CC Regular Session Meeting Date: 04/27/2021 Submitted For: Bruce Westby, Engineering/Public Works By: Joe Feriancek, Engineering/Public Works Information 5. 16. Title Adopt Resolution #21-111 Approving Plans and Specifications and Award of Contract for 2021 Pavement Rejuvenation Improvements, Improvement Project #21-11, and Authorizing Purchase Of Pavement Patching Trailer Purpose/Background: Purpose: The purpose of this case is to adopt Resolution #21-111 Approving Plans and Specifications and Award of Contract for 2021 Pavement Rejuvenation Improvements, Improvement Project #21-11, and Authorizing Purchase of Pavement Patching Trailer. Background: Sealcoating Background The intended purpose of sealcoating streets was to prevent existing bituminous pavement from damage due to stormwater runoff, ultraviolet rays from the sun, and petroleum deposits left by vehicles using the streets. In addition, a small amount of oil in the sealcoat emulsion is absorbed by the underlying pavement, helping to rejuvenate up to the top quarter -inch of pavement. In 2019, the City Council indefinitely suspended sealcoat improvements due to observed pavement stripping under sealcoat issues, which causes the top inch or so of pavement to strip away from the underlying pavement in areas that start out small (the size of a quarter), but then grow larger and larger over time until much of the pavement's surface has disintegrated. Since the sealcoat program was suspended, Staff has been exploring alternatives to sealcoat improvements for northern tier states, such as Minnesota. Numerous alternatives have been tried by many cities throughout the metro area. The most common alternatives in use by other cities include fog sealing, micro -thin overlays, and pavement rejuvenators. City Staff have been conferring with Staff from other metro cities including Anoka, Andover, Brooklyn Center, Coon Rapids, Saint Michael and Woodbury to discuss what other sealcoat alternatives are being tried. Based on these discussions, Staff feels pavement rejuvenators will provide the greatest overall benefit at the lowest cost, while minimizing impacts to the traveling public due to the fast cure times. Reclamite Pavement Rejuvenator Background On March 3, 2020, Staff attended a lunch and learn presented by Corrective Asphalt Materials (CAM) and hosted by the City of Coon Rapids. Staff from the following cities were in attendance. • Andover • Brooklyn Center • Circle Pines • Columbia Heights • Coon Rapids • Fridley • Ham Lake • Mahtomedi
