Pavement Management Report P a g e | 4 More extreme rehabilitation projects are needed to restore projects in the Marginal category. For pavements in the upper range of the category, mill and overlays are recommended. Roadways that fall into the lower range of the Marginal category usually require a more thorough rehabilitation. Pavement reclamation or full depth mill/overlay is usually needed to adequately repair road at this point. Prior to any mill and overlay or bituminous removal and replacement, pavement coring is strongly recommended to determine if the pavement base structure is in good enough condition to support the intended project. If there are issues in the base and subgrade layers, many pavement preservation methods are not feasible. Reconstruction is recommended to be performed on streets that fall into the Problem category. Usually, roads in this condition have deteriorated beyond the point where any other maintenance activity is cost effective. Again, pavement coring is recommended prior to any design work to determine the appropriate maintenance project. Reconstruction can also help to address subsurface issues such as drainage or increase in traffic capacity. As pavement deteriorates, certain maintenance strategies are no longer feasible. It is important to address minor distresses before they become worse. Pavement maintenance solutions get exponentially more expensive as the roadways degrade so performing routine maintenance is crucial. Preventative maintenance is the most cost-effective solution for cities looking to maximize their budget and keep their roads in good condition. Appendix A features a PCI map and Appendix B lists the PCI of each surveyed segment. WSB can provide additional analysis, recommendations, or maintenance planning if requested.
