Public Works Committee Meeting Date: 06/21/2022 By: Bruce Westby, Engineering/Public Works 5.4. Title: Consider Recommendation to City Council to Temporarily Increase Funding for Pavement Management Program Purpose/Background: Purpose: The purpose of this case is to consider making a recommendation to City Council to temporarily increase Pavement Management Program funding to address the immediate street reconstruction bubble needs. Background: Pavement Management Program Background The City maintains over 186 miles of bituminous paved City streets and is in the seventh year of its current Pavement Management Program (PMP). The primary goal of the PMP is to perform the proper pavement management (maintenance/rehabilitation) operation at the proper time to maximize the life of the pavement as cost-effectively as possible. When streets are constructed or reconstructed using today's design standards, and when pavement management operations are proactively performed on those streets on a regular basis afterwards, at least 60-years of useful life is anticipated from new and reconstructed bituminous pavement sections. Current bituminous pavement management operations include; • Cracksealing — Protects existing pavement by preventing stormwater runoff from seeping through cracks in the pavement and joints between the pavement and concrete curb and gutter and utility castings, minimizing future damage due to wet subgrade soils, especially during freeze -thaw cycles. The City annually crackseals about 25 miles of bituminous pavement on its public street system. • Overlays — Protects existing pavement similar to cracksealing, while also increasing the structural or load carrying capacity of the pavement. The City typically overlays up to 4 miles of pavement on its public street system annually. • Reconstructs — Pavement reconstruction projects remove and replace severely damaged pavement with new pavement sections. Reconstruction projects may also include removal and replacement of damaged concrete curb and gutter on urban sections, or re -grading ditches and re -shouldering on rural sections. The City annually reclaims/reconstructs up to 2 miles of pavement on its public street system. The City of Ramsey's current proactive pavement management schedule for improved public streets is generally as follows; • Cracksealing - 3 years following construction, overlays or reconstruction, then every 7 years after. • Overlays - 20 years after construction, overlays or reconstruction. • Reconstructs - 60 years after construction or reconstruction. The pavement management schedule for each street segment is adjusted based on actual pavement conditions. City staff annually reviews and rates the pavement condition of all public streets using the Pavement and Surface Evaluation Rating (PASER) system. PASER ratings range from 1 to 10, with 1 being a failed pavement section in total disrepair, and 10 being a new pavement section.
