Pavement Construction for GA Aircraft
Where would I find information on pavement construction. A local farmer I know, uses a C182 off his own property, his makeshift runway is a graded dirt road down one side. Problem is it becomes very muddy after rain and unuseable. So he wants to seal it with a cape seal. A cape seal is a version of chipseal, where a layer of bitumen is spread on the dirt then a truck lays small gravel in the bitumen which is pressed into the bitumen then allowed to set. The cape seal is a slurry that's laid over the chip seal and provides a smooth surface very much like hotmix asphalt but at 1/4 of the cost.
Question is, for a runway that will only be used maybe 5 times per week, what sort of subgrade and preparation would be required for aircraft up to 3000 kg. the underlaying ground is thick clay type soil that's hard as a rock in summer.
Are light GA aircraft harder on pavements that trucks.
