Badass article, super cool to think about filling pot holes with molten iron. Visited Pompeii with family when younger and one of the few things I remember “experiencing” were the wheel ruts while walking around. Very much makes sense now how difficult it’d be to fill in given the depth and width of the ruts; they’re expansive. Am not familiar with iron making but curious about iron slag. Welding slag is pretty light but if iron slag was used for ballast it must be substantial
