That's pretty cool, but "self healing" is a bit misleading.
It's not very self healing when it requires somebody to drive along with a vehicle that would heat up the road to fix it. That's like saying all current roads are self-healing because they just require someone to drive along and fill in the holes.
Still cool though, easier to repair roads are always good.
- hakaaaaak 14y agoMaybe they should call it a "more durable road".
- Cthulhu_ 14y agoIt's not more durable, it's easier to patch up. Simply said, this technique allows maintenance workers to heat the bitumen up uniformly, allowing it to flow and fix its own small cracks and brittleness, and avoiding larger damages over time.
- Retric 14y agoBumping that durability up from 8 to 16 years even with some maintenance is probably a net win, but it seems a long way from the 40+ years you can get from concrete.
