Upper Liard River Bridge Installation

November, 8, 2014 Watson Lake, Yukon, -8 C (18 F).

EZ Street Asphalt was utilized to surface the North and South approaches to the Upper Liard River Bridge for the Yukon Territorial Government (YTG).

Two days prior to installation, EZ Street Asphalt material was produced in Whitehorse, Yukon, with Castle Rock Enterprises, a local asphalt producer. Plant location temperatures ranged from -4 C (25 F) to -10 C (14 F) with light snow throughout. The material was trucked 438 km (272 miles) from Whitehorse to the Watson Lake bridge installation site at ambient temperatures.

Asphalt produced from used vegetable oil

A high-quality B100 biodiesel was provided by EZ Street Canada’s biodiesel supplier in Delta, British Columbia and made up 30% of the EZ Street blend used for this high-performance surfacing material. There is extensive data indicating a significant installed performance benefit for this type of asphalt material using biodiesel vs fossil fuel diesel. Biodiesel based asphalt also has production safety and environmental benefits - a 170 C or higher flash point and no detrimental environmental risk factors. The use of biodiesel also means significant greenhouse gas mitigation for the Yukon Territorial Government.

Installation

EZ Street Asphalt was installed by Castle Rock Enterprises using some of the same crew used for production. A traditional asphalt surfacing paver and rolling equipment (steel wheel and rubber tire rollers) were utilized resulting in no seams or joints. Minimal hand work or raking was required and the crew were not exposed to harmful fumes.

Post Installation Results

The Yukon Territorial Government (YTG) was very pleased with the results of their first use of EZ Street Asphalt technology. Regardless of the extreme climactic conditions, the project installed easily and quickly. EZ Street Asphalt will provide a high-stability load bearing surface for any location no matter how remote and at practically any time of the year which will greatly extending YTG’s road maintenance and construction season. This will mean an increase in their capacity to provide high performance highways and roads to the people of the Yukon.
