Dealing with Asbestos Floor Tiling
I asked a related question here some time ago. I was told that (a) the safest way to take these up was to heat them and the adhesive so they could be lifted without breaking, and that (b) encapsulating them under another floor was an entirely reasonable approach. Asbestos is not automatically a hazard if it isnt experiencing wear and shedding fibers, just as lead paint that isn't peeling or being sanded isn't necessatily a hazard.
