PORTLAND – A new technique being used to smooth out Portland streets is saving money and keeping work crews on schedule, city officials said.
A “fog seal” is sprayed over the worn pavement and creates a seal that’s expected to last for three to five years. The process costs far less than grinding and repaving the street.
Transportation officials said the city is on track to seal more than 50 miles of roads by the fiscal year next June, and possibly by the end of summer, if the rain holds off.
“Using these new techniques that are more cost-effective, and doing the preventative maintenance, is helping us get on a roll and get ahead,” said Leah Treat, Director of the Portland Bureau of Transportation.
She said the city expects to meet its street maintenance goals this year using a combination of fog seal and grind-and-pave projects.
