Transcript of PROJECT SPOTLIGHT HERB GRAY PARKWAY - lafarge.ca · Lafarge Eastern Canada CORPORATE OFFICE 6509...
HIGHLIGHTS:
LOCATION:Rt. Hon Herb Gray Parkway,(formerly Windsor-Essex Parkway), Windsor, Ontario near Detroit Border
Project Type: Open Graded Drainage Layer (OGLD)
Authorized Contractor: The Windsor Essex Mobility Group (WEMG)
Subcontractor: Amico Infrastructures, Canada
Developer/Owner: Ministry of Transportation Ontario, Infrastructure Ontario
Engineer/Consultant:Golder Associates
Project Timeline: 2013-2014
Materials Supplied: 606,000 T Hydromedia®
Lafarge’s Hydromedia® Ensures a Rut-free Open Grade Drianage Layer for Concrete HighwayThe Rt. Hon. Herb Gray Parkway is an 11km stretch of Highway 401 designed to link Canada’s
busiest land border crossing at Windsor/Detroit, and the existing Highway 401. It was needed
to alleviate traffic congestion on local roads, which would allow the easy movement of goods
and people. The Ministry of Transport of Ontario and Infrastructure Ontario commissioned the
parkway that was constructed between 2011 and 2015.
Materials for Rut-Resistance Open Graded Drainage Layer Needed When Amico Infrastructures of Cambridge, Ontario won the open graded drainage layer (OGDL)
contract for the 3-lane wide 11km concrete-paved stretch of the Rt. Hon Herb Gray Parkway,
general manager Dwayne Dawson was excited and concerned. This was a huge job, spanning
13 months, but it also carried some risks. It would be important to adhere to the project
schedule to avoid overage penalties and provide a rut-free surface for another contractor to lay
the concrete pavement on top of.

Consultation with Lafarge on aggregates leads to cement-based Hydromedia®
Dawson reached out to the Lafarge local market area manager, as they were planning
a porous asphalt OGDL and needed aggregates and advice on mitigating rutting. The
manager convinced Dawson to use Hydromedia as it offers better control and is easier to
place than other options. Unilke an asphalt-based OGDL, Hydromedia remains stable when
a concrete pavement is being placed on top of it during hot summer days. That would
mean there would be no rutting caused by heavy equipment going over the OGDL. There
was some concern as most drainage layer projects in Canada have been asphalt based.
Hydromedia® Placed with Great ResultsIn August 2013, Amico began the OGDL construction. Hydromedia was placed to a 10mm
tolerance with a Vogele Super 2100 paver. Dawson noticed the results immediately, as the
material was easy to place. During the thirteen month long construction period, they kept
to their construction schedule, because of the ease of placement, so did not incur any
penalties. Amico was able to hand over a flat level surface for the next contractor to lay the
concrete pavement surface.
Dawson was pleased with the results as using Hydromedia kept costs down, improved
productivity and produced a high quality rut-free OGDL.
“Amico was able to incorporate Hydromedia for the drainage layer under the 401 pavement structure, Amico was able to reduce overall costs, increase production, improve the project schedule and maintain quality. Amico will look to implement this product on other projects moving forward.”
