RheoFalt HP-AM

The advantages

Organic Rejuvenator

100% natural resin based

  • RheoFalt HP-AM is based on the CNSL technology, these bio-resins are not in conflict with agricultural areas or with natural/rain forests.
  • The production of the RheoFalt HP-AM is based on CO2 natural energy sources.
  • Because of the Bio-Based nature, RheoFalt is binding CO2 emissions in Asphalt which is on its term a long storage of greenhouse gasses in a road application.

100% renewable

  • Because the raw materials which are used to produce RheoFalt are based on a by- product of food products (cashew nuts) the RheoFalt is fully comprised of durable renewable raw materials.

Directly Polymerized (patented)

  • Ventraco Innovation Centre BV developed a patent method to directly polymerize the raw CNSL into an “Asphalt Maltene” like resin, with a minimum of green energy. The polymers behave similar to the maltene fraction in the bitumen.

Solvent free

  • RheoFalt HP-AM is a brown viscous liquid resin at ambient temperatures, the resin is solvent free and a 100% resin polymer.
  • During production / polymerization no solvents of environmental chemicals are used, only pure natural raw materials.
  • All energy needed for the production of RheoFalt HP-AM is green renewable energy.

Flux-oil free

  • RheoFalt HP-AM is flux-oil free, it will not evaporate in time.
  • Flux-oils will have a temporary softening effect.
  • Flux-oils do not change/rejuvenate the aged bitumen
  • The nature of a flux-oil is to evaporate (flux) out of the bitumen
  • Heavy aromatic solvents are often used to flux bitumen

Vegetable oil free (plasticizer free)

  • While the HP-AM is a liquid at normal working temperature it is not an oil (even though is looks like an oil)
  • Oil in general is considered to work as a plasticizer in bitumen (already mentioned in the early fifties)
  • The viscous properties of bitumen will dominate the behavior of penetration bitumen when oils are used to modify or rejuvenate bitumen
  • Oil can be used in bitumen but only in very small addition rates, overdosing is always a risk. When oil is overdosed, the bitumen will show a sharp change in penetration and softening. Asphalt produced with elevated oil levels will show a greater vulnerability to rutting in comparison to normal bitumen.
