2. INTRODUCTION 2.1 Authorization The preparation of this report was authorized by the Ramsey City Council on July 11, 2017. This project has been designated as City Improvement Project No. 18-02 2.2 Program Overview In support of the City's long-term Street Maintenance Program, the entire existing bituminous pavement section will be reconstructed using a full -depth reclamation (FDR) process. The existing bituminous curb is proposed to be replaced by this project. 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 2017, City staff evaluated and rated the condition of the pavement along the HY-10 Ramsey street segments. A PASER rating of 2 was determined for 147th Avenue and Ferret Street. A PASER rating of 7 was determined for 146th Avenue, however, as previously noted a portion of this street segment was reconstructed with a temporary bituminous pavement section as part of the Armstrong Interchange project. 2.3 Scope City of Ramsey Improvement Project 18-02 piupuses to reconstruct the existing bituminous pavement using the FDR process, and to complete other appurtenant work on 146th Avenue from Ferret Street to its termini cul-de-sac, 147th Avenue from 380 feet west of Armstrong Boulevard to Ferret Street, and Ferret Street from 146th Avenue to its termini cul-de-sac which totals approximately 1,400 feet (0.27 miles) in length. A map showing the location and scope of the proposed improvements is included as Figure 1 in Appendix A. Feasibility Report HY-10 Ramsey Street Reconstructions City of Ramsey Project No. 18-02 Page 5
