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.

4. Applications of Bitumen 100/120

Bitumen 100/120 finds extensive use in various applications within the construction industry. Its versatility and performance make it the preferred choice for the following applications:

Road Construction and Repair

Bitumen 100/-120 is widely used in road construction and repair projects. It serves as a binder for asphalt mixtures, providing strength and durability to the pavement. The excellent adhesion properties of bitumen 100-120 help in creating a stable and long-lasting road surface.

Asphalt Pavement Production

Asphalt pavements, commonly known as blacktops, consist of a mixture of bitumen and aggregates. Bitumen 100/120 acts as a crucial binding agent in the production of asphalt pavements. The specific penetration grade of bitumen ensures the desired performance and longevity of the pavement.

Roof Insulation

Bitumen 100/120 is also utilized in the production of roof insulation materials. Its waterproofing properties and resistance to extreme weather conditions make it an ideal choice for roofs in residential and commercial buildings.

Membrane Sheet Manufacturing

In the construction industry, bitumen 100/120 is used in the manufacturing of membrane sheets. These sheets are widely used for waterproofing applications in basements, tunnels, and other structures.

5. Advantages of Bitumen 100-120

Bitumen 100/120 offers several advantages, making it a preferred choice in the construction industry. Let’s explore some of these advantages:
