Greetings,

My house contains an addition which is a slab poured over asphalt. The
asphalt eventually "biodegraded" and another slab had to be poured over the
fist slab.

Hope this helps,
William

can concrete be poured over existing asphalt and result be used as slab
for
house/living area?

any outgassing problems from the asphalt into the living area?
