Green Street, Saskatoon
Paving crews working with Duraclime asphalt in Saskatoon, SK

In October 2008, Lafarge's Central Asphalt division proposed an innovative, environmentally friendly road construction project called "Green Street" to the City of Saskatoon, the largest city in the Canadian province of Saskatchewan.

 

A few months later, the city authority awarded Lafarge a contract to construct two streets under the Green Street program. The order involved roughly 1,800 metric tons of recycled concrete and asphalt and 540 metric tons of Lafarge's Duraclime™ asphalt.

 

Duraclime reduces both the energy costs and fumes associated with traditional asphalt. The secret lies in the temperatures needed to heat the product-a maximum of 130 degrees C, or 266 degrees F, compared with more than 150 degrees C, or 302 degrees F, for conventional asphalt concrete mixes.

 

"The Green Street project is based on a global environmentally friendly approach," explains Wayne Heaslip, operations manager at Lafarge Central Asphalt. "Duraclime is manufactured using recycled asphalt (RAP) ... [and] the concrete used in [Green Street's] curb and sidewalk construction was designed to meet LEED [Leadership in Energy and Environmental Design] specifications, the American standard for green buildings. [In addition,] the aggregates used for the [project's] base materials are 100 percent recycled concrete for the sub-base and 100 percent recycled asphalt for the base."
