AkzoNobel mimics nature to develop additive which makes roads safer
(Thomson Reuters ONE) -
October 29, 2014
AkzoNobel has launched an additive for road salt which helps to protect against
frost damage and makes driving safer.
Inspired by the ability of certain animals to withstand cold and prevent ice
forming in their bodies, Ecosel®AsphaltProtection is a fully biodegradable
additive for de-icing brine. It works by slowing the freezing process, resulting
in soft, slushy ice, rather than hard, abrasive ice. After in-depth research and
development, the product is available to customers in Italy and the Netherlands.
"Adding Ecosel®AsphaltProtection to normal winter road salt can reduce frost
damage by around 50 percent," explained Werner Fuhrmann, member of the AkzoNobel
Executive Committee responsible for Specialty Chemicals. "Municipalities and
governments will substantially benefit from the results - less need for road
repairs, fewer traffic jams, lower maintenance costs and greater road safety."
He added that by extending the service life of roads, CO(2) emissions will also
fall, not only because of fewer traffic tailbacks, but also because there will
be a reduced need for materials and energy for maintenance.
"The additive not only protects people and the planet, it also makes economic
sense as it brings down the total cost of ownership," continued Fuhrmann. "In
addition, launching this product further highlights our strategy of sustainable
innovation and represents the latest addition to our growing portfolio of eco-
premium products."
By mimicking nature, AkzoNobel researchers were able to tackle the repeated
freeze-thaw cycles that affect asphalt mixtures. Water trapped inside asphalt
expands by about 9 percent when it freezes, breaking up the road itself. Passing
traffic then further accelerates the damage.
Ecosel AsphaltProtection works by preventing the water trapped inside the
asphalt pores from turning into hard ice. It encourages the formation of slushy
ice, which is mechanically weaker than the asphalt and therefore substantially
reduces the risk of damage.
Destined to be a key contributor to the Sustainability and Transportation
pillars of the company's Human Cities initiative, the new product was
successfully tested in cooperation with the Dutch, Danish, Swedish and Austrian
road authorities.
