Accessible SurfacesStandard
Firm and stable surfaces require max ½ in aggregate with minimal voids for wheelchairs.
VolumeFormula
Volume (yd³) = (length × width × depth in ft) ÷ 27.
Material ComparisonTable
Common trail surfacing options.
| Material | Cost | Durability |
|---|---|---|
| Crusher fines | Medium | High |
| Wood chips | Low | Low |
| Boardwalk | High | Very high |
Compaction Lifts
Spread surfacing in 3–4 in lifts and compact each before adding the next.
Source Locally
Match aggregate color and geology to reduce visual impact.
Dust Control
Wet material before spreading in dry conditions to protect crew lungs.
Safety Notes
- Wear dust mask when spreading dry crushed stone.
- Plate compactors are loud — use hearing protection.
