I did at one point hear, but have not seen confirmed, the contractor was being held liable for the error. I assumed this meant they would re-apply it, but I have not seen that happen, maybe they were just refunding us for the work.
Was that the same contractor that applied the crosswalk markings for the LRT? Or is that one a different technology. Those did not last at all, they looked like crap right when they were applied (sloppy application) and then were half worn off after the first winter.
The LRT crossings I believe are a similar product, but a different application, in addition to the surface treatment they also used a hot stencil to emboss a brick pattern into the asphalt surface.
However, some line markings well as our sharrows often use a similar or identical thermoplast product. It does wear well, but it's not invincible, and most of the time it is not in the direct wear tracks from tires, although as others have pointed out it is used for crosswalks and they seem to do okay.
I have no idea if it is the same contractor, but I would expect the contractor who made the error to be able to do it right, I am guessing but all of these road treatments probably depend a lot on conditions, the road must be cleaned, dry, and the right temperature, a contractor pressured for time might try to do it in less optimal conditions just to get it done, and hope for the best.
