Bitumen 50/70: Enhanced Road Performance

Bitumen 50/70

Exploring Bitumen 50/70 Technical Specifications

Bitumen 50/70  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 bitumen.

Applications of Asphalt 50/70

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.
