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.

APP Modified Bitumen Roll Sheet
APP Modified Bitumen Roll Sheet Description
APP Modified Bitumen Roll Sheet is a plastic bitumen blend, which is modified using plastic in the form of atactic polypropylene (APP). As installers begin to torch-apply APP, this type of plastic begins to melt at a point of 300F, where it melts into a liquid wax-like substance that acts as an almost free-flowing liquid which can then be mopped across a surface. APP has a high-temperature tolerance when heating, so is more user-friendly for installers.
This ease of melting makes APP bitumen popular on smaller roofs such as residential properties and commercial flat roofs.

Viscosity Grade Bitumen 40
Viscosity Grade Bitumen 40 Description
Viscosity Grade Bitumen 40 is categorized according to Viscosity (degree of fluidity) grading. The higher the grade, the stiffer the Bitumen. In Viscosity Grade, Viscosity tests are conducted at 60°C and 135°C, which represents the temperature of the road surface during summer and mixing temperature respectively. The penetration at 25°C, which is the annual average pavement temperature, has been also retained in Specifications.
Viscosity Grade Bitumen 40 is used in highly stressed areas such as intersections, near toll booths, and truck parking lots in lieu of old 30/40 Penetration grade. Due to its higher viscosity, stiffer Bitumen mixes can be produced to improve resistance to shoving and other problems associated with higher temperatures and heavy traffic loads.

Viscosity Grade Bitumen 10 Description
Viscosity grade 10 of bitumens are categorized according to Viscosity (degree of fluidity) grading. The higher the grade, the stiffer the Bitumen. In Viscosity Grade, Viscosity tests are conducted at 60°C and 135°C, which represents the temperature of the road surface during summer and mixing temperature respectively. The penetration at 25°C, which is the annual average pavement temperature, has been also retained in Specifications. Viscosity Grade Bitumen 10 is mostly used in spraying applications such as paving in cold regions. VG 10 is an alternative for bitumen 80/100 penetration grade. It also acts as a feedstock in manufacturing Bitumen Emulsion and Modified Bitumen products.
Viscosity grade of bitumen can be done on original (as-supplied) asphalt binder samples (called AC grading) or aged residue samples (called AR grading). The AR viscosity test is based on the viscosity of aged residue from the rolling thin film oven test. With AC grading, the asphalt binder is characterized by the properties it possesses before it undergoes the HMA manufacturing process. The AR grading system is an attempt to simulate asphalt binder properties after it undergoes a typical HMA manufacturing process and thus, it should be more representative of how asphalt binder behaves in HMA pavements. Table 1 lists key advantages and disadvantages of the viscosity grading system.
