They actually weren't stones, but cobblestones. Cobblestones are shaped stone in squares and put together in a set pattern and measured . The road was leveled and the stones set in sand.
So water does not pool on the road surface.

The Romans did not "invent" roads. Roads wee around hundreds of years before Rome existed. What they did do is greatly improve them and build many more roads than had previously existed.
Approximately 2% of the total surface area of Britain is covered by roads.
The first indications of constructed roads date from about 4000 BC and consist of stone paved streets at Ur in modern-day Iraq and timber roads preserved in a swamp in Glastonbury, England.
The Roman engineers created roads that went through natural obstacles rather than around them wherever possible. A Roman road consisted of two parallel trenches and a well drained core. Packed small stones were the foundation and the drainage system was the best the ancient world had ever seen. Layers of concrete and cement and concrete gravel made the roads durable. The top layer was made of gravel, packed stones and paving stones.
The idea of milestones is an old one. When the ancient Romans built roads across Europe, they placed special stones at the sides of the roadways at regular intervals. Travelers could use these stones as identifiers to mark their progress.

Roman roads were made with interlocking stones or pavers and still exist. They were well made. Modern are made with a tar base and eventually break down.
