PAQUETVILLE (CNB) - A new, environmentally friendly asphalt technology is being used on five paving projects across New Brunswick, Transportation Minister Denis Landry announced today. He released details of the department's use of warm-mix asphalt while visiting one of the project sites.


Landry also announced that his department has awarded a contract to St. Isidore Asphalt Ltd.,

valued at $1.28 million for a total of 8.2 km along Route 340 in three areas: Route 11 toward H. Sealey Road; Caraquet River to Notre-Dames-des-Érables and the Portage Road area to the Paquetville village limit.

"Our government is encouraging changes across departments that reduce our carbon footprint, and we are acting together on our climate change action plan," said Landry.

"The Department of Transportation has taken a leadership role in this by implementing a more environmentally responsible way to improve our roads."

Warm-mix asphalt has special additives that reduce the temperature required in production and paving. Unlike traditional hot-mix asphalt, which requires temperatures of up to 150 degrees Celsius, warm-mix asphalt is produced at 100 degrees

Celsius, according to Landry. This reduced temperature means less energy is needed to produce the mix, resulting in a substantial decrease in fuel consumption, green house gas emissions and fumes.

The Department of Transportation tested the technology in St. Martins, Moncton and on the Acadian Peninsula over the past two years. It has been closely monitored for quality and durability, with results showing the technology to be at least as durable as traditional mixes.

Landry announced the department has awarded other paving contracts that will feature warm-mix asphalt:

Landry added that the Transportation Department will make a presentation about its use of warm-mix asphalt during the annual conference of the Canadian Technical Asphalt Association. About 300 people are expected to attend. This will be the first time that the department will be featured in the association's journal.
