What's A Pothole?
Potholes are created when the top layer of pavement and the material beneath – called the base or sub-base – cannot support the weight of the traffic. Two factors are always present in such a failure: TRAFFIC and WATER.
The development of a pothole includes:
- Snow-melt or rain seeps through cracks in the pavement and into the sub-base; if the moisture cannot adequately drain away from the sub-base and soil underneath, it becomes saturated and soft.
- Trapped moisture is subjected to repeated freeze/thaw cycles and with each occurrence, the expanding ice lifts and cracks the pavement more. The passing traffic weakens the pavement, cracking it further.
- As temperatures rise and the ice melts, a void is left under the pavement. This void collects more water, and during the next freeze, the void will enlarge.
- Vehicles driving over the weakened pavement pound it until the surface breaks and collapses into the void below, thus creating a pothole.
If you see a pothole, please contact the Public Works Department at 801-568-2999 or send an email to firstname.lastname@example.org. You can also quickly report it with your Sandy City CityServe app. If you haven’t setup your account, download the app and stay connected to Sandy City.
