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.
