Paving tiles are so much easier to repair, pull & replace for utility work & #tree root care, and rearrange for new road layouts than #asphalt or #concrete.

Tiles are cheaper, can embed rather than spew #carbon, and provide drainage.

Photo next to #transit hub in #Lund #Sweden. White crosswalk pavers in arc of gray pavers. Smooth enough for #disability & #bike use. Perfect for #transit speed.

And pavers can hold the weight of a #bus.

#PavingTiles for the win!

I very much doubt that tiles are cheaper than asphalt. They're horrible for biking and snow removal is more difficult.

@indri @CathyTuttle ashphalt is basically oil. It has slag, a waste material from steel making as the pebbles. I think there are better options. Using stone made the Appian Way last 2000 years.

The only fossil fuel based material I like for roads is recycled plastic to get rid of it as that is a very long-lasting material - far better than using new oil.

We have to end the use of fossil fuels and different roading is part of that

Finding different materials instead of asphalt is a different discussion, but this kind of tiles isn't the solution either. It's awful to drive over with any vehicle, can get slippery when wet, and its very noisy. And the high quality granite has to come from somewhere too.

@indri @CathyTuttle But just "having to come from somewhere, too" is not the problem with asphalt roads.

Continuing to use oil as roading surfaces perpetuates the use of fossil fuels, endangering our climate.

And stone lasts 2,000 years or more. (The Appian Way) So it is very sustainable despite coming from somewhere. At least it remains pretty much forever somewhere else.
