<br /> . As work on Dunlap Street was not programmed into the 1992 budget, funds may not be available <br /> for the City to fund its portion of reconstruction costs as outlined by the Assessment Manual. <br /> The second option for improving the roadway would be a maintenance type project to remove and <br /> patch the worst areas of the pavement section, provide a bituminous leveling course to re-establish <br /> drainage patterns and then overlay the entire roadway with two to four inches of bituminous wear <br /> course. The thickness of the overlay would be greater than the one and one-half inch overlay <br /> projects constructed on residential streets due to the heavy truek and commercial traffic using <br /> Dunlap Street. This option would require that some areas of the existing roadway be chosen for <br /> removal while other areas would be merely overlaid. <br /> Unfortunately, the existing pavement is distressed to the extent that the vast majority of the surface <br /> . would need to be cut and patched. It would not be cost effective to attempt to patch only localized <br /> areas. In addition, the estimated "life" of a roadway with this type of overlay project is <br /> significantly less than the "life" of a roadway rehabilitated with a cold in-place recycling project as <br /> described by the third option. It is therefore concluded that the option of cutting and patching <br /> areas of the existing pavement followed by a bituminous overlay is not a viable option. <br /> The third option is to perform a cold in-place recycling project. This type of maintenance project <br /> - <br /> was similarly discussed in October 1991 for Stowe Avenue between Cleveland Avenue and Lake <br /> Johanna Boulevard and in April 1992 for Round Lake Road West, south of Trunk Highway 96. <br /> This option would address the entire existing pavement, rather than only selected areas as <br /> described in the second option. We have discussed this type of project with Mr. Dan Schacht, <br /> Ramsey County Maintenance Engineer, who directs the County's Cold In-Place Recycling (CIR) <br /> Program, The County's goal in starting this CIR program was to find a method to improve a <br /> . <br /> 5 <br />
