How to Ship a Paving Machine or Asphalt Finisher: Trailer Types and Permit Requirements
Asphalt paving machines — also called asphalt finishers or pavers — are among the more challenging pieces of construction equipment to transport due to their low ground clearance, wide screed extensions, and heavy operating weights. Compact pavers start around 12,700 lbs, while large industrial pavers can exceed 56,000 lbs and require oversize permits in most states. This guide covers trailer selection, loading technique, and permit requirements for the full range of paving equipment.
Asphalt Paver Weight and Dimension Ranges
Paving machines vary significantly by class. Here are typical transport specifications:
| Class | Operating Weight | Transport Width | Transport Length | Transport Height |
|---|---|---|---|---|
| Compact Paver | 12,000–16,000 lbs | 4–6 ft | 14–17 ft | 7–9 ft |
| Mid-Size Wheeled Paver | 28,000–34,000 lbs | 8–9 ft | 18–20 ft | 9–10 ft |
| Large Tracked Paver | 40,000–56,000 lbs | 9–11 ft | 20–24 ft | 10–12 ft |
Note: Screed extensions dramatically increase transport width. Most pavers are shipped with the screed retracted to its minimum transport width. Verify the retracted transport width before booking — some large pavers with full-width screeds exceed 8.5 ft even when retracted.
Trailer Selection for Paving Machines
Paving machines have unique loading requirements due to their low ground clearance and front-mounted hoppers. Trailer selection must account for load angle as well as weight and dimensions:
- Tagalong / Tilt-Bed Trailer: Suitable for compact pavers under 16,000 lbs. The tilting bed provides a low load angle that accommodates the paver's low clearance. Deck length of 18–20 ft is recommended.
- Lowboy Trailer: The preferred choice for mid-size and large pavers. The low deck height (17–24 inches) provides the shallow load angle (under 12 degrees) that paving equipment requires. Also keeps tall machines under height limits.
- RGN (Removable Gooseneck): Required for the largest pavers (over 40,000 lbs) or when the machine must be driven onto the trailer from the front. RGN trailers can handle up to 150,000+ lbs and provide maximum deck flexibility.
Permit Requirements by Paver Class
Permit requirements depend on the paver's transport dimensions and the states being crossed:
- Compact pavers (under 8.5 ft wide, under 80,000 lbs GVW): Typically no oversize permit required. Standard flatbed or tilt-bed transport.
- Mid-size pavers (8–9 ft wide): Width permit required in most states. Some states allow up to 8.5 ft without a permit; others require permits for anything over 8 ft.
- Large pavers (9–11 ft wide, 40,000–56,000 lbs): Oversize width permit required in all states. Some large pavers also require overweight permits if the combined GVW exceeds 80,000 lbs. Escort vehicles may be required for loads over 12 ft wide.
Loading Considerations for Paving Machines
Loading a paving machine requires attention to several factors that don't apply to most other equipment:
- Load angle: Paving machines have very low front clearance due to the hopper and conveyor system. The trailer's load angle must be under 12 degrees to avoid dragging the front of the machine. Lowboy trailers are specifically designed for this requirement.
- Screed position: The screed must be fully retracted and locked in transport position before loading. Some screeds have hydraulic locks; others require mechanical pins.
- Conveyor system: The conveyor and auger system should be secured in transport position. Loose components can shift during transit and cause damage.
- Fuel and material: The hopper should be empty and clean before transport. Residual asphalt in the hopper adds weight and can harden during transit, making cleanup difficult.
Tie-Down and Securement
Paving machines are secured using chains through the machine's designated tie-down points. Key requirements:
- Minimum 4 chain tie-downs for machines over 10,000 lbs, with combined WLL equal to at least 50% of machine weight
- Chains should be attached to the machine's frame tie-down points — not to the screed, conveyor, or other components
- The machine should be in neutral with the parking brake set before securing
- Rubber-coated chains or edge protectors should be used where chains contact painted or finished surfaces

Common questions
What trailer is best for shipping an asphalt paving machine?
For compact pavers under 16,000 lbs, a tilt-bed tagalong trailer works well. For mid-size and large pavers, a lowboy is the preferred choice because it provides the low load angle (under 12 degrees) that paving machines require due to their low front clearance. Large pavers over 40,000 lbs may require an RGN trailer.
Do I need a permit to ship a paving machine?
It depends on the paver's transport width. Compact pavers under 8.5 ft wide typically don't require oversize permits. Mid-size and large pavers (8–11 ft wide) require width permits in most states. IronHaul will confirm permit requirements based on your machine's specific transport dimensions.
Should the screed be retracted before shipping?
Yes. The screed must be fully retracted to its minimum transport width and locked in position before loading. This is critical both for legal width compliance and for safe transport. IronHaul drivers will verify screed position before securing the machine.
Does the hopper need to be empty before transport?
Yes. The hopper should be empty and clean before transport. Residual asphalt adds weight and can harden during transit, making cleanup difficult and potentially affecting weight compliance.
