Bitumen:
Bitumen can be found in a
natural state (Athabasca deposits), but most of the bitumen used in the world is
manufactured in refineries.
Bitumen is obtained by the refining of selected
crude oils.
Pure or modified, fluxed or emulsified, its
properties of adhesivity, cohesion, elasticity,
waterproofing and its rheological properties makes
it a perfect material for road construction,
roofing and
industrial applications...

Emulsion Grade Bitumen
Emulsions grade bitumen are dispersions of bitumen in water. Hot bitumen,
water and emulsifier are processed in a high speed colloid mill that
disperses the bitumen in the water in the form of small droplets.. |

Industrial Grade Bitumen
Industrial grade bitumen or (Oxidized
Bitumen) are made by blowing air through hot paving
grade bitumen. The so-called blowing process results in
harder bitumen that softens at a higher temperature than
that at which paving grade bitumen softens... |
