It’s in its infancy, but a new innovation could save the city thousands of dollars.
Brittany Kustra, a communication advisor for the City of Calgary, said during the summer crews typically fill over 5,000 potholes.
However, “when they’re not using that equipment to fill the potholes there’s nothing else that equipment can do,” said Kustra.
Roads maintenance crew members thought there had to be another way to use the machines. That’s when they developed the slip-in asphalt carrier.
“Crews can take asphalt from other construction sites, so lets say they rip up a manhole and they’re doing some work there, they can reuse that asphalt,” she said.
To recycle the asphalt, Kustra said you apply an emulsion, a liquid solution, to the asphalt carrier and to the asphalt. You then load the material into the carrier and bake it at 350 degrees Fahrenheit for eight to 12 hours.
Kustra said the prototype performed well during the first trial. Now, the roads department is planning to add this equipment to six more units in 2017.
“How much money are we talking about saving, is it vast amounts of dollars?” Bruce asked.
According to Kustra, every time they run the trial they can do up to about four tonnes of asphalt.
“For every tonne that we recycle we’re saving $141 dollars,” she said.
