How did the Romans build their roads?

Answer 1

The Romans put layers on top of layers to build their roads... and they even had sidewalks!! The layers go like this:

1.Sand and dirt which was piled on the ground once the builders checked that the ground was level.

2.Crushed rock was layered on top of the sand.

3.Gravel in cement mortar was placed on top of that.

4.Cemented sand and gravel.

5.Large stone slabs that fit together so well, you can barely see cracks.

On the side, there was a drainage ditch, and a sidewalk. The builders were either slaves, or plebeians (low or middle class people).

Answer

They used layers of soil, rock and cobblestone. The width was the same as a chariot. You can see examples of Roman roads that exist to this day in Italy and England.

Answer 2

The Romans effected what historians call the Roman architectural revolution or concrete revolution. This involved the extensive use of concrete, the barrel (simple) arch and the vaulted arch. These three elements enabled the Romans to go beyond Greek methods of construction which used cut-stone and post-and-beam or post-and-lintel structures.

The Romans developed a type of concrete (opus caementicium) which was as resistant as modern concrete and also set underwater (and therefore could also be used to build docks for ports, dams, aqueducts and bridges). It was less fluid than modern concrete and had to be layered by hand. It was made by mixing a volcanic rock called pozzolana (which is named after Pozzuoli, a suburb of Naples) with lime as a binder and the addition of rubble from stones, bricks or pottery shreds as aggregates which added body to it. Concrete had technical and practical advantages. It was exceptionally strong and could span great distances when shaped into arches, vaults and domes as it could be moulded. It was layered into a formwork and it took the shape of its container. It did not require skilled labour and therefore was cheaper. It was much faster for construction than laborious masonry walls. It was safer because concrete vaulted roofing was fireproof, unlike the wooden-beamed roofs of traditional construction post-and-lintel methods.

The potential of the previously little used arch, vault, and dome was fully exploited for the first time. The Romans were the first to fully appreciate the advantage of these structures.The arch has a strong load- bearing capacity. The vault has an even greater load-bearing capacity and its structure is suited to support large roofs. Their construction in concrete made them easier to build and even stronger. This led to the use larger and monumental arches and vaults on a grand scale. However, the Romans did not abandon masonry arches and vaults. The vaulted arch came into two forms: the groin arch was formed with two to four intersecting barrel (simple) arches and the rib arch, where the intersecting barrels were not of the same diameter.

Answer 3

The Romans used some kind of ingredients to make their own special concrete that they used to build with.

Answer 4

How did the Romans build their house they got loads of people to stand in a line.
