There are cost savings to be gained as well. Rather than spend $375,000/mile on major rehabilitation, you instead spend $10,000/mile on distress repair, have two micro-surfacing treatments spread out over a several-year period each at $50,000/mile, and many years down the line the surface would then need minor rehabilitation at $250,000/mile bringing …

Micro surfacing is a polymer-modified, cold-application paving process. It relies on specialized equipment to combine polymer-modified asphalt emulsion, mineral aggregate, water and additives, and uniformly spread this mixture over a properly prepared surface. The asphalt emulsion breaks onto the pavement surface.
