I doubt it'll be used on any high volume roadways though.
According to this page, a 2023 review showed some significant collision reductions so it would make sense to do at intersection approaches, though I can't find the the 2023 review to see how durable and cost effective it is. If it's like chip sealing it'll get around 5 years on high volume roads. |
I recall them using chip sealing on a section of deerfoot years back and several people at my workplace came to work the same day with their windshields totally destroyed. That stuff should never be used on city roads.
