A temporary road for heavy trucks uses composite or thick HDPE mats (18–20 mm HDPE for mid trucks; solid composite 38–47 mm for dump trucks, semis, and 150 t+ haul) laid as a continuous, pinned roadway so axle loads do not rut soft ground. The governing calc is axle load ÷ contact area; a fully loaded dump truck exerts far more per axle than a car. On weak subgrade, pair mats with geogrid/geotextile underlayment to raise effective CBR. Composite haul roads replace aggregate import and are reusable for 10–20+ years — beating both steel plates and stone.
A car can cross grass; a loaded dump truck destroys it. Heavy-truck temporary roads live or die by axle math and subgrade prep. This guide covers the calculation and the build.
Axle-Load Reality
| Vehicle | Typical axle load | Mat response |
|---|---|---|
| Delivery van | ~2–5 t/axle | 12.7–15 mm HDPE |
| Loaded dump truck | ~10–12 t/axle | 20 mm HDPE / composite |
| Semi / heavy haul | ~10–20 t/axle (legal) | Solid composite + grid |
| Overweight / crane | Much higher | Solid composite 150 t+ |
Build Steps for Truck Haul
- Calculate worst axle from the heaviest truck's spec.
- Survey subgrade CBR — dictates grid + thickness.
- Lay geotextile separator over fluid fines.
- Place geogrid + angular infill if CBR is low.
- Lay composite mats (pinned, staggered) on top.
- Monitor settlement; top up infill if needed.
Truck Road vs Alternatives
| Factor | Composite road | Aggregate | Steel plates |
|---|---|---|---|
| Reuse | 10–20+ yr | No (consumed) | Decades |
| Aggregate haul | Minimal (grid) | Massive | None |
| Install speed | Days | Days | Slow (crane) |
| TCO | Low over reuse | High/project | High upfront |
When Composite, When Grid+Mat
- Firm subgrade → composite mats alone (38 mm).
- Soft but bridgable → 20 mm HDPE + geotextile.
- Weak/no firm layer → geogrid + infill + composite.
- Repeated heavy axle → always grid+composite.
Procurement Note
Own the haul-road mats (factory-direct composite at 30–50% below branded) and reuse across projects — the TCO beats aggregate and rental. Verify third-party axle-load tests and shear-rated connections.
Frequently Asked Questions
What mat for a loaded dump truck?
20 mm HDPE or composite on firm ground; solid composite (38–47 mm) plus geogrid on soft subgrade. The limiting factor is axle load, not total truck weight.
Do I need geogrid under a truck road?
On weak subgrade with no firm layer, yes — grid confines soil and raises effective CBR so the mat does not deflect into mud. On firm ground, composite alone suffices.
Is a mat road better than aggregate?
For temporary/repeat haul, yes — reusable 10–20+ years, minimal aggregate haul, lower TCO and carbon versus a stone road.
