The province is testing a new maintenance machine that could prove recycling is just as effective for roads and bridges as it is for cans and bottles.
This Saskatchewan-made product uses "hot in place" technology to recycle asphalt material on the spot for repairs of potholes and other road surface failures.
Highways and Infrastructure Minister Wayne Elhard was out on the Arcola Avenue exit ramp to Highway 1 to get a first-hand look at the pilot project in action today.
"What's so exciting about this new machine is it heats up the asphalt concrete material around the failure, softens it, re-mixes it and relays it all in one process," Elhard said. "You don't have the expense and environmental impact of producing new asphalt concrete and hauling it to the repair site. It's exactly the kind of innovative and practical technology that I want to see tested and applied in the rejuvenation of our highway system."
The "hot in place" maintenance vehicle uses a square box with heaters which is lowered onto the failed area to heat up the asphalt concrete material, softening and melting it. This same box contains metal teeth that are lowered into the asphalt, dragging it forward and loosening the material. A rejuvenating agent is added along with a small amount of new material. To improve the environmental benefits even further, reclaimed asphalt from other projects will be tested as the "new" added material. The remixed asphalt concrete is then raked over and rollers are used to compact it back down.
Battle River Asphalt Equipment Ltd. based out of Cut Knife is the manufacturer of the asphalt recycling equipment. The company, founded by Tom Wiley, holds several U.S. patents on "hot in place" technology in use across North America and Asia.
The City of Regina and Communities of Tomorrow research group are also partners in the pilot project, testing and evaluating the equipment and assessing performance along with the Ministry of Highways and Infrastructure. The combined research and analysis will be shared among the partners.
"This equipment has the potential to be an important tool in the future of road maintenance, not just here in Saskatchewan but other jurisdictions as well," Elhard said. "We are excited to be involved in assisting a Saskatchewan manufacturer test and develop their product."
