Introduction to Bituminous materials

The term bituminous materials is generally used to denote substances in which bitumen is present or from which it can be derived. Bitumen is defined as an amorphous, black or dark-colored, (solid, semi-solid, or viscous) cementitious substance, composed principally of high molecular weight hydrocarbons, and soluble in carbon disulfide.

For civil engineering applications, bituminous materials include primarily aphalts and tars. Asphalts may occur in nature (natural asphalts) or may be obtained from petroleum processing (petroleum asphalts). Tars do not occur in nature and are obtained as conden-sates in the processing of coal, petroleum, oil-shale, wood or other organic materials. Pitch is formed when a tar is partially distilled so that the volatile constituents have evaporated off from it. Bituminous mixtures are generally used to denote the combinations of bituminous materials (as binders), aggregates and additives.

This article presents the basic principles and practices of the usage of bituminous materials and mixtures in pavement construction. In recent years, the use of tars in highway construction has been very limited due to the concern with the possible emission of hazardous flumes when tars are heated.

Applications of Bitumen in scientific and engineering processes

Uses of Bitumen in Civil Engineering

Prefabricated Drains in the last few years, prefabricated geocomposite drainage materials have become available as a substitute for conventional drains with and without geotextiles. Geocomposites are probably most practical for lateral drainage situations geocomposites is the use of prefabricated vertical (“wick”) drains to accelerate the consolidation of soft compressible cohesive soil layers. Because they are much less expensive to install, geocomposite drains have made conventional sand drains obsolete.

Following is the list of applications of bitumen in real life:

  1. Bitumen Road Testing

    Hydraulics & erosion control Catchment areas, basins

  2. Dam groutings

  3. Dam linings, protection

  4. Dyke protection

  5. Ditch linings

  6. Drainage gutters, structures

  7. Embankment protection

  8. Groynes

  9. Jetties

  10. Levee protection

  11. Mattresses for levee & bank protection

  12. Membrane linings, waterproofing

  13. Reservoir linings

  14. Revetments

  15. Sand dune stabilisation

  16. Sewage lagoons, oxidation ponds

  17. Swimming pools

  18. Waste ponds

  19. Water barriers

  20. Backed felts
