Key Technical Properties of Bitumen 80/100
Penetration Bitumen 80/100 exhibits consistent behavior during asphalt production and in service. Its physical properties support strong adhesion, smooth compaction, and long pavement life.
Typical Technical Characteristics:
Penetration (25 °C): 80–100 dmm
Softening Point (Ring & Ball): ~46–54 °C
Ductility @ 25 °C: ≥ 75 cm
Flash Point: ≥ 230 °C
Solubility in Trichloroethylene: ≥ 99%
Specific Gravity: 1.02–1.06 (approx.)
These parameters ensure adequate binder performance in various asphalt mixes and climates.
