WarmGrip D-450

Next-Generation Bitumen Mix Performance-Improving Additive

Worker-friendly warm mix chemistry for all bitumens

WarmGrip D-450 EU is a next-generation, worker-friendly warm mix additive that enables easier compaction at reduced paving temperatures and extends pavement life by creating powerful chemical adhesion of bitumen to aggregate, protecting from moisture damage and resultant pavement distresses such as raveling, pothole development and rutting. It is engineered to deliver reliably strong performance with a wide variety of bitumen and aggregate combinations.

WarmGrip D-450 EU is added directly to bitumen and is compatible with all bitumen types and modifiers. WarmGrip D-450 EU is used to design mixes that conform to typical specifications, including:

  • AASHTO T283: Method of Test for Resistance of Compacted Bituminous Mixture to Moisture Induced Damage,
  • AASHTO T324: Method of Test for Hamburg Wheel-Track Testing of Compacted Hot Mix Asphalt (HMA),
  • AASHTO R35: Standard Practice for Superpave Volumetric Design, and equivalent BS EN test standards, including EN 12697-11: Determination of the affinity between aggregate and bitumen
