Bitumen 50/70

Introduction of Bitumen 50/70

Bitumen 50/70 is a thick, black substance used in making roads and other construction projects. The “50/70” tells us two things: how hard it is and how easily it can move.

The “50” means it’s medium-hard. Imagine it like a piece of rubber that’s not too soft or too hard.

The “70” means it can move a bit more easily. Think of it like honey – not too runny, but not too thick either.

This combination of being medium-hard and a bit flowy makes it perfect for roads. It stays strong even with lots of cars driving on it. It also stops water from getting in, so it’s good for roofs and other places where we need to keep things dry. Basically, it’s like a super-strong glue that holds everything together!

 

 Exploring Bitumen 50/70 Technical Specifications

It quality is defined by its specific properties and characteristics, evaluated through various tests including penetration, viscosity, softening point, shape, heat loss, and flash point.

Key Tests for Bitumen 50/70

The critical tests for suppliers and customers revolve around the softening point and flash point, pivotal in assessing the Asphalt usability and performance. According to ASTM D36 standards, Asphalt 50/70 exhibits a softening point range of 49 to 56°C and a flash point of 250°C, aligning with similar grades like 60/70 Asphalt

Applications of Asphalt 5070

It finds extensive use in road construction projects within temperate regions, serving as a fundamental component for producing essential asphalt mixes and insulation layers.

Formulation and Composition

The formulation of the Asphlat is characterized by its elemental composition, comprising approximately 87% carbon and 8% hydrogen, alongside trace amounts of sulfur (up to 5%), nitrogen (1%), oxygen (1%), and metallic components at 2000 ppm. Notably, it primarily consists of highly concentrated polycyclic aromatic hydrocarbons, defining its chemical composition and properties.

Quality and Safety Assurance

We guarantee quality and safety, undergoing rigorous testing to meet industry standards. Its reliable composition and secure packaging ensure confidence and peace of mind for suppliers and customers alike.

Packaging Specifications

Typically packaged in new 180 kg steel drums and 1000 kg Jumbo sacks, ensuring convenient handling and storage for various industrial applications
