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.
Concrete was also used to assist the construction of the stone-paved roads, which were a Roman invention. A ditch was ploughed down to the firmest layer of ground that was found. The ditch was filled with rubble from local materials or sand (when it could be found) up to one metre from the surface level. A flat floor of compacted gravel was made. Then a surface was made by embedding the stones in concrete to create the paving. The concrete was laid in two thin layers. The bottom one had coarse concrete and the top one had fine concrete.
There is actually a very long list of the achievements you are asking , here are a few. The pantheon with its dome, the Colosseum with all its innovations, the extensive use of the arch, the aqueducts in Spain and Italy and the Pont du Gard in France.

Because when people would die people would be buried in these things called pyramids.
Some of the lasting contributions of ancient Egyptian civilization cover areas such as mathematics, engineering and medicine.

The use of the arch and the dome were both used in architectural and engineering projects, such as innovative buildings and bridges and above ground aqueducts.
Egypt has the pyramids and the sphinx as engineering achievements.
The use of the arch has to rank as one of the great achievements of Roman architecture and engineering, as they used the arch in their aqueducts and bridges in addition to other buildings. Their greatest achievement, in both these disciplines is the pantheon with its dome and oculus.
Ancient Romans were the first people to built the actual road system.
Some of the most important pyramids in the world include the Great Pyramid of Giza in Egypt, which is one of the Seven Wonders of the Ancient World, and the Pyramid of the Sun in Mexico, one of the largest pyramids in Mesoamerica. These pyramids are significant for their historical and cultural significance, as well as their architectural and engineering achievements.
