BITUMEN STANDARDS GRADE

  • ASTM D 946 and AASHTO M 20 (Penetration @ 25°C)
  • ASTM D 3381 and AASHTO M 226 (Viscosity @ 60°C)
  • ASTM D 6373 and AASHTO M 320 (PG-Graded Binder)
  • EN 12591 (Penetration @ 25°C) → NF EN; BS EN; DIN EN; etc.
  • AS 2008 (Viscosity @ 60°C)
  • SABS 307 (Penetration @ 25°C; Viscosity @ 60°C after RTFOT)
  • IS 73 (India) changed in 2006 from PEN grades to VG Grades (based on Viscosity @ 60°C); however, CRMB modified bitumen is still graded based on penetration.

POLYMER MODIFIED BITUMEN

  • ASTM D 5976; ASTM D 5840; ASTM D 5841 (based on polymer type; now outdated and not used in the USA, but still used in some developing countries)
  • ASTM 6373 and AASHTO M 320 (PG-Graded Binder; applicable to Unmodified and Polymer Modified Bitumen)
  • EN 14023 (Framework Standard for Polymer Modified Binder)
  • AUSTROADS Framework Specifications (Australia)

BITUMEN EMULSIONS (ANIONIC; CATIONIC; UNMODIFIED; POLYMER MODIFIED)

  • USA Anionic Emulsions: ASTM D 977 and AASHTO M 140
  • USA Cationic Emulsions: ASTM D 2397 and AASHTO M 208; Polymer Modified Cationic Emulsion: AASHTO M 316
  • Europe: Harmonized Framework Standard EN 13808 for Cationic Unmodified and Polymer Modified Emulsions; many different national

(Note: Internationally there exist a very broad range of emulsion specifications; many of them are technically inaccurate and confusing.)

CUTBACK BITUMEN

  • ASTM D 2026, D 2027 and D 2028 for Slow, Medium and Rapid Curing Cutback
  • AASHTO M 81, M 82 for Rapid and Medium Curing Cutback
  • EN 15522 Cutback and Fluxed Bituminous Binder
