If you can see the board impressions in the coax, it's toast.  Replace it.

You didn't say what kind of coax it is, but 9913 is very easily crushed.
According to Mosley, the maker of many military antennas, that's why the
military doesn't use it on the ground or in the ground.  They use RG213, which
will not crush when run over by vehicles with tires.
