1. Introduction
Bitumen is a viscous, black, and sticky substance that is derived from crude oil during the refining process. It is a vital component in road construction, providing durability and strength to the pavement. Bitumen penetration grades are categorized based on their hardness and are commonly used for various applications in the construction industry. In this article, we will dive into the specifics of Bitumen 100/120, one of the popular penetration grades.
2. What is Bitumen 100/120?
Bitumen 100/120, also known as penetration-grade bitumen, is a semi-hard bitumen that falls within a specific range of hardness. It is produced through the refining of crude oil, where the bitumen is extracted and processed to obtain the desired properties. The manufacturing process involves the oxidation of vacuum bottom residue in vacuum oil refineries. This process results in the production of bitumen with specific characteristics suitable for road construction and other applications.
3. Specifications of Bitumen 100/120
To ensure the quality and consistency of bitumen 100/120, it is essential to adhere to specific specifications. These specifications determine the penetration, softening point, ductility, and other properties of the bitumen. Let’s take a closer look at the key specifications of bitumen 100/120.
Penetration Test and Hardness
The penetration test is a crucial indicator of the hardness of bitumen. It is conducted using a penetrometer, which measures the depth to which a standard needle penetrates the bitumen sample under specific conditions. Bitumen 100/120 has a penetration value between 100 and 120, indicating its semi-hard nature.
Softening Point
The softening point of bitumen 100/120 ranges between 42°C and 49°C. It represents the temperature at which the bitumen softens and loses its original shape under the influence of heat.
Ductility
Ductility refers to the ability of bitumen to stretch without breaking or cracking. Bitumen 100/120 has a minimum ductility of 100 at 25°C, ensuring its suitability for various construction applications.
Other Properties
Bitumen 100/120 also undergoes testing for properties such as loss on heating, flashpoint, solubility in CS2, drop in penetration after heating, and density. These properties determine the performance and stability of the bitumen in different weather conditions.
