Hydraulic vibration recalibration · drum amplitude verification · Tier 4 Final emissions sampling on Dynapac roller fleets.
Structured inclusions for highway overlays, soil embankments, airport pavements and municipal patch programs — each tier lists audit scope and documentation.
| Tier | Inclusion | Drum / Hydraulic Audit | Documentation |
|---|---|---|---|
| T1 — Highway Overlay | 24/7 paving dispatch + vibration module warranty window | Quarterly eccentric-shaft bearing & amplitude check | ISO 9001 audit pack + Tier 4 NOx log |
| T2 — Soil Embankment | Scheduled padfoot tip rotation & scrapers | Monthly ground-pressure & moisture-window review | Lift density trend chart for EOR review |
| T3 — Airport Pavement | Annual pneumatic tire roller re-certification | Tire pressure matrix + kneading pattern verify | Airport authority density & FOD checklist |
| T4 — Municipal Patch | Pre-season plate & small tandem calibration | Water-spray flow, edge-guard & vibration interlock | MoE asphalt mat density report package |
How Dynapac field engineers convert hour meters and density complaints into a documented reliability program for paving fleets.
Define paving kilometers, soil lift counts and asphalt tonnage inside the service contract so spare kits and FSE hours match the real duty cycle.
Sample DPF/SCR under load using ISO 8178 C1 cycle references when municipal or airport authorities require emissions evidence with the roller fleet.
Verify amplitude, frequency and hydraulic pilot pressure against factory maps; replace eccentric bearings before compaction force drifts off specification.
Submit MTBF / MTTR and ISO 4406 cleanliness trends to the paving engineer of record after each contracted service window.
