RE: rebars in concrete road
As for your specific question: we use rebar in concrete pavement when we deem it necessary for reasons of either strength, serviceability, or durability. I know, that sounds trite. See link for more -- much more -- detail.
The greatest trick that bond stress ever pulled was convincing the world it didn't exist.

The most common reinforced concrete paving is CRCP, continuously reinforced concrete pavement. In CRCP, the reinforcement provides both positive and negative flexural reinforcement, and the relatively high reinforcement ratio keeps the cracks tight and the aggregates engaged. It will crack every 3-7 feet and act as a flexible pavement. As with all pavements, it works best on a well-prepared subgrade.
