Intro

Bitumen 35/50 is a specific grade of bitumen, also known as asphalt, characterized by its penetration value, which ranges between 35 and 50 millimeters. This grading indicates its hardness and consistency, making it a medium-hard bitumen ideal for various paving and construction applications. Derived from the distillation of crude oil, Bitumen 35/50 is a crucial material in the construction industry, particularly for road surfacing and roofing. Its properties, such as durability, water resistance, and adhesive strength, contribute to the longevity and performance of structures and surfaces where it is applied. The specific grade ensures optimal performance in moderate to heavy traffic conditions, making it a preferred choice for highways, airport runways, and other high-stress infrastructure projects.

Description of Bitumen 35/50

bitumen 35/50 is made by vacuum aerating a distillation tower, and its permeability ranges anywhere from 35 to 50. Its name comes from the fact that its permeability can fall anywhere in that range. The manufacturing of liquid bitumen, the insulation business, and the building construction sector are the three industries that make the most frequent use of this kind of bitumen.

The usage of bitumen 35/50 is at its most effective in climates that are subtropical as well as highly arid. This fractional-vacuum-destination crude oil is used as the beginning material in producing petroleum-grade bitumen, which is then refined into the desired product. The vacuum residual feedstock is used in the manufacturing process to produce the bitumen penetration grade 35/50 that is provided by

The penetration test is the basis for deriving the definition of the bitumen grade known as the penetration grade. Only the penetration range is used to derive the designation. The depth to which a standard-loaded needle would vertically penetrate in five seconds in a sample of bitumen kept at a temperature of 25 degrees Celsius is used to assess penetration, which defines the hardness of bitumen. This depth can be found by taking the average of the depths to which the needle would vertically penetrate in each of the five seconds.

Properties of Bitumen 35/50

Penetration grade Bitumen 35/50 is pure petroleum-grade bitumen, manufactured from a vacuum bottom by passing hot air. The bitumen is produced from the remains of crude oil after cracking and removing hydrocarbon. Penetration grade bitumen 35/50 has penetration between 35~50 desi-millimeter and the softening point between 50~ 58 C.

The penetration grade bitumen 35/50 has a thermoplastic property which is like synthetic resin material which gets softer with heating and hardens when cooled. Penetration grade bitumen are specified by the penetration and softening point test. The temperature-vs-stiffness relationship of bitumen is dependent on the source of crude oil and the method of refining.

Bitumen penetration grade 35/50 is hard penetration grade bitumen used as paving grade bitumen suitable for road construction and repair and also for the production of asphalt pavements with below technical specifications.

The Capability of Bitumen 35/50

Bitumen 35/50 boasts a range of capabilities that make it a versatile and reliable material in the construction industry. Its penetration value, which falls between 35 and 50 millimeters, indicates a medium-hard consistency, balancing flexibility and durability. This specific grade of bitumen is particularly suited for applications that demand resilience under moderate to heavy traffic conditions.

Usages of  Bitumen 35/50

Penetration Grade Bitumen 35/50 is a commonly used grade of bitumen in the construction industry and has a wide range of applications. Some of the primary uses of Penetration Grade Bitumen 35/50 include:

• Road construction: Bitumen Penetration Grade  35/50 is used as a binder in asphalt mixtures for road construction. It provides the necessary adhesive properties to hold the aggregate materials together and forms a durable and stable pavement surface.
• Waterproofing: Bitumen Penetration Grade  35/50 is used in the construction of roofing materials, waterproofing membranes, and other protective coatings to provide water resistance and prevent leakage.
• Pavement preservation: Penetration Grade Bitumen 35/50 is also used as a sealant and binder for pavement preservation applications, such as crack sealing and chip sealing, to extend the service life of existing pavements.
• Industrial applications: Penetration Grade Bitumen 35/50 is used in the manufacturing of insulation materials, such as roofing felt and sound insulation products.
• Marine construction: Penetration-grade bitumen 35/50 is used in marine construction as a waterproofing material for seawalls, jetties, and other coastal structures.
• Airport runways: Penetration Grade Bitumen 35/50 is used in the construction of airport runways and taxiways due to its excellent durability and resistance to deformation under heavy traffic loads.

Bitumen 35/50 Advantages and Disadantges

Advantages:

• One of its primary benefits is its exceptional durability and resistance to deformation. The low penetration value of 35/50 dmm at 25°C indicates a high level of hardness, which translates to improved resistance against rutting and permanent deformation under heavy traffic loads.
• Another significant advantage of Bitumen 35/50 is its superior temperature stability. This grade of bitumen maintains its properties across a wide range of temperatures, making it ideal for use in regions with extreme climatic conditions.
• Bitumen 35/50 also exhibits excellent fatigue resistance, which is crucial for pavements subjected to repeated loading cycles. Its high stiffness helps distribute loads more effectively, reducing the stress on underlying layers and minimizing the accumulation of permanent deformation over time. This property is particularly beneficial for highways, airports, and industrial areas where the pavement is subjected to continuous and heavy traffic loads.

Disadvantages:

• One of the primary disadvantages is its higher initial cost compared to softer grades of bitumen. The specialized production process and the higher quality of Bitumen 35/50 contribute to its increased price point.
• The high stiffness that provides excellent durability also makes it more challenging to handle and place during construction. It requires higher mixing and compaction temperatures, which can lead to increased energy consumption and potentially higher emissions during the construction process.
