Bitumen 10/20

Bitumen Penetration Degree 10/20

Definition of Bitumen Penetration Degree 10/20

Bitumen penetration grade 10/20 represents a type of hard penetration bitumen. To produce it, manufacturers use a vacuum distillation process in oil refineries. This process effectively removes leftover materials from the distillation tower, leading to a bitumen grade that offers significant long-term savings. Specifically, the 10/20 grade allows for thinner pavement designs, which can use up to 30% less asphalt compared to traditional designs. Despite this reduced material usage, it still ensures a long pavement life. As an example, Jay Pasargad exports this grade, making it ideal for various applications such as road construction and repair, as well as asphalt pavement production.

Applications of Bitumen Penetration Grade 10/20

When it comes to applications, bitumen 10/20 proves highly effective in road construction and the repair of asphalt pavements. Moreover, it excels in producing hot mix asphalt for foundations and wearing courses, thereby making it a suitable choice for pavement production. Its unique properties significantly enhance the quality and durability of asphalt surfaces, which ultimately leads to better performance over time.

Uses of Bitumen Grade 10/20

In addition to its applications, bitumen 10/20 finds extensive use in both road construction and repair projects. Due to its strong viscosity compared to other grades, it stands out as particularly effective in hot mix asphalt applications. This high viscosity ensures a stable and cohesive mix, which contributes to the longevity of road surfaces and reduces maintenance needs.

Softening Point and Penetration

Furthermore, Jay Pasargad’s Grade 10/20 10/20 bitumen consists of pure petroleum bitumen produced from a vacuum distillation process that employs hot air. This bitumen derives from crude oil residues after the cracking and removal of hydrocarbons. As a result, the penetration grade falls between 10 and 20 decimillimeters, while the softening point ranges from 58 to 66 degrees Celsius. Notably, this grade exhibits thermoplastic properties similar to synthetic resin, meaning it softens when heated and hardens upon cooling. Consequently, its viscosity remains strong compared to other bitumen grades, which adds to its appeal.

Warranty on Bitumen Quality Grade 10/20

In terms of quality assurance, Jay Pasargad guarantees the quality of its bitumen by coordinating with international inspectors. These inspectors check both the quality and quantity of the bitumen during the loading process onto ships. Additionally, the company ensures production quality through detailed batch test reports before shipment. Importantly, Jay Pasargad’s bitumen complies with ASTM/EN 12591 standards. When compared to unmodified asphalt, this bitumen grade exhibits higher stiffness, viscosity, and resistance to wear.

Properties of Bitumen Grade 10/20

To ensure that the bitumen meets industry standards, Pasargad 10/20G bitumen undergoes rigorous testing by international inspectors. Thus, it carries the guarantee of compliance with ASTM international standards, making it a reliable choice for construction professionals.

Bitumen Specifications: 10/20 vs. 115/15

When comparing packaging, 115/15 bitumen typically comes packaged in 25-kilogram bags, plastic bags, or boxes. In contrast, 10/20 bitumen is packaged in drums or jumbo bags. This difference in packaging reflects the varying applications and handling requirements for each grade.
