Method for Producing Bitumen 60/70

Introduction

Bitumen 60/70 is a widely used penetration-grade bitumen in road construction and industrial applications. Notably, this type of bitumen features a penetration range of 60 to 70 dmm at 25°C, ensuring excellent performance in various climatic conditions. To emphasize, the production of Bitumen 60/70 follows specific processes to guarantee optimal quality, durability, and stability. Furthermore, our competitive pricing and exceptional product quality make us a trusted supplier worldwide.

Field of Invention

The method for producing Bitumen 60/70 relates to bituminous compositions, their production techniques, and their application in pavement construction. More importantly, the focus is on developing bituminous compositions with solvent-free bitumen emulsions that offer controllable, temperature-dependent interfacial rheology, significantly enhancing performance and efficiency.

Production Process

1. Primary Distillation

Initially, Bitumen 60/70 originates from crude oil through a controlled distillation process in petroleum refineries. That is to say, this step separates lighter fractions such as gasoline, kerosene, and diesel, leaving behind heavier bituminous residue.

2. Vacuum Distillation

Subsequently, in vacuum distillation, the remaining heavy residue undergoes further refining under reduced pressure. This method effectively allows bitumen separation without decomposition. In addition, the process conditions are carefully controlled to achieve the desired penetration grade.

3. Blending & Modification

To obtain the precise penetration and viscosity characteristics of Bitumen 60/70, blending of different vacuum residues may be necessary. Moreover, modifications using polymers or additives further enhance properties such as resistance to deformation and aging, thereby improving durability and quality.
