I would say as Rome relied on its military might their top technologies would be in connection with the army so!.!.

Roads and surveying technology: ie the groma because good roads led to fast movement of the army and supplies and eventually led to better trade!.

Concrete: which led to sturdy long lasting buildings such as aquaducts and bridge building!.!.!.better access and clean plentiful water supplies sometimes in very arid conditions!.

Ballistic weapons: Such as the onager or ballister which helped in siege warfare giving the Romans a massive advantage in attacking fortified towns and settlements!.

Prepacked forts: Premade forts which could be assembled very quickly on campaign making it very easy for the Romans to gain a solid base in hostile territory!.

Good heavy armour!. From chainmail to the legionary overlapping armour it was solid and heavier than many of their enemies!.

Sorry thats all I can think of at the mo!.!.
