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.


What is the purpose of using metal bars or mesh in the construction of concrete roads?

Concrete, while strong under compressive forces is very weak under stretching forces. Metal bars or mesh, while strong under stretching forces is very weak under compressive forces. Thus they compliment and mutually reinforce each other: where one is weak the other is strong.To make sure they are both able to work their best, the metal bars or mesh are first stretched then the concrete is pored over them. When the concrete completes setting the metal bars or mesh are released and they now compress the concrete while the concrete keeps them stretched. This is called prestressed concreteand it is much stronger than ordinary concrete.


How to improve road construction in village of rewari?

Road construction in the village of Rewari can be improved by patching the pot holes, as well as reinforcing them with concrete and steel rebar. Since climate and dust storms play a role in the construction and maintenance of the roads, it would also be necessary to keep the roads clean of debris.
