What we called pop corn paving material was tried in South Carolina to help the water to run thru. But it would not hold up and came up in sheets. A lot of money was thrown away on that idea.
I'd think that paving material might be OK for a PARKING LOT, but here's NO WAY I'd expect it to hold up when used as a road surface, especially with heavy traffic. I assume its "sheet" failure was related to subsurface water freezing and disrupting the paving.
That and the water pressure under it when you run across with a car or a big truck. Here in Georgetown they paved a parking lot with porous concrete about 10 years ago.
