Grade selection by road class
Local roads and residential streets — 7 Gauge Mix. Arterial roads and main routes — 10 Gauge Mix. Highways, freight corridors and bus routes — 10 Gauge as the baseline, 14 Gauge for deep failures. Rural unsealed crossover patches and rough sealed surfaces also take 10 or 14 Gauge for structural durability.
Carry both 7 and 10 Gauge on the truck and you cover almost every road-class callout from one vehicle.
