    Modern road isn’t just asphalt and rock, there are layers of different rock and dirt packed down to provide a solid structure for it to sit on. Asphalt doesn’t have bend strength, it’s really just holding everything together.

    I went and saw the remains of George Washingtons house and it was buried like 10-15 feet underground. All the signs were talking about wars and stuff but not where the tons and tons of dirt came from.

    The medieval road looks like concrete, but I would have expected it to be just a mud track.

      I think a mud track with occasional bits of gravel is basically what the display is suggesting, it’s just that the mud is dry.
