Some good and not-so-good leaders in the past created a lot of these street or roads for the advancement of their commerce (or trade) or to facilitate conquering or dominating other societies. These main roads started as just flat, passable (either rocky or muddied) path to hard and very durable concrete or asphalt.

The Middle East of the old times harnessed these naturally occurring substances to create or make cement carvings. Other than these artistic expressions, asphalt was also used for waterproofing and ship caulking as well. In early Europe, these asphalt stuffs were used for lining of cisterns, creating or building flat roofs and for constructing pavements.
