Paving Problems - May 29, 2008

The Department of Transportation and Works says it's not seeing the types of problems with asphalt on provincial roads like what some municipalities are experiencing. The Town of Grand Falls - Windsor is considering deferring paving this year because of premature pavement failure. The Department of Transportation and Works says a review of its asphalt pavement specifications was done two years ago and recommendations were made to produce more durable pavement. One of the changes implemented was limiting the amount of natural sand within the pavement mixture to a maximum of 15 per cent.

Two years ago?

That would be around the time of the still-sooper-sekrit Trans-Labrador Highway chipseal study, innit?
