Project Details

For over 15 years, the City of Barrie has employed Denso® Reinstatement Tape when completing utility cuts. Concerned with disbondment of asphalt cold joints, the road supervisors started having workers install Denso Reinstatement Tape on the internal perimeter of utility cuts after base asphalt and prior to top lift installation. Over a decade of freeze and thaw cycles, the joints pictured here have stayed intact. Dunlop Street, a very busy street that runs the length of downtown Barrie, has seen it’s share of traffic, construction and infrastructure repair and still, the joints protected with Denso Reinstatement Tape remain closed, water tight and without cracks. By utilizing this proactive approach, municipalities like Barrie enjoy the immediate benefi t of sealed joints without returning to router and seal and also considerable savings over the years from the lack of need for crack sealing. Denso Re-instatement Tape is a modifi ed polymer bitumen strip which will compress and rebound keeping water out of joints where asphalt meets asphalt, steel and concrete.
