5.3. Public Works Committee Meeting Date: 11 / 19/2024 Primary Strategic Plan Initiative: Address infrastructure needs. Title: Consider Recommending City Council Authorization to Prepare Plans and Specifications for 2025 Pavement Maintenance Improvement Projects Purpose/Background: Purpose: The purpose of this case is to consider recommending City Council authorization to prepare plans and specifications for 2025 pavement maintenance improvement projects. Background: The City's current pavement maintenance schedule calls for public streets to receive the following maintenance following construction, overlay, or reconstruction: • Year 2 —Pavement Rejuvenator • Year 3 — Crack Seal • Year 5 —Refresh Pavement Markings (If Applicable) • Year 7 — Crack Seal • Year 10 —Refresh Pavement Markings (If Applicable) • Year 14 — Crack Seal • Year 15 —Refresh Pavement Markings (If Applicable) • Year 20 —Overlay or Reconstruction The above schedule is the typical maintenance schedule based off assumed ideal conditions. Staff reviews the condition of all streets annually and adjusts the schedule of maintenance operations based on actual pavement conditions. IP 25-09 2025 Crack Seal Improvements Crack sealing protects pavement by preventing stormwater runoff from seeping through cracks in the pavement and joints between the pavement and concrete curb and gutter, and utility castings. Reducing future pavement damage due to wet subgrade soils, especially during freeze -thaw cycles. Preliminary review estimates a total of 19.90 miles at an estimated cost of $238,800. IP 25-10 2025 Pavement Rejuvenation Improvements The City uses Reclamite, a pavement rejuvenator, as a front-end treatment to extend the useful life of pavement by 5 — 7 years. Reclamite penetrates, rejuvenates and seals the top 1/2 to 1-inch of the bituminous pavement. The product reduces the surface permeability, which in turn prevents air and moisture intrusion. In essence, this is accomplished by restoring the maltenes lost in the asphalt binder due to natural oxidation. Preliminary review estimates a total of 9.70 miles at an estimated cost of $242,500. IP 25-11 2025 MSA Pavement Marking Improvements Pavement markings are a critical component of driver and pedestrian safety, and are a required maintenance operation per MSA rules and standards.
