its refining method. Bitumen penetration grade 40/50 is semi-hard penetration grade bitumen used as a paving grade bitumen which is suitable for road construction and repair. It is also used for the production of asphalt pavements with the technical specification. This grade of bitumen is mainly used in the manufacturing of hot mix asphalt for bases and wearing courses. Bitumen 40/50 is one of the most used bitumen grades and it’s a basic material for all other bituminous products.

Bitumen Penetration Grade 40/50 Applications

Bitumen 40/50 is Suitable for road construction and for the asphalt pavements with superior properties. This type of bitumen used in the manufacture of hot mix asphalt for bases and wearing courses and the main usage of this product is used in the road in tropical regions. the bitumen is provided during the presses of oxidation of vacuum bottom in bitumen production units.

Bitumen Mastic

Bitumen Mastic Definition

Bitumen Mastic is a type of asphalt composed of suitable graded mineral and asphaltic cement, also to take in proper proportion to consistent mass solid or semi-solid form. when it is heated it is in fluid form and then becomes solid.
Mastic asphalt (MA) is a dense mixture consisting of coarse aggregate, and/or sand, and /or limestone fine aggregate, and/or filler and bitumen, which may contain additives (for example polymers, waxes). The mixture is designed to be of low void content. The binder content is so adjusted that the voids are completely filled and that even a slight excess of binder may occur. Mastic asphalt is pour-able and able to be spread in its working temperature condition. It requires no compaction on site.
On the other hand asphalt mastic – abbreviation AM – is a term used in Europe to describe a mix of sand (that is, without aggregates > 2 mm), and/or limestone fine aggregate, and/or filler and bitumen that is used especially for waterproofing in a variety of applications.
The formulation of the mixture is chosen as a function of
– field of application
– mechanical load
– thermal load
– chemical load
– climatological influences.

Bitumen Mastic Applications

Bitumen Mastic is used for concrete and ordinary red brick masonry with cement plaster surface is the basic method for the construction of floors, foundation, tanks, etc. To protect the commercial and civil structure of plants and building from corrosive attack acid-resistant brick lining is mostly used, Bitumen Mastic has good resistance to weak, diluted acids, alkalis salts, etc, also used as open mastic flooring for heavy-duty flooring.
It is used in:
– Bridge decks
– Flooring (building)
– Flooring (industrial)
– Road construction
– Rooftop car parks
– Hydraulic constructions
– Flat roofing
– Tanking

Production Process

In the past, that means approximately until 1970, mastic asphalt was often manufactured in mobile cookers (usually at the worksite) that were filled with the various components. By slowly heating them, the components were brought to the right temperature, where the mix-ing device (then mostly a horizontally rotating mixer shaft) served to make sure that the mix was homogeneous for processing. Of course, in this way, no high production rates could be achieved.
Nowadays mastic asphalt is manufactured in (specially designed) stationary industrial plants. These are designed to proportion the materials, dry the mineral aggregates, and mix them in a heat-controlled environment. Application specifications control the temperatures at which material is produced. Typically, in the past, mastic asphalt production temperatures were in the range of 230 to 270 ºC. However in recent years considerable research and investments have been done (and are still ongoing) to lower these temperatures beneath 230 ºC – in some countries even below 200 °C.

Packing

Bitumen Mastic is available in 25 Kg Carton Box & 20 Kg new steel drum.

Anionic Bitumen Emulsion

Anionic Bitumen Emulsion Description

HJ Oil Group is a supplier of high-quality Anionic Bitumen Emulsion.
The preparation of bitumen emulsion is essentially the grinding of bitumen in water with a surfactant. Therefore, the emulsifier is one of the most important components of bitumen emulsions, which directly influences the quality and characteristics of the product. The emulsifier is a surfactant. By chemical nature, surfactants are divided into several types, depending on the charge of its particles. Since water bitumen emulsions are used intensively as binding and film-forming material in construction, two types of emulsifiers are used: anionic and cationic.

Chemical surface-active agents, which serve as emulsifiers, are classified by the electrochemical charge that is attained when they dissociate in a water solution. In the case of anionic emulsions, the chemical charge is negative. The chemical type and quantity of surface-active agent used in the manufacturing process govern the process in which the resulting asphalt emulsion can be used.

The term Anionic Bitumen Emulsion is derived from the migration of particles of bitumen under an electric field. The droplets migrate toward the anode (positive electrode), and hence the emulsion is called anionic. In an anionic emulsion, there are “billions and billions” of bitumen droplets with the emulsifying agent at the water bitumen interface. The tail portion of the emulsifying agent aligns itself in the bitumen while the positive portion of the head floats around in the water leaving the rest of the head negatively charged and at the surface of the droplet. This imparts a negative charge to all the droplets. Since negatives repel each other, all the droplets repel each other and remain as distinct bitumen drops in suspension. A typical anionic emulsifying agent is shown below along with a diagram showing the orientation of the agent at the bitumen-water interface and the negative charge imparted to each drop.

