Potholes are back across the island of Montreal. Here’s information on why they are formed, the procedure of the City of Côte Saint-Luc in filling them, and how much it costs.

 

Territory

Côte Saint-Luc is responsible for all roads on our territory. However, the City of Montreal is responsible for the south side of Côte Saint-Luc Rd. from Décarie Blvd. to a few blocks east of Westminster Rd. Motorists who spot potholes on that side can call 3-1-1 to speak to a Montreal information agent.

 

How potholes are formed

Potholes are a result of the freeze/thaw cycle, which deteriorate road surfaces. If water seeps into crevices of the road and then freezes, sections of the pavement are forced up. Then the weight of vehicles travelling over the section of road breaks the pavement and the asphalt is forced out. That’s why potholes are more frequent in the spring or even during the winter right after a period with a sudden rise and decrease in temperature.

 

How we identify potholes

City employees who are frequently on the road from Public Works, Public Security, and volunteers from vCOP and EMS are on the lookout for potholes and report them to the Public Works office. Residents can help by calling the Public Works office at 514-485-6868 or using the SeeClickFix app on a smartphone to notify the city of a pothole.

 

How we fill potholes

There are two types of asphalt used to fill potholes, cold mix and hot mix. They are used at different times of the year. Cold mix asphalt contains an additive that prevents it from hardening and makes it more granular. Hot mix asphalt doesn’t bind to frozen surfaces, which is why it shouldn’t be used in winter.  Cold mix asphalt, however, is a temporary solution.  Once the weather gets warmer,  we have to re-fill the potholes, but this time with hot mix asphalt, which is a more permanent solution.

 

Our procedure

From May to November, we have a crew that is dedicated to minor asphalt repair and potholes. During the rest of the year, we have crews to fill potholes as needed.

 

When we receive a call from a resident or employee about a pothole, a crew is sent out to fill it. Most potholes take just a few minutes to fill.

 

Pothole costs

It costs about $2.60 of hot-mix or cold-mix to fill the average pothole. Of course, this doesn’t include the labour cost or cost to operate and maintain the equipment used. One team of two employees and equipment will cost about $800 each day to fill 15 potholes. Therefore, an average pothole costs Côte Saint-Luc about $50.
