Would you eat the asphalt?


I wouldn't eat most stuff that goes into the garden soil (compost, manure,
loam, perlite, worms). The small amount of asphalt shouldn't be
harmful/toxic to your plants. Just add something to the soil so that it
doesn't become compacted.

What is the asphalt made of? I have no idea, but I wonder if
(e.g.) used motor oil is a constituent, or anything else rich
in metallic compounds? That could be an issue if the plan is
to grow vegetables above.
