Hello,

Nmap traceroute is multi-protocol and will try to select the best
protocol/port combination (ie; one for which he previously got replies
from the target). If the port scanning phase reveals an open 80/tcp
port on the target, then the built-in traceroute can use it.
Nevertheless it doesn't work by injecting the probes into an
established TCP connection.

Hope this answers your question.


Regards.
