Gravel Runway
A lot of the data has to do with CBR (California Bearing Ratio). I believe that the spec contains the details you're after. If memory serves me correctly, you'd be looking for a CBR of around 30 for a gravel runway. Hydro Quebec operates several gravel strips, they should have some details.

Cheers
