Pavement Management Program
The Pavement Management Program is focused on using preventative treatments to extend the lifespan of pavements, thus minimizing the need for and expense of complete road reconstruction. Over time, roads deteriorate due to weather, traffic and other factors. The City uses strategies such as crack sealing, curb replacement, surface sealing and overlay to keep roads in good condition. Streets are assessed to determine the best approach and treatments are applied based on the assessment. This work is funded by the half-cent transportation sales tax, which helps us keep our streets safe and well-maintained.
Crack sealing prevents water damage by filling gaps with rubberized sealant and is often placed in advance of overlays and surface treatments to improve performance. The best time to seal cracks is October through March when cracks are the widest.
Surface seal uses a pre-mixed slurry of rock, polymer asphalt binders, cement and filler materials to seal the entire roadway at a depth of approximately 1/4 inch.
Curb repair is done annually to replace deteriorated curbs, and typically precedes the mill and overlay program. Replacing curbs in advance of resurfacing helps avoid damaging new pavement.
Overlay replaces the street with a thick asphalt layer after milling 1.5 – 2 inches of the old pavement and spraying it with a tack coat layer.
Residents may notice differences in which streets are treated and when because prioritization is based on the condition of the pavement and available resources. Construction can be inconvenient but these updates are crucial for maintaining road quality and safety.
