LOCAL NEWS-
You have probably noticed Crookston City workers busy seal coating various streets throughout Crookston this week. KROX was wondering what is seal coating and what does it do for the streets so we talked to Crookston Public Works Director Pat Kelly who said the type of coating they are using is called chip sealing. “We sweep the street off clean, then put down an oil called an MC-800.  We get the oil from Calumet right here in town, so it works out pretty good.  After a layer of that, we come in with our chip spreader and spread the rock on it and roll it and let it sit about a week before we sweep up the excess rock,” said Kelly.
Seal coating is a surface treatment and keeps the road from oxidizing. “The effects from the sun can become apparent over time with visible rocks and an older look,” said Kelly.  “Seal coating will extend the life of the pavement.”
Kelly told us that they have been seal coating the streets every summer from before he was here.  He told us that they usually coat about a mile and a quarter of city street a year.
