Bitumen Penetration Grade – EU Standard – Bitumen 30/45

PENETRATION GRADE BITUMEN

EN Standard – Bitumen 30/45 

Penetration grade bitumen 30/45 is a semi-hard grade bitumen mostly used in hot mix asphalt, road construction and asphalt pavements. The penetration range of bitumen 30/45 is between 30 to 45 tenths of a millimetre. Penetration grade bitumen 30/45 is suitable for various regions due to its thermoelastic property that makes bitumen soften in high temperatures and harder in low temperatures. Bitumen 30/45 is ideally used in warmer climates as it has a lower penetration value that works against high temperatures and protects from deformation and cracking.

USES:

 

Penetration Grade Bitumen 30/45 is ultimately used in asphalt pavements and road construction.

  • Bitumen grade 30/45 generally finds its usage in making asphalt pavements and structures in warmer regions and heavy traffic areas.
  • Highly used in the hot mix asphalt for creating wearing courses and bases for paving surfaces.
  • As bitumen 30/45 has a high softening point and viscosity it works against adverse weather conditions and ensures structure integrity.

QUALITY STANDARD:

 

Penetration Grade Bitumen 30/45 conforms to the European Standard EN 12591, which sets stringent requirements to ensure quality and performance.
