Public Works Committee Meeting Date: 04/19/2022 Submitted For: Joe Feriancek, Engineering/Public Works By: Joe Feriancek, Engineering/Public Works Title: Consider Recommending City Council Approval of Plans and Specifications and Award of Contract for Improvement Project #22-09, 2022 Pavement Rejuvenation Improvements Purpose/Background: 5.1. Purpose: The purpose of this case is to consider recommending City Council approval and plans and specifications and award of contract for Improvement Project #22-09, 2022 Pavement Rejuvenation Improvements. 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 striping 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 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 before beginning to use the product in Ramsey. 2021 Rejuvenator Review In 2021, the City treated 2.56 miles of pavement (44,861 square yards) across 6 subdivisions. This spring, Staff visually inspected streets treated during 2021, and found they had held up well. In general Staff observed the treated streets to dry quicker during the spring thaw, as well as noticing less additional cracks in the pavement. When viewed up close, the pavement appears to show less exposed aggregate than non -treated segments. 2022 Proposed Rejuvenator Improvements A map and street segment summary of the proposed 2022 Pavement Rejuvenator Improvements is attached to this case. The project proposes to cover 8.45 miles (151,457 square yards) of bituminous pavement across 21 subdivisions within the City. Staff focused on previous construction pavement age and location when determining the street segments to treat. Priority was given to recent reconstruction projects over recent overlay projects, due to the larger investment by the City on those street segments.
