Ecofriendly pavement repair

Nordmann is proud to partner with Kao Chemicals to support customers looking for bitumen emulsifiers, anti-stripping agents and special additives for road construction.

bitumen emulsifiers, anti-stripping agents and special additives

The company is now supplying DANOX® PATCH, a new and unique additive that reduces the viscosity of bitumen and achieves good mixing strength.

DANOX® PATCH has minimal impact on the environment, making it a superior choice for cold asphalt mixtures – particularly when compared to conventional petroleum-based products.

Everyone knows them: potholes. Many roads are pocked and pitted by this type of damage, and holes should be repaired quickly to avoid further deterioration of the pavement. Only later, with a certain amount of lead time and in-depth planning, can road surfaces be properly and thoroughly repaired “from the ground up”. Ensuring initial, near-immediate repairs are not only key for the safety and comfort of drivers, but also for the preservation of a road’s service life and the prevention of more severe and extensive damage to its surface.

To repair potholes, the asphalt industry typically uses cold mix asphalt (CMA). The main advantages of this are:

  • Environmentally friendly
  • Low energy costs
  • Immediately ready for use
  • Easy to apply
  • No heavy compacting
  • No additional equipment required
  • Long-term workability
  • All-weather solution
  • No prior surface treatment necessary
  • Roads can be immediately re-opened for traffic

To achieve good workability of CMA at low temperatures without compromising asphalt stiffness at operating temperatures, the viscosity of the bitumen must be reduced.

KAO’s launch of DANOX® PATCH has introduced a unique additive onto the market that reduces bitumen viscosity and provides cold asphalt mixes with superior strength.

DANOX® PATCH is a solution that offers great versatility and is easily added to hot bitumen or emulsions during the mixing process.

DANOX® PATCH’s main advantages include:

  • Clear and transparent liquid
  • Environmentally friendly, low environmental impact
  • Non-flammable, non-volatile
  • 100% active
  • RAP-compatible
  • Compatible with all types of aggregates
  • Compatible with PMB


Distributed in Austria, Bosnia, Bulgaria, Croatia, the Czech Republic, Germany, Hungary, Romania, Serbia, Slovakia, Slovenia and Switzerland.
