Highway overlays, municipal streets, airport edges and industrial hardstands each impose different compaction force, drum diameter and vibration frequency constraints — we map roller classes to those constraints before you bid.
Each scenario lists the density target language paving engineers use, plus the Dynapac machine mix that typically closes the window.
When mat temperature drops fast under wind, tandem rollers with dual amplitude and intelligent pass-count maps keep asphalt density inside MoE bands without adding blind rework passes after midnight.
Narrow lanes and utility cuts need plate compactors and compact tandems that hold edge confinement while crews restore binder and wearing courses beside live traffic.
High-modulus asphalt and FOD discipline demand pneumatic tire rollers with documented tire pressure matrices and clean-water spray systems approved for airside work windows.
Cohesive fills under forklift slabs respond to padfoot compactors with controlled moisture windows so gradeability and ground pressure stay predictable before concrete or asphalt capping.
A short decision path Dynapac application engineers run with estimators before recommending drum diameter and vibration frequency.
Percent of laboratory Marshall / Superpave density, nuclear gauge tolerances and lift thickness from the project specification.
Mat cooling rate, paving width and night-versus-day windows decide whether oscillation, high amplitude or pneumatic finish is required.
Breakdown, intermediate and finish rollers sized so compaction force and vibration frequency cover the tonnage without starving the paver.
