Aqueducts 1/4

• Early aqueducts were channels bored through rock.
  
• The death of the channel below ground was varied
  to maintain a very shallow drop (less than 1/200)

• vertical shafts were bored at intervals to
  provide ventilation and access.
• As time went on roman engineers became more
  daring in the in the construction of high arches
  to support the conduits across valleys and plains

Aqueducts 2/4

• some of the later aqueducts were as tall as 100
  feet above ground level.
• Closed pipes were occasionally used to cross
  valleys by the inverted syphon method the
  pressure forced the water down and up again on
  the other side to a level slightly lower than
  before.

• But this system was costly, as it required lead
  pipes (lead had to be imported) and it was
  difficult to make strong enough joints
• So archers were far more common

Aqueducts 3/4

• Except were closed pipes were used, the channel
  in which the water flowed was 3feet wide x 6 feet
  tall,

• to allow workers to walk its length - when the
  water supply had been cut off - for inspection
  and maintenance.

Aqueducts 4/4

• Were the Aqueduct went through impermeable rock
  it was not lined, but were the the rock was
  porous, and were the conduit ran on arches

• A layer of concrete was applied to form a
  waterproof lining
• every now and then there was a sedimentation
  tank, were the flow of water slowed down and
  impurities removed

Roads

• Every were in Rome there were roads all of witch
  were made of stone the closest example I cam
  think of is the cobble stone roads in old St.
  Charles MO. But with bigger stones and primitive
  concrete holding it together.

How Aqueducts and roads were made

• The were made In a lot of different ways for more
  info look back at the Aqueduct section and the
  road section
• roads were huge stones arranged in a row and
  sealed with concrete.
• Aqueducts were very complex for there time the
  calculations had to be exact other wise the water
  would never reach Rome.
