Too bad this would be useless here in Brazil, in fact MORE useless... Here I've seen many times asphalt with objects embedded on it (usually bottle caps), because many places in Brazil get hot enough to asphalt partially melt, this technology here would be REALLY self-healing. The problem is, asphalt that is very cheap to fix, and more durable, or cheaper in long term, is not interesting, because it means less money to steal, in Brazil everyone knows that the purpose of roads is steal public money, not to use, this is why every road or is full of holes, or full of patches.
