Bitumen 80/100 Description Bitumen 80/100 is a soft paving-grade bitumen that’s used primarily in the production of flexible pavements, especially in mild to cool climates. The “80/100” designation refers to the penetration test result — wherein a standard needle penetrates 8 to 10 mm into the bitumen under standard conditions at 25°C. This grade of […]
What Is Bitumen 60/70? Bitumen 60/70 is a medium-hard penetration-grade bitumen with a needle penetration value between 60 and 70 deci-millimeters (dmm) at 25°C, tested per ASTM D5. It is produced through the vacuum distillation of crude oil residues and is the most widely exported paving-grade bitumen in the world. Its softening point of 49–56°C, […]
Introduction Bitumen Penetration Grade 40/50 is a semi-hard penetration bitumen used extensively in heavy-duty road construction and infrastructural projects. Classified under ASTM D946M specifications, the grade penetrates between 40 to 50 dmm and has improved viscosity and deformation resistance. Because of its thermoplastic nature, Bitumen 40/50 melts at high temperatures and freezes at low temperatures, […]
General Description Bitumen 30/40 Bitumen 30/40 is a semi-hard penetration bitumen of grade bitumen that is derived from vacuum distillation of crude oil. It is viscous and durable and is primarily used in road construction and asphalt pavement manufacturing, especially where there is heavy traffic and high stress. This penetration grade bitumen softens at elevated […]
Description of MC Medium Curing (MC) Medium Curing cutback bitumen is a solvent bitumen blend with a moderately volatile solvent, typically kerosene. It has widespread usage in flexible pavements for surface dressing, prime coating, tack coating, and cold mix asphalt. It possesses a medium evaporation rate with a balance between setting time and workability, which […]
What is Rapid Curing Cutback Bitumen? Rapid curing cutback bitumen is asphalt cement mixed with light, very volatile solvents such as gasoline or naphtha. The solvents reduce the viscosity of the bitumen, making it easier to apply at low temperatures. The most commonly applied grades of rapid curing cutback bitumen are RC-70, RC-250, RC-800, and […]
What is Cationic Bitumen Emulsion? Cationic bitumen emulsion is a stable water dispersion of bitumen droplets with a positive electric charge. The positively charged emulsifying agents (e.g., NH₃⁺ groups) cause them to move towards the cathode when under an electric field, hence the term “cationic.”They repel one another due to the charge and stay suspended […]
Bitumen emulsion is bitumen dispersed in water as droplets half a micron to five microns across, held in suspension by an emulsifier that gives each droplet an electrical charge. That charge is not a technical footnote — it decides whether the binder bonds to your aggregate or strips off it. This guide covers what bitumen […]
Description of Bitumen Number 40 Bitumen Number 40 Bitumen grade 10 is most consumable hard asphalt which is semi solid grade of pure petroleum bitumen categorized in polycyclic aromatic hydrocarbons is normally used for different purposes in the construction business.Bitumen 30 is a type of hard grade building asphalt with penetration starting from No.10 that […]
