Once something is contaminated with bitumen,
especially something old, like your parquet flooring,
that was probably fixed with a hot-poured bitumen 'glue',
there isn't much choice.
However if the bitminous layer is brittle it may splinter/fall off when hit edge on with a bolster,
leaving the underside relatively clean,
with the remainder removed by not (too) much sanding.
Try a couple, and you may be lucky as presumably the actual wood is a dense hardwood
which has not 'sucked up' any of the bituminous goo.
If you can get the bituminous layer off,
you are probably good to go with a modern material, probably acrylic based.
