I have a cousin who's a PennDot Engineer. About 15-20 years ago, PA switched to a new "environmentally friendly" asphalt mixture, which, by the way, degrades far more rapidly and has nowhere near the freeze-thaw resistance of the traditional mixture.

I vaguely recall Dee Thompson yammerin about biodegradable assfault several decades ago.
It had something to do with potholes, a PAT bus and busted axels... or something like that.
Anyway, that never woulda happened back when they had the cobblestones and streetcars anat.
I think the "Burgh oughta bring em back... BOTH of 'em...
And maybe build some new inclines too. There used to be a bunch of them.

How environmentally friendly is the frequent replacement process coupled with backed-up and rerouted traffic pouring their idling fumes into the atmosphere? Methinks it has more to do with providing inflated union jobs.
