Repair bitumen/asphalt type flooring

[Adam78]

I have a concrete floor which has some bitumen or asphalt type flooring. It has cracked in some corners - see pic.

How do I repair this?

Hi,

I'm only a DIY'er and maybe completely wrong!

But, I wonder if something as simple as a pothole repair kit might work:
