KEY LARGO, FL – In an effort to preserve county roads and prolong pavement life, Monroe County is continuing the pavement preservation program it initiated last spring. On Dec. 7, Pavement Technology, Inc. will begin treating roads in the Lake Surprise Estates and Sexton Cove subdivisions that were resurfaced in 2016, as well as Grouper Lane, which was recently resurfaced as part of a drainage improvement project. The project should take approximately 3 days to complete. This treatment will extend the life of the pavement up to eight years. The project will not take place on U.S. 1 and will not affect traffic along U.S. 1.

During the treatment period, the road will not be accessible to vehicular traffic for approximately 30 minutes. Access for emergency vehicles will remain available and the contractor will work to minimize inconvenience to residents. The contractor will also place signs the day before in the neighborhoods scheduled to be treated.

The process involves applying a liquid rejuvenator to recently paved roads early in the pavement lifecycle to extend the life and minimize more costly repairs such as milling and resurfacing. The rejuvenator is sprayed on the road and allowed to full penetrate the asphalt before a light coating of manufactured sand is placed over it to provide short term friction and act as a blotting agent. The following day all treated roads are swept with a vacuum sweeper to remove the sand.  The product is environmentally safe and is applied in such a way as to create no runoff into the ocean.

In April, the crew treated 55 miles of county-maintained side and residential roads from Lower Sugarloaf to Little Torch Key that were resurfaced as part of the Cudjoe Regional Wastewater Project. County-maintained residential and side roads in Big Pine Key will be scheduled in early 2021.
