Then I guess we have to agree to disagree.
38 yrs of driving on it and also cement trucks, the oil truck twice a year, etc should have it packed. I do not have clay coming up. My gravel was a 3/4 limestone with dust i.e. not washed. When it gets wet it forms "clay looking mud" that is the limestone fines. Being packed really has nothing to do with my drainage issue, In fact, it's so packed the water lays on top and doesn't go anywhere and when it does, it washes out other parts of the drive....which was the point of my post, looking for suggestions of drains, not gravel.
I'll agree to that. Never saw anyone pack a roadbed by driving trucks over it though. What ever you decide to do I hope it works for you. Good luck.