ANIONIC EMULSION

RS	MS	SS
RS-1 RS-2	MS-1 MS-2 MS-2h HFMS-1 HFMS-2 HFMS-2h HFMS-2s	SS-1 SS-1h

The difference is that the anionic bitumen emulsion is negatively charged, while the cationic emulsions are positively charged. The choice of emulsifier used in the preparation of the emulsions determines the efficiency and reliability of the product.

For certain reasons, cationic systems have a significant advantage over anionic emulsions. Most of the fillers used in road construction have a limited amount of positively charged particles, which can attract the negatively charged particles of the anionic emulsion. Therefore, it is more difficult to create a uniform structure and ensure a high degree of adhesion with an anionic surfactant. When using anionic emulsion, bitumen should be modified by additives, while in the cationic emulsion, the emulsifier itself serves as an adhesion additive.

Unlike cationic emulsions, which readily interact with alkaline and acidic minerals, anionic emulsions are less versatile and work well only with alkaline minerals.
The amount of emulsifier applied influences emulsion breakdown rate, i.e. the time until the bitumen precipitating from the emulsion, returns to its original state.

Cutback Bitumen RC-800

Cutback Bitumen RC-800 Description

Cutback Bitumen RC-800 is Rapid curing (RC) cut-back asphalt consisting of penetration grade asphalt cement and diluent or cutter of rapid volatility.
Our Cutback Bitumen RC-800 complies with cutback petroleum asphalts of the rapid-curing type for use in the construction and treatment of pavements.

Cutback bitumen RC800 is dissolved of bitumen in solvents of Naphtha. Petroleum solvents such as naphtha, kerosene, etc. are cutback agents which can reduce the viscosity of the bitumen. As well as improving the ability to coat aggregates.

Cutback Bitumen RC-800 is a rapid curing cutback bitumen that contains 75% bitumen, is black in color, and is manufactured strictly as per ASTM D 2028M standard. The diluent temporarily reduces the viscosity of the asphalt cement for ease of handling and application. After application, the diluent evaporates, leaving asphalt cement to perform its function. RC–800 bitumen viscosity is between 800-1600 CST.

Cutback Bitumen RC-800 is dissolved of bitumen in solvents of gasoline. In many countries, kerosene and other volatile petroleum-derived products are added as a cutter or cutback agent to bitumen to reduce (or cutback) the viscosity of the bitumen. The mixture obtained may be called cutback bitumen.

gasoline or naphtha is used as the solvent in order to manufacture rapid curing bitumen cutback. RC-800 is one of the examples of a rapid curing cutback bitumen. The typical amount of solvent or distillate in a cutback bitumen is from 12% to 40%. Naphtha is used as a bitumen cutback agent at different concentrations according to local conditions and requirements.

The reduction in viscosity of the bitumen aids the construction of seal coats in road pavements as the softened mixture wets the chips more easily. The cutback agent evaporates from the seal coat, the cutback agent becoming a negligible component of the seal coat a few months after application. If significant amounts of the cutback agent remain in the seal coat an unwanted long term softening effect may result. Also, Cutback asphalt is an asphalt cement that has a solvent or distillate such as gasoline, diesel fuel, kerosene, or naphtha added to make the asphalt liquid at ambient temperatures and improve its ability to coat aggregates.

Cut back bitumen are easy to use because it is cold applied. Cut back grade bitumen is normally used in spraying. The main applications of RC-800 are in road pavement, tack coat, and prime coat.

Oxidized Bitumen

Oxidized Bitumen Description

Blown bitumen grade 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 bitumen 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.

Oxidised bitumen ” Oxidized Bitumen, Oxidized Asphalt ” range is used in the waterproofing industries, for carpet-backing, corrosion protection, acoustic panels and the manufacture of paints, amongst other applications.

Air-blowing: The manufacturing process used to make oxidized roofing asphalts in which air is blown through an asphalt flux. An exothermic oxidation reaction occurs, yielding an asphalt that is harder, more viscous, less volatile, and less temperature-susceptible than the asphalt flux used as the feedstock to the process.

Asphalt, oxidized (blown or air-refined) (CAS number 64742–93–4): Asphalt treated by blowing air through it at elevated temperatures to produce physical properties required for the industrial use of the final product. Oxidized asphalts are used in roofing operations, pipe coating, undersealing for Portland cement concrete pavements, hydraulic applications, membrane envelopes, some paving-grade mixes [AI 1990b], and the manufacture of paints [Speight 1992].

Blowing still: A closed-process vessel fitted at its base with a sparger and used in the air-blowing process to make many types of roofing asphalt.

Coating asphalt: An air-blown or oxidized asphalt used to manufacture roofing materials used in a variety of roofing systems such as asphalt shingles, polymer-modified bitumen roofing, reinforcing and underlayment felts, and roll roofing products.

Modified bitumen: A roofing system based on membranes manufactured by impregnating or coating one or more fabric plies with a straight-run or oxidized asphalt modified using a polymer, usually atactic polypropylene (APP) or styrene-butadiene-styrene (SBS). Modified bitumen systems may be torch-applied or installed by adhesion in hot asphalt or a cold-applied, solvent-based asphalt adhesive (cutback asphalt). Modified bitumen systems are used on low-slope (primarily commercial or industrial) roofs.

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.
