Unique chemistries
to help you build and
maintain better roads.
There’s nothing better
than seeing a newly
paved road stretching for
miles. Smooth blacktop
for as far as the eye
can see. No ruts, no
cracks, no raveling. While
creating that perfect road
is always the goal, mixing
the right combination
of binder, aggregate,
modifiers and polymers
to meet the stringent
specs of the job can
be tricky. And, keeping
it looking great can be
equally challenging.
INTRODUCING
CARGILL’S ANOVA
ASPHALT SOLUTIONS.
™
• Full line of rheology modifiers,
rejuvenators, anti-strip additives
and emulsifiers
• Unique bio-based chemistries
to create new-to-the-world
products.
• Fully functional asphalt binder
analysis and applications lab to
simulate real-life conditions such
as aging and traffic patterns. We
also have the ability to further
characterize asphalt beyond
PG grading, including asphalt
fractionation and molecular size
distribution.
• Cargill can provide consistent
global sourcing and supply of
diverse vegetable oil-based
materials enabling enhanced
price stability and supply
availability.
We take a collaborative approach with
each of our customers to help them meet
their specific needs. No two jobs are
alike – weather, crude type, aggregate and
job specs – all influence product choices.
We understand these varying dynamics
and will work with you to help create the
best solution for your particular situation.
Because we all want to experience driving
on that endlessly smooth blacktop.
Anova Performance Grade
and Rheology Modifiers
™
Anova bitumen additives are viscosity reducers and
rheology modifiers that increase the “useful temperature
interval” (UTI) of bitumen from many different crude
sources through higher softening at lower temperatures
while limiting high temperature grade loss.
A useful tool for asphalt binder producers and contractors, Anova
modifiers can be used to achieve the following:
• Reduce the low temperature grade of the asphalt, to attain -34,
-40 and lower grades.
• Excellent polymer compatiblization and enhancement for polymer
modified bitumen producers.
• Easy grade correction with small dosages (<1%) to counter drifts
during storage and production.
• Paving grade bitumen produced from non-conventional streams.
• Low VOCs which lead to low volatile mass loss (as measured by
the RTFO).
• Access to industry expertise, technical support and formulation
services and our state-of-the-art asphalt application laboratory.

Anova modifiers are significantly more dosage-efficient in
terms of improving the low temperature PG compared to
petroleum-based products (1.9°C grade improvement per
every 1% Anova modifier vs. 0.6°C improvement using 1%
of the commercial aromatic oil). Cargill lab tested using
ASTM D6648.
• Highly compatible with bitumen: Can be easily blended into
bitumen without need of high shear agitation.
• High flash point (in excess of 240°C/460°F) compared to
petroleum-based bitumen modifiers allowing safer handling
without changing current processes.

Anova modifiers have higher flash points than petroleumbased softeners (more than 20°C higher than the high
flash commercial aromatic product). Cargill lab tested
using ASTM D92.

asphalt’s rheological and damage properties.
Anova rejuvenators were developed with the understanding
that “softening” does not equal “rejuvenating.” Anova
rejuvenators rebalance the chemical composition of aged
pavements and bitumen by replenishing high-performing
fractions lost during aging.
These products are excellent tools for a wide range of
pavement types and pavement preservation applications:
• High RAP and RAS mixtures with up to 100% RAP, while
reducing construction temperatures.
• Rejuvenating asphalt emulsions for surface seals and cold
in place recycling.
• Oils and emulsified oils for hot in place recycling and
surface rejuvenating applications.
• Enhances low temperature cracking resistance of asphalt
mixture, even at high RAP content.
• High flash point (in excess of 240°C/460°F) compared to
petroleum-based bitumen rejuvenators, allowing safer
handling without changing current processes.
• Low VOCs which lead to low volatile mass loss (as
measured by the RTFO).
• Has been shown to reduce required compaction
temperature by as much as 20°C in high RAP pavements.
• Access to industry expertise, technical support and
formulation services and our state-of-the-art asphalt
application laboratory.
100% RAP paving using Anova rejuvenators.
Anova Rejuvenator 75%+ RAP project in Netherlands.
The graph to the right shows how aging shifts the master
curve toward lower frequencies (higher stiffness at lower
frequencies/higher temperatures). The Anova rejuvenator
reverses the effect of 20 hours of additional PAV aging by
shifting the curve back toward higher frequencies, while the
commercial aromatic oil recycling agent is less effective.
• A blend of Anova rejuvenator and a Pen 70/100 bitumen
was compared to a similar mixture using a Pen 160/200
bitumen.
• Results show that use of the Anova rejuvenator
significantly improved the compactability of the high RAP
mixture (a 20°C shift in the compaction curve).
• The 4-point bending fatigue test showed that the Anova
rejuvenator significantly improved fatigue resistance and
properties.
• The high-RAP mixture using the Anova rejuvenator passed
the rutting requirement, while the control mixture using soft
bitumen failed the rutting test.

Functional requirement tests were performed on asphalt
mixtures containing approximately 70% RAP (76% RAP
binder replacement ratio). Source of the RAP was open
