2. INTRODUCTION 2.1 Authorization The preparation of this report was authorized by the Ramsey City Council on August 28, 2018. This project has been designated as City Improvement Project No. 19-03. 2.2 Program Overview In support of the City's long-term Street Maintenance Program, the existing bituminous pavement section will be reconstructed. Damaged concrete curb and gutter will be replaced and minor storm sewer repairs will be made. Other appurtenant work will be completed as outlined in this report. The City' s pavement evaluation process involves a visual evaluation of each street's pavement surface based on the type, extent and severity of each pavement distress observed. Numerous types of pavement distresses may exist within a pavement section including, but not limited to, alligator cracking, block cracking, longitudinal cracking, transverse cracking, rutting, raveling, shoving, potholes and patches. This field data is then used to rate the pavement condition. The City uses the Pavement Surface Evaluation and Rating (PASER) system to rate pavement condition. A PASER rating is a numerical index between 1 and 10 indicating the condition of a pavement based on the various pavement distresses recorded during visual observations. A PASER rating of 10 represents brand new pavement, while a PASER rating of 1 represents a pavement section that has fallen into complete disrepair requiring full reconstruction. In the summer of 2018, City Staff evaluated and rated the condition of the pavement along the Wood Pond Hills and Chestnut Ridge street segments. A PASER rating of 2 was assigned to 146th Avenue, Helium Street, and the northern half of Krypton Street. A PASER rating of 4 was assigned to the southern half of Krypton Street, including its termini cul-de-sac. 2.3 Scope City of Ramsey Improvement project 19-03 proposes to reconstruct the existing bituminous pavement, to remove and replace damaged concrete curb and gutter sections, and to complete other appurtenant work on three street segments within the Wood Pond Hills and Chestnut Ridge residential neighborhood including; 146th Avenue between Nowthen Boulevard and Junkite Street, Helium Street between Sunwood Drive and 146th Avenue, and Krypton Street from Sunwood Drive to its termini cul-de-sc. These street segments total approximately 3,310 lineal feet (0.63 miles) in length. The existing bituminous pavement is proposed to be reconstructed using the Full Depth Reclamation (FDR) process. This involves reclaiming the bituminous pavement section between the existing concrete curb and gutter sections, along with the existing aggregate base, then hauling and disposing of any excess reclaim material off site, spreading and compacting the remaining reclaim material on top of the reshaped and compacted subgrade, then placing 3 Y/z -inches of new Feasibility Report Wood Pond Kills & Chestnut Ridge Street Reconstructions City of Ramsey Project No. 19-03 6
