> Yes, the microtrench became a disaster, because the material they used to cover the drench stuck to people's tires when it was hot outside and it pulled up. Paving over it would have solved the problem
Paving it over would mean digging the trench deeper, meaning it's no longer a "nanotrench" (Google's experiment) but a "microtrench" (a very popular method of fiber deployment). These are trenches that are cut down below the road surface (12-24 inches), filled in, and paved/sealed on top to match the road surface. For this you need conduit, filler material, asphalt sealant, and a bit more labor.
