What these hazards do
Heaves and potholes change the geometry under the edge without warning.
- Frost heaves raise a section of road, so an edge set to the normal surface meets a ramp or a step.
- Potholes drop the edge or the shoe suddenly, then the far side acts as a step up.
- Combined with snow cover, they are invisible, so the driver cannot see them.
Crew adaptations
| Action | How |
|---|---|
| Map | Keep a route sheet with hazard locations from driver reports and daylight patrols |
| Mark | Use stakes or markers where permitted; note landmarks for each spot |
| Brief | Tell new and relief drivers about every marked hazard before they go out |
| Slow | Reduce speed on known stretches |
| Lift or float | Raise the plow or use float where the surface is uneven, if your equipment supports it |
| Review | Match each damaged edge to the location where it happened |
Working with the road owner
A dated list with photographs is what gets a repair scheduled.
- Send a dated list with photographs and locations.
- Add the cost of damage to equipment if you can.
- Ask for temporary repairs or warning signs.
Edge choices
On routes full of heaves, some crews try flexible or segmented edges that can absorb shocks. Treat that as a trial, not a promise, and log wear and damage for a season before changing more trucks.
After a strike
- Use the five-minute triage checklist.
- Record the place and add it to the sheet.
Early-winter patrol
Drive the worst routes in daylight before the first big storm, with a second person noting locations, ideally at low speed with a camera. Ten minutes per route often finds the biggest spots, and a printed map of the results can go into each truck. Repeat after a thaw-and-freeze cycle, since new heaves can appear quickly and the earlier map may be out of date.
Boundary: practical advice only; no statistics. Follow your agency’s marking and safety rules.
