Public Works Committee 6. 1. Meeting Date: 06/16/2020 By: Bruce Westby, Engineering/Public Works Title: Receive Staff Update on 2020 Reclamite Pavement Rejuvenator Pilot Project Purpose/Background: Purpose: The purpose of this case is to receive an update from Staff on a proposed 2020 Reclamite pavement rejuvenator pilot project. Background: The purpose of sealcoating streets is to protect 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. 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. Last fall and winter, City of Ramsey Staff conferred with Staff from other metro cities including Anoka, Andover, Brooklyn Center, Coon Rapids, Saint Michael and Woodbury to discuss some alternatives being tried. Based on those discussions, Staff felt pavement rejuvenators may provide the greatest overall benefit at the lowest cost, while also minimizing impacts to the traveling public due to faster cure times. 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 • Mounds View • New Brighton • Otsego • Ramsey • Saint Francis Corrective Asphalt Materials (CAM) specializes in applying a petroleum maltene-based pavement rejuvenating agent called Reclamite. Maltene-based petroleum products have the ability to absorb or penetrate into asphalt pavement and restore the reactive components (maltenes) that have been lost due to the natural process of oxidation.
