To be even more of a pedant, because asphalt is a subset concrete, any comparison between asphalt and concrete is automatically implied as a comparison between asphalt and non-asphalt concrete, and to specify would be redundant.

It's just like when saying "man vs animal", everyone knows that man is a type of animal, but it's implied that it's "man vs non-man animal".

Sounds like the comparison isn't between asphalt and non-asphalt concrete, but between asphalt concrete and cement concrete. Unless the only two possible aggregate binders are asphalt and cement, but that seems unlikely to me.
