6. • Asphalt materials have been utilized since 3500 B.C. IN
building and road construction.
• Demand for paving roads in late 1800 lead to use of
petroleum asphalts .
• These early asphalts were native asphalt .
• which were found in pools and asphalt lake .

7. Asphalt is simply the residue left over from petroleum
refining .
1-Crude oil is heated in a large furnace to about 340 C
partially vaporized .
2-it is then fed into distillation tower where the lighter
components vaporize and drawn off For future processing
3-The residue from this process (Asphalt) is usually fed into
a vacuum distillation unit where heavier gas oils are drawn
off.
