The email states that this new road coat is not supposed to leach
contaminants into the nearby environs. Does anyone know aught about this?
I had the thought that since birds often take 'dirt baths' in the road, what
effect will this have on their feathers? Also, since birds eat dirt, gravel,
clay, etc. for a variety of reasons, how safe will this be for them? I am
both curious and concerned regards how much testing has been conducted.
