After validation in R&D laboratory, its passive adhesiveness is very good (≥ 75 (2) according to standard NF EN 13614*) on all types of aggregates (Corneal, Quartzite, Diorite, etc.). * Class according to standard NF EN 13808 framework of specifications for bitumen emulsions.

Greener Emulsions

Energy costs have increased significantly, which is why the development of "cold techniques" is being considered in the road industry.

Environmental protection is at the heart of tomorrow's challenges.

EmulGreen™ RB

  • Low CO2 emissions
  • Low ecotoxicity
  • Product made from renewable raw materials
  • Reduced energy costs

Objectives

CO2 Commitment and Net Zero Objectives

Criteria EmulGreen™ RB
