Explanation:
If the road was poured in one piece it would have cracks all over the place. Instead it is poured in smaller sections with small gaps in between that allow the concrete to expand and contract due to heat changes. The strip on top is a seal to stop water from getting into the crack and also to create a smooth finish.
