New asphalt that contains its own de-icer!

Very clever, doesn't sound like it would add significantly to the cost per mile of road as it's an additive, not a replacement for something important.

They reformulated salt so it's not sodium chloride, combined it with some other stuff, then micro-encapsulated it. Mixed it with the top asphalt layer and laid it down on a freeway offramp. And it stayed ice-free! Every time someone drives across it, it ruptures some of the micro-encapsulated stuff and it releases, constantly fighting the ice. It's estimated that it could last five to seven years.

Yeah, no info on price, I imagine it's still a research project and not yet a commercial product.

I think the heated ones around the main clinic building have been there for ages.

I need to win the lottery and put some in at home. LOL........
