CC Regular Session 7. 6. Meeting Date: 05/10/2022 Submitted For: Bruce Westby,Engineering/Public Works By: Joe Feriancek, Engineering/Public Works Information Title: Adopt Resolution#22-106 Approving Plans and Specifications and Award of Contract for 2022 Pavement Rejuvenation Improvements, Improvement Project#22-09 Purpose/Background: Purpose: The purpose of this case is to adopt Resolution#22-106 Approving Plans and Specifications and Award of Contract for 2022 Pavement Rejuvenation Improvements, Improvement Project#22-09. Background: Rejuvenator Use History: In 2019, the City Council indefinitely suspended sealcoat improvements due to observed pavement stripping under sealcoat issues,which causes approximately the top inch of pavement to strip away from the underlying pavement. These areas of pavement stripping originally appear as small dark areas and depressions in the surface of the pavement,but rather quickly expand into larger and larger depressions roughly one-inch deep within the pavement surface. In alignment with many other metro cities confronted with these same pavement stripping issues, Staff researched alternatives to sealcoating and determined that of the alternatives available at the time,pavement rejuvenators likely provided the greatest overall benefit at the lowest cost. Therefore, in 2020 the City completed a pilot demonstration project following approvals from the Public Works Committee and the City Council,by applying Reclamite, a maltene-based petroleum product with the ability to penetrate into asphalt pavement and restore reactive components (maltenes)that have been lost over time due to the natural process of oxidation and help bituminous pavement retain its flexibility to reduce cracking, to the south end of Ute Street in the Stanhope Terrace development,which was reconstructed in 2018. Since this pilot project was completed, the pavement treated with Reclamite appears to be less porous and drain better than the pavement segment to the north that was reconstructed at the same time but was not treated with Reclamite. Staff will continue to monitor the two sections to evaluate the ongoing benefits of Reclamite. Reclamite has been used nationally for more than 50 years and is appears to add 5 to 7 years of service life to pavements. The application is generally intended to be performed on pavements 5 years old or less, although some cities, including Woodbury, are trying pilot projects on older pavement sections to see if older pavements would benefit from the application of pavement rejuvenators. Future Considerations: Regional contractors have taken note of metro Cities moving away from sealcoating and toward pavement rejuvenators. In 2020 a new product was released by Flint Hills Resources called Replentify. Replentify was tested by other metro city in 2021, and Staff has knowledge of it's larger scale use in 2022. At this time, Staff recommends observing how this new product performs in the field in other cities before trying this product in Ramsey. Staff would prefer to have more time to observe how Reclamite is working before adding another tool to our pavement maintenance toolbox. 2021 Rejuvenator Review In 2021, the City treated 2.56 miles of pavement(44,861 square yards) across 6 subdivisions. This spring, Staff
