Highway Overlay
Tandem + pneumatic finish for multi-lane resurfacing density windows.
Highway · municipal · airport · industrial · bridge approach · dam access · port hardstand · quarry haul — each discipline mapped to a Tier 4 Final certified roller class.
Icon-led grid for EOR teams scanning which compaction class belongs on which worksite type. Each card pairs operating weight bands with compaction force and vibration frequency expectations so estimators can shortlist rollers before requesting a full density map package.
Comparison table for project engineers aligning key specs and standards to Dynapac roller classes. Where bridge approaches limit vibration, oscillation modes trade peak compaction force for structure protection — crews should treat that as a constraint, not a universal upgrade over high-amplitude tandem rolling on open highway mats.
| Discipline | Key Spec | Standard | Dynapac Class |
|---|---|---|---|
| Highway Overlay | Compaction force kN + vibration frequency Hz | MoE asphalt density / Superpave | TR-class 10–14 t tandem |
| Municipal Streets | Drum width m + ground pressure kPa | Local agency density band | CT-class 3–7 t + plate |
| Airport Pavements | Tire pressure matrix + kneading passes | Airport authority / FOD rules | PT-class pneumatic |
| Industrial Hardstands | Static line load kg/cm + lift thickness | Geotech embankment spec | SC-class padfoot / soil |
| Bridge Approaches | Oscillation amplitude mm + structure clearance | Structural vibration limits | OS-class oscillation tandem |
| Port Hardstands | Operating weight t + gradeability % | Heavy-duty asphalt rehab | HD-class high line-load |
