Nerd out time, shits amazing

That's badass but the only potential problem I see if the freezing thing. Even places like South Florida freeze occasionally. Could a single freeze destroy 10's of millions of dollars of roadwork?

Yes

Oh I totally agree, but that shouldnt halt R&D on potential new alternatives. Tarmac said this:

"Also its ability to absorb water can be compromised by dirt and other particulate waste, such as sawdust or silt. Damage from freezing water is a potential concern with permeable pavement, although Lafarge Tarmac says its product has “excellent freeze-thaw resistance.”"

I work in the concrete industry and by nature, having air/pockets of air (5-8% content) is what allows us in canada to pour concrete outdoors that survives -30 weather. Just by having that small amount of air gives the concrete enough room to expand and contract without breaking apart.

so by nature their product is good to go. We are all assuming worst case scenario and yes, nothing holds up to worst case scenarios.
