Bitumen on concrete and ufh

[vik2001]

I removed parquet flooring in a bungalow and the concrete is covered in bitumen. A little thick in some places.
I want to lay ufh matts and install ufh. How do I tackle the bitumen. Is it acting as a dpc?

I don't want the place smelling with the ufh

Try bitumen remover.
Not something I've used so I don't know how good it is.
