Subdivision Earthworks (5–15 acre)
Challenge: Mixed clay and granular lifts, tight lot lines, frequent plate work around utilities.
Package: Mid-class soil compactor + smooth/padfoot drum kit + walk-behind plate compactors for trench backfill.
Five minutes of site questions, three roller recommendations, one service plan. Hamm maps highway, earthwork, quarry and embankment crews to the right drum class.
Each card pairs the pain point on the left with a Hamm machine mix on the right — written for contractors, not brochure committees.
Challenge: Mixed clay and granular lifts, tight lot lines, frequent plate work around utilities.
Package: Mid-class soil compactor + smooth/padfoot drum kit + walk-behind plate compactors for trench backfill.
Challenge: Temperature windows collapse fast; pass overlap errors create density fails.
Package: Two vibratory tandem rollers + pneumatic roller option + intelligent pass mapping for binder and wearing courses.
Challenge: Cohesive fills, dust, and long shifts that punish scrapers and vibration bearings.
Package: Padfoot soil compactors + heavy scraper kits + staged vibration modules at the quarry-belt hub.
Challenge: Vibration risk to decks and adjacent structures on thin asphalt lifts.
Package: Oscillation-capable tandems + amplitude limits coached from the cab + plate compactors for joints.
Challenge: Strict noise and emissions rules inside short overnight closures.
Package: Low-noise tandem class + Tier 4 Final documentation pack + LED lighting service kit.
Challenge: Moisture-sensitive clay lifts where over-compaction wastes hours.
Package: Padfoot soil compactors + lift coaching + nuclear/NDT density coordination checklist.
Paving crews often inherit a “more amplitude is better” habit. On bridge approaches and thin urban overlays, that habit cracks decks and rattles neighbors. Hamm packages call out when oscillation or limited amplitude protects the asset while still hitting density.
Thick binder courses and granular base lifts need vertical energy. Dual amplitude at published vibration frequency lets the superintendent raise compaction force on cool mornings, then drop amplitude as the mat temperature window closes.
Thin wearing courses, bridge decks and work beside occupied buildings favor horizontal shear. Operators keep rolling without transmitting the same vertical impact — a practical answer when the project EOR limits vibration near structures.
Based on your answers, Hamm typically recommends a tandem + soil-compactor mix with intelligent pass mapping. Send the checklist with your inquiry for a packaged quote.
Include site type, daily volume and whether you need oscillation or padfoot drums. We return machine classes, expected compaction force bands and staging options.
