the steeper the pitch the faster gravel will migrate to the shoulders...
The ideal grade is just enough pitch to keep the water running off the road (into the ditches) fast enough to prevent it from running down the road...
in hilly or mountainous country...by pitching the road into the hill (against nature) it makes recovering displaced gravel possible...granted it is harder cutting ditches and requires more culverts but there is usually much less seasonal maintenance needed...
