Guy:
Technically speaking, to pave is to place any type of improved surface on a roadway, not just asphalt, so the reporter used the correct term. In addition, the state constructed the highway (yes, originally Route S-40) using concrete, of which cement is a major component. Concrete is a mixture of cement, sand, stone, and water; the sand and stone serve as both binding agents and filler to reduce the amount of cement needed to produce the mix.

Take it one step farther, Asphalt paving is often called bitiminous concrete...
