General Description of Bitumen 20/30 Penetration Grade Bitumens 20/30 are specified by the penetration and softening point test. The designation is by penetration range only. The penetration grade bitumens have a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. The Bitumen mode is dependent on temperature. […]
Definition of Bitumen 200/300 This Penetration grade of Bitumen 200/300 is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. Penetration Grade Bitumen is a standard bitumen usually used as a Paving Grade Bitumen essential for road construction and for the production of asphalt pavements with superior properties, and it’s […]
General Description of Bitumen 120/150 Bitumen 120/150 is semi-hard penetration grade bitumen used as a paving grade bitumen which is suitable for road construction and repair. This unique temperature-viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability, and application temperatures of bitumen. bitumen is a standard Penetration Grade of […]
Definition of bitumen 85/100 Bitumen Grade 85/100 is a type of penetration grade bitumen that is produced by the non-destructive refining of crude oil during petroleum refining. exporting bitumen is penetration hard grade and softening between 85 to 100. bitumen is hard penetration grade bitumen used as paving grade bitumen suitable for road construction […]
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 Slow Curing (SC) Cutback Bitumen is also referred to as a blend of asphalt cement and low-volatility petroleum solvents such as fuel oil or diesel. The blend reduces the viscosity of the bitumen, which is easier to use in cold weather or cold mix operations. “Slow curing” refers to the slow evaporation of the […]
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 […]
