Help identifying floor and how to lay LVT

[Tuharax]

I have taken up tiles in the kitchen and some lino. Half the floor was tiles half was lino. Under is what appears to look like black tiles. However they are not tiles. I have read this could be asphalt, bitumen paint or bitumen for sticking down old marley tiles. I am leaning toward it was used to stick down old marley tiles. I have attached some photos. The riles that were down had a blue underlay underneath this was rock solid and brittle ie is chipped and smashed when I got the floor up. Can anyone help me work out what floor I have? What do I need to do with it to screed for LVTs?

The old craftlon tiles. Used to fit loads of them the late 80s. The sub floor could be asphalt. If so that’s a Dpm so remove tiles safety , advice on the government website. Could have small traces of asbestos in them but you can still remove them.
Then a 3mm coat of ardex NA

Thanks. Tiles are all up I am guessing it’s ashhalt for the sub some of it chipped away looks black all the way through so it wouldn’t be concrete with painted bitumen. What’s odd is the blue material under the tiles. The floor ship said this might have been a DPM but not sure why it’s there as the asphalt woukd have been the DPM. Also not sure why the other half of the floor which had different tiles they were adhesived straight onto the asphalt

The blue in the pics is vinyl tiles or vinyl sheet.

Is that used as a DPM then it was on top of the asphalt and then glued to the top tile

No. Vinyl tiles were stuck to direct to asphalt years ago
