Every two years, the City of Edmonton evaluates our city roads for surface distress. And every five years, they measure the structural integrity. All roads evaluated are rated on a scale 0-10 (with 10 being mint condition) and then all the individual scores are combined to create an overall score called the Pavement Quality Index. This process is just the initial step the city uses to determine which roads are going to get fixed each year. There are many other aspects such as budgets and remaining service road life that get factored into what gets repaired.
