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. They became essential for large roofs and large buildings, such as basilicas (public buildings) amphitheatres (arenas), theatres, baths, domes, forts and fortifications and dams. They also made it possible to build bridges which were much longer than before and could cross much wider rivers and valleys.
Prior to the Romans concrete was hardly used. The Romans were the first to made large scale use of it. They developed a type of concrete (opus caementicium) which was as resistant as modern concrete. It also set underwater and therefore could be used to build docks for ports, dams 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. The two acted as a binder and rubble from stones, bricks or pottery shreds were added as aggregates which added body to it. Concrete had technical and practical advantages. It was exceptionally strong. it could be moulded and could span great distances when shaped into arches, vaults and domes. 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 post-and-lintel construction methods.
The potential of the previously very little used arch and vault, were fully exploited for the first time. The Romans were the first to fully appreciate the advantage of these structures and make large scale use of them. The Etruscans are thought to have invented the simple (barrel) arch. The oldest example of the vaulted arch has been found in the Greek city of Pergamon (in western Turkey). The (simple, barrel) arch has a strong load- bearing capacity and was useful to build large walls without using the post-and-lintel method and to build bridges which were much longer than ever before. The vault (vaulted arch) 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 is formed by two to four intersecting barrel (simple) arches and the rib arch, where the intersecting arches were of different diameter.

How long does it take to build a roman arutecture?
It depends on what king of building and its size and the type of material used. The Romans had many different type of buildings and they came in many different sizes. They also built in stone, bricks of (roman) concrete. Stone buildings took longer to construct.
Who did the Romans hire to increase the size of their armies?
The Romans made use of auxiliaries to both increase the size of their armies and to provide specialized military skills that the Romans needed. For example, the Batavians were great swimmers and horsemen so the Romans incorporated them into their army especially in areas where there were unbridged rivers as in the area of Germany. The Batavians would swim (with their armor and horses) across the river, give any enemy they encountered a hard time, and give the Roman infantry time to build a bridge. Archers and slingers were used in circumstances where they were needed. Most of the auxiliaries were levied from client kings or provinces and upon discharge from the army usually received Roman citizenship.The Romans made use of auxiliaries to both increase the size of their armies and to provide specialized military skills that the Romans needed.
