Penetration bitumen grade 60/70 is a moderate type of bitumen in terms of hardness, meaning it is not whether too hard nor too soft. Therefore, this grade of penetration bitumen resists temperature changes from -22 to +76. Accordingly, it is a perfect choice for road engineers in various regions, particularly Asia and South-East Africa.The specifications and test results will indicate which type is proper for a specific country and climate. For example, bitumen penetration grade 60/70, 80/100, and cutback MC 30 all have a high demand in India. Most of the Indian construction companies apply …

Different types of Bitumen: Penetration Grade Bitumen. Penetration Grade Bitumen is refinery bitumen, which is composed of different viscosity recognized as Petroleum Grade Bitumen. The penetration test is performed to identify the Bitumen, based on the hardness. This type is a standard bitumen regularly applied as a Paving Grade necessary for ...Bitumen is available in the market in various grades. The suitable grade of bitumen is selected as per the surfacing type and climatic conditions as well. The grading of the bitumen is done on the basis of the consistency of bitumen. The consistency, in turn, is measured by the penetration value obtained from the penetration test of the bitumen.

Bitumen types. Bitumen types. Bitumen has a number of applications but its use for construction and maintenance of roads either directly or through asphalt accounts for nearly 90 % of all demand. Key bitumen types for road applications including paving grades, cutback bitumen, and bitumen emulsions.Traditionally bitumen is regarded as a colloidal system which consist of high molecular weight asphaltene micelles & are dissolved in lower molecular weight oily medium called as maltenes. According to structure bitumen can be classified in two type :-1) SOL Type or solution type. 2) GEL Type or gelatinous type.

Answer (1 of 2): There are different methods of grading of bitumen such as chewing, penetration grading, viscosity grading and superpave performance grading of bitumen. Following are the different methods used for grading of bitumen 1. Grading by chewing 2. Penetration grading 3. Viscosity grad...Bitumen Emulsion. Bitumen emulsion is a liquefied type of bitumen with a low viscosity. By dispersing bitumen in water and adding an emulsifier, ordinary bitumen turns into a low viscosity liquid that can easily be used in a variety of applications, including repairing …

asphalt in the zero grade (40 per cent in SC-0) while in grade five there is more than 80 per cent. The fluidity or viscosity of each grade is essentially the same regardless of the solvent used (cutback type). In selecting a grade for a given use, it is desirable to select the grade120-150. Softest Bitumen Grade 200-300. The penetration grading system is 100 years old bitumen grading method. In India, before 2006, the most widely used grade of …

Second: Saudi Arabia & types of bitumen. In fact, the second-largest oil producer in the world is Saudi Arabia, which produces 11.81 million barrels of oil per day. Before the United States became an oil superpower in the world, Saudi Arabia was the world's largest oil producer and held the position. for over a …Also, read: What Is Flooring | Types of Flooring. #6. Residual Bitumen: It consists of bitumen thinner and suitable filler made into a plastic Conn. As it is plastic, it can be used for filling cracks in masonry, stopping leakages, etc. Use of Bitumen. Bitumen is used for the manufacture of …

Cutback Bitumen Cutback Bitumen or as it is called Liquid Bitumen, is a kind of Bitumen that is dissolved in a solvent . Typical solvents including 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. packing : 220, 230, 240 Liter DrumAsphalt Binder "A dark brown to black cementatious material in which the predominating ...

III. Largely rely on the atmospheric condition and type of erection, bitumen of various penetration grade is used. Normally used grades are enlisted here, such as 30/40, 60/70 and 80/100. IV. Generally, in hot areas, minor penetration values are considered and in colder areas bitumen with upper penetration values are choose.3 types of bitumen commonly used in the base course We have three types of solid bitumen, which are mostly used in the road construction in the base course. We have briefly discussed them below: Viscosity grade bitumen. Viscosity grade bitumen 10 and viscosity grade bitumen 20 are suitable for road construction in cold regions.

1. Hot Mix Asphalt (HMA) Of all the different types of asphalt out there, hot mix asphalt is currently the most common form used for roads and pavements. It is a flexible mixture of both fine and coarse aggregate and an asphalt binder, resulting in a pavement that is …Bitumen types depend on the volatility of oil substances in bitumen. A small amount of volatile oil substances makes bitumen harder and more brittle. Bitumen has multiple uses (road construction, isolation mate-rial), so it is very important for bitumen to have good adhesivity, i.e., to adhere very well to stone, metal, wood, paper, and other ...

Application of bitumen penetration grade 60/70. Bitumen 60/70 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 mild regions.Slow Curing Bitumen (SC): Cut with a low volatile solvent such as low viscosity oil. and it is classified into 4 grade a) SC 70, b) SC 250, c) SC 800, and d) SC 3000. It is mainly used in cold mix and patching work. 1. As the solvent evaporates into the atmosphere which is a costly affair.

The time of setting depends upon the grade of bitumen. The viscosity of bituminous emulsions can be measured as per IS: 8887-1995. Three types of bituminous emulsions are available, which are Rapid setting (RS), Medium setting (MS), and Slow setting (SC). Bitumen emulsions are ideal binders for hill road construction.Viscosity Grade Bitumen is petroleum grade bitumen, which produced from fractional vacuum bottom which comes from distillation of crude oil, which feasible appliance and behavior changes according to its temperature.
