CC Regular Session 5.8. Meeting Date: 03/28/2023 Submitted For: Joe Feriancek, Engineering/Public Works By: Joe Feriancek, Engineering/Public Works Information Title Adopt Resolution #23-063 Approving Plans and Specifications and Award of Contract for 2023 Pavement Rejuvenation Improvements, Improvement Project #23 -09 Purpose/Background: Purpose: The purpose of this case is to adopt Resolution #23-063 approving plans and specifications and award of contract for 2023 Pavement Rejuvenation Improvements, Improvement Project #23-09. Background: Rejuvenator Use History: In 2019, the City Council indefinitely suspended seal coat improvements due to observed issues of pavement stripping under seal coat, which causes approximately the top inch of pavement to strip away from underlying pavement. These areas of stripping originally show as small spots in the surface of the pavement, but quickly migrate across the pavement into large sections. In alignment with many other metro cities confronted with these same pavement issues, Staff feels pavement rejuvenators will provide the greatest overall benefit at the lowest cost. The City is proposing to use Reclamite, a maltene-based petroleum product with the ability to penetrate into asphalt pavement and restore reactive components (maltenes) that have been lost due to the natural process of oxidation. Reclamite has been used nationally for more than 50 years and is proven to add 5 to 7 years of service life to pavements. The application is intended to be performed on pavements 5 years old or less, though several cities are completing pilot project applications on pavement sections older than 5 years. Staff will continue to monitor such applications and adjust future projects within the City of Ramsey based on observed results. Future Considerations: Regional contractors have taken note of metro Cities moving away from seal coating and toward pavement rejuvenators. In 2020 a new product was released by Flint Hills Resources called Replentify. Replentify was tested by other metro cities in 2021 and 2022. Staff is aware comparison testing is being performed by other metro cities which shows promising results that both products improve pavement performance, though more data is needed to confirm the added benefits of Reclamite over Replentify. At this time, Staff recommends continuing to observe how this new product performs in other cities before beginning to use the product in Ramsey. 2021 & 2022 Rejuvenator Review In 2021 and 2022, the City treated 2.56 miles and 9.00 miles of pavement respectively. This spring, Staff visually inspected several of the treated streets and found they had held up well. In general, Staff observed the treated streets to have less additional cracks in the pavement than non -treated pavement. When viewed up close, the pavement appears to show less exposed aggregate than non -treated segments. 2023 Proposed Rejuvenator Improvements A map and street segment summary of the proposed 2023 Pavement Rejuvenator Improvements is attached to this case. The project proposes to treat 4.04 miles (87,850 square yards) of bituminous pavement across 5 MSA street segments within the City. Due to a larger crack seal improvement program in 2023, Staff focused on MSA street
