“We all know that freezing and thawing causes damage to our asphalt
mixes,” said Soliman. “The main idea of this research is to understand the
mechanism of the freeze-thaw damage. We need to know which components
of the mix contribute more to the freeze-thaw damage to be able to
modify our mixes to have better performance in those conditions.”
Common asphalt mixes are comprised of aggregate of various sizes
(coarse particulate material like stones and gravel) and an asphalt binder
that acts as a glue to hold the mix in place.
“Pavement projects
are large investments
– multimillion-dollar
projects – so you don’t
want to take a risk and
do something new
without understanding
or without having
good information on
what could happen
to it in the future.”
– Haithem Soliman, University of
Saskatchewan Engineering
