Proposed Resurfacing and Road Maintenance Plan

Proposed Resurfacing Projects Map

The default map view is for 2020. To view the other proposed paving plan, click the arrow next to "Pavement Management Plan" in the "Layers" box in the upper right portion of the screen and select the year.

Simply click on the “legend” tab in the upper right corner to view pavement project plans along with other data, and the highlighted road to view the location and method for that specific project.

The four maintenance methods used on the map are:

  • Cold In Place Recycle – This repair method will be used on select roadways where the base has failed over the general length and must be structurally strengthened. This method pulverizes the existing base and adds additional materials such as Portland cement or liquid asphalt cement. The enhanced base is compacted and allowed to cure. Following the cure time, it will be topped with a new hot mix asphalt wearing surface.
  • Micro – This repair method is formally known as micro-surfacing. This is for roads that are structurally sound but the age of the asphalt is showing heavy surface wear. This thin (> ½” ) material is applied to the old roadway providing a new wearing surface that gives a new smooth driving surface and slows the reflection and growth of the pavement cracks. While it does provide a newer look to a road, it does not look exactly like a traditional resurfaced roadway. This technique is generally 50-60% less expensive than the traditional mill and overlay.
  • Mill and Overlay – This method is what you are most familiar with. The roads first have the existing asphalt top layer removed by a milling machine and then followed by the application of new asphalt. This is done in areas where the asphalt deterioration is such that it cannot be preserved or the crack widths are too large for the application of micro-surfacing.
  • Rebase and Overlay - This repair method is what we use to address localized areas of roadways in need of base repair. When the base failure of a roadway is not continuous over long distances, this repair method is the most efficient and cost effective. This is a version of mill and over lay in that where base work is needed, the milling machine removes additional material to a depth of 4-6”. Then hot mix asphalt is placed as the new base material. When using this method no lane closures are required overnight. Once all the base repairs are complete, the final surface layer can be applied.
