Incidental Pavement Repair
C-32 work includes incidental repair — fixing the surface defects that surface treatments alone can’t.
Doing it right
Pothole: square out, clean, fill, compact. Crack: seal promptly to keep water out of the base. Mill and overlay: remove the worn top layer, place a new lift. Recurring pothole = failed base → full-depth repair.
The key judgment is surface vs. base: if only the surface is worn, a patch or overlay works; if the base has failed (a pothole that keeps coming back, or a saturated subgrade), the fix is a full-depth repair, not another thin patch. Sealing cracks early is the cheapest way to keep water from reaching and destroying the base in the first place.
