UNITED STATES<br />
In the State of Missouri,<br />
200 kilometers south of<br />
Saint Louis, a 108-kilometer<br />
section of Interstate 55<br />
is being resurfaced.<br />
The project – one of the first<br />
to be launched as part of the<br />
USA’s economic stimulus plan –<br />
is being managed by teams<br />
from Delta. Launched in<br />
July 2009 and broken down<br />
into two phases, it should be<br />
completed by the end of 2010<br />
Interstate 55: Delta puts on a show!<br />
and will involve a total of<br />
245,000 tons of asphalt mix.<br />
One of the specific features<br />
of this project is the use<br />
of warm mix, a first in the State<br />
of Missouri! More than<br />
70,000 tons of Ecomat ®<br />
(out of a scheduled total<br />
of 140,000 tons) have already<br />
been applied, making this<br />
the biggest warm mix project<br />
ever undertaken by the Group<br />
in North America. Manufactured<br />
site-seeing 09<br />
and applied at lower temperatures<br />
than conventional hot mix,<br />
warm mix technology generates<br />
energy savings and reduces<br />
greenhouse gas emissions.<br />
In 2009, the use of warm mix<br />
increased significantly<br />
throughout <strong>Colas</strong> companies<br />
in the USA and Canada. <br />
