Created with Fabric.js 1.4.5 Roman technologys "All roads lead to rome." "I came, I saw, I conquered." Why do you speak to me of the stones? It is only the arch that matters to me. Roman roads were one of the backbones of the Roman empires projection of power over a vast expanse of territory, in its time it was the up until then most sophiscated network of roads that humanitity as ever seen. Without a sophisticated network of roads the Roman empire would not have been able to conquer as much land as they did. This is because they would not be able to transport the population around as effectively. At its peak there were more than 80,000 kilometers of roads in the Roman empire. One key innovation that contributed to the success of the Roman road design was a materiel never used before: Roman concrete. Roman concrete contained only 4 ingredients: Limestone, sand, water and volcano ashes. When we combine these ingredients to a certain method it makes a really hard materiel useful for building and making roads, it also has many other positive attributes such as resistance to frost, sunlight etc. Romans built their roads by using multiple materials, using multiple layers for strength. You can see a diagram of this below.Roman roads are very similar to the roads that we use today as they both are highest in the middle then slope down to let rain water drain out and they both use compacted sand for a foundation. Roman archesThe exact origin of arches is unknown some say that it was an Etrucian invention, but others say that it was invented in sicily. The only thing we know for sure is that it was first used widely in the Roman empire.Roman arches played a big part in Roman architecture. The construction of multiple big buildings in the Roman Empire such as the Coloseum would not have been possible with out arches. Arches enabled the Roman empire to build large buildings such as temples and aquaducts. Arches are used widely in modern society, mostly in bridges. Todays arches may differ slighty to Roman arches, but they all use the same concept The ballista was first invented by the Greek and then gradually improved on and used by the Romans. The ballista was one of the main weapons behind the success of the Roman army. The ballista was originally a fixed-position weapon and not very practical. It could fire stones and bolts ranging from 5 kg to 25 kg in weight. It was used as a long-range weapon and is said that it was a very fearful sight for the opposing side. The Romans also had a smaller version called the Scorpio, which was a one-man operated weapon and a lot more practical. The modern day equivalent of the Ballista is the crossbow, which is a lot smaller, but still uses the same concept as the Roman ballista.
