What is concrete pavement?
Concrete pavement is a type of pavement made from a mixture of cement, water, and aggregates such as sand and gravel. It is used in roads, sidewalks, driveways, and other outdoor surfaces due to its durability, strength, and long lifespan. Concrete pavement provides a smooth and stable surface for vehicles and pedestrians.

What did the romans use to build roads?
They used pounded earth. also... : They were the first ones after the Assyrians to use concrete. They had layer upon layers. Started with earth, then dirt, then limestone, and then concrete and closely put together pavement stones to make the ground/road level.
Why is it that concrete roads are laid in sections with pitch between them?
Concrete roads are laid in sections with joints or pitch to accommodate the natural expansion and contraction of the material due to temperature changes. These joints prevent cracking and structural damage by allowing the concrete to move without restraint. Additionally, the sections facilitate maintenance and repair, as damaged segments can be replaced without affecting the entire road. This design enhances the longevity and durability of the pavement.
What is a good test of the quality of roman road construction?
A good test of the quality of Roman road construction is how well their roads are preserved after so many centuries. Many sections of the stone-paved roads are still pretty much how they were in their original condition. The quality of construction of the two other types of Roman roads, gravel roads and earthen roads, was not as good. We also know that the construction quality of stone-paved roads was very high because we have descriptions. To build a via munita (stone-paved road) a ditch was ploughed down to the firmest layer of ground that was found. The ditch was filled with rubble from local materials or sand (when it could be found) up to one metre from the surface level. A flat floor of compressed gravel was then made. Then a surface was made by embedding the stones in concrete to create the paving. The concrete was laid in two thin layers. The bottom one had coarse concrete and the top one had fine concrete.
Are there concrete roads in Washington state?

What kind of damage does category 5 tornadoes do?
An F5 tornado causes total devastation. Well built houses disintegrate and are blown clean off their foundations, trees are stripped of their bark, pavement is peeled from roads, structures of reinforced concrete collapse.
