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. 18-00. 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 will be replaced with B618 concrete curb and gutter, plus 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 2017, City staff evaluated and rated the condition of the pavement along the Stanhope Terrace street segments. A PASER rating of 3 was determined for Lite Street, 154th Lane and 153rd Court. 2.3 Scope City of Ramsey Improvement Project 18-00 proposes to reconstruct the existing bituminous pavement, remove existing bituminous curb and replace with B618 concrete curb and gutter, and to complete other appurtenant work on Ute Street from Alpine Drive to its termini cul-de-sac, 154th Lane between Ute Street and Roanoke Street, and 153rd Court from Roanoke Street to its termini cul-de-sac which totals approximately 2,800 linear feet (0.52 miles) in length. The existing bituminous pavement section is proposed to be reconstructed using the FDR process. This involves reclaiming the entire bituminous pavement section from back of curb to back of curb, along with a portion of the existing aggregate base, hauling and disposing of excess reclaim material off site, spreading and compacting the reclaimed material on top of the reshaped and compacted subgrade, then placing 3.5 inches of new bituminous pavement on top. The resulting pavement design will generally meet current City design standards. A map showing the location and scope of the proposed improvements is included as Figure 1 in Appendix A.
