The Romans built stone-paved roads which were covered with local rocks cut into squares or polygonal slabs of lava. These roads had a military purpose. They made the movement of soldiers and the delivery of supplies to troops at the front or stationed in garrisons much easier and faster. Their military nature was also shown in by the fact that they were usually built on a straight line, even when they crossed hilly areas. Traders also used these roads to transport their goods. They complained that the straight tracts over steep gradients made it very difficult for their laden wagons. After these complaints at least some of these tracts were redesigned to allow for less steep gradients.
The paved roads covered 20% (80,500 kilometres, 50,313 miles) of the total network of roads (400,000 kilometres, 250,000 miles) in the Roman Empire.
The difference between the four roads are; the expressway is designed to carry huge amounts of traffic quickly over long distances. Arterial roads carry moderate amounts of traffic over shorter distances. Collector roads move traffic from local roads to areterial roads. Local roads that are smaller and narrower than arterial roads.
No one knows the long lasting effects of GMOs, though some say people have been eating them since 1996 and that is evidence that there are no long lasting negative effects of GMOs. Since long term studies on rats that showed serious effects of GMO consumption have been discredited, and GMO foods are not labeled, it is hard to determine what the long lasting effects of GMOs are. There is evidence, though it is not accepted as valid by some, that people who are put on a non GMO diet have improved health.
Greeks and Romans came up with it, I believe. A long, long time ago.
Sturdy, cheap, good insulation, long lasting.
as long as you need and decision making
They trad long roads and receive blisters.
Modern architecture such as arches and other modern marvels aid todays engineers in creating masterpieces. Also, Romans were famous for creating their roads, which were long lasting and well made. We model our roads in the same design. Hope this helps?
No, the ancient Romans did not build the first road system, but they built the best. There were many good roads in the area that today we call the Middle East, but the ancient Persian empire is generally credited with having the first road system. In fact the practical Romans borrowed an aspect from the Persian system which was the placing of milestones and having rest stations at certain points.

The Romans improved this Bridges technology by engineering, architecture, & literature. Engineering included aqueducts and roads. Architecture helped with columns, archways, and domes on building.
they invented so many stuff, for example, roads, the letter G, a concrete which lasts a incredibly long time and they invented the forced pump. How much i love you romans!!
The Romans built stone paved roads, but this improvement in transport was probably used before, soon after wheeled transport became common. The Inca of South America were another peoples who used stone paved roads. And also extensive stone paved footpaths over long distances and undulating terrain.
The Romans build straight long roads made out of rocks. hat simple sentence is enough to explain Rome's fast expansion. Those roads allowed for easier and quicker transportation of troops and whatever else the army could need/want. They were able to move fast across the country to prevent any foreign intrusion. Without the roads, the Roman Empire would have been nothing than a single sand in the beach.
The term is hyphenated as "long-lasting" (persistent, perennial, long-lived).
