BITUMEN DEMAND GROWTH
  • Bitumen demand is likely to grow at 12 per year
    for next five years
  • At this rate the demand in year 2004-05 would be
    3900 TMT

BITUMEN SEASONALITY
14
Bitumen - An introduction
  • LAST RESIDUE OF CRUDE OIL TREATED TO PRODUCE
    BITUMEN.
  • USED IN BUILDING AND PAVING SINCE ANCIENT TIMES.
  • OLDEST ADHESIVE KNOWN TO MAN.
  • USED IN 3500 B.C. AS MORTAR FOR BUILDING STONES
    AND PAVING BLOCKS IN MESOPOTAMIA.
  • USED FOR WATER TIGHTENING OF RESERVOIRS, CANALS,
    BATHING POOLS EMBANKMENTS OF RIVERS IN INDUS
    VALLEY.

15
Bitumen - An introduction (Contd.)
  • Streets of Babylon constructed in 2000 B.C. still
    in good shape.
  • Used for Mummification in 300 B.C.
  • Rock Asphalt used for flooring/sidewalks in
    France in 1800 A.D.
  • First road surfacing done in New Jersey in 1870
    A.D.
  • From 1900 onwards Bitumen produced from
    Refineries being used extensively.

16
Types of Bitumen
  • Conventional Bitumen
  • Paving Grade Bitumen
  • Industrial Grade Bitumen
  • Bitumen Emulsions
  • Modified Bitumen

17
Production Process
  • Produced by fractional distillation of Crude oil.
  • Crude Oil heated to 300 350OC in distillation
    column. Lighter fractions separated at different
    column heights. Bottom product called long
    residue.
  • Long residue heated upto 450OC in Vacuum
    distillation column. Bottom residue (short
    residue) used for manufacturing Bitumen.
  • Hot air is blown through short residue OR
    blended with superior quality bottom products to
    achieve desired consistency / penetration.

18
Advantages of Bituminous Roads
  • Initial saving fast construction low cost.
  • Ageless rehabilitation is inexpensive.
  • Stage Construction - in ribbons, not in slabs.
  • Safe High skid resistance Good Visibility
  • Better riding quality Less wear tear of
    vehicle, Low noise while cruising
  • Can be fully recycled.

19
Engineering Properties of Bitumen
  • A visco-elastic material Deformation under
    stress a function of temperature loading time.
  • At high temperature loading it behaves as
    viscous liquids, whereas at very low temperature
    or low loading it behaves as elastic solids.
  • In the intermediate range of temperatures /
    pressure, more typical of the conditions in road
    service, bitumen has visco-elastic behaviour.

20
Elemental Analysis
  • Carbon 82 - 88
  • Hydrogen 8 - 11
  • Sulphur 0 - 6
  • Oxygen 0 - 1.5
  • Nitrogen 0 - 1

21
Composition of Bitumen
  • Chemical composition depends on origin of Crude
    Oil and refining process.
  • Chemical composition is extremely complex.
    Astronomically large number of Molecules with
    different chemical structures. Not feasible to
    attempt a complete analysis of Bitumen.
  • Elemental composition of Bitumen provides little
    information of the types of molecular structure
    present in Bitumen.

30
Selection of Grade of Bitumen
  • Choice of Bitumen is based on
  • Climatic Conditions - Maximum Minimum
    temperature rainfall.
  • Intensity of Traffic - Number of vehicles per
    day axle load of vehicles.

31
Applications of 80/100 Grade
  • Less viscous grade.
  • Used in all climatic conditions.
  • Suited for traffic load of less that 1500
    commercial vehicles/day.
  • Better suited for high altitude/snow bound
    regions irrespective of traffic intensity.

32
Applications of 60/70 Grade
  • More viscous grade. Higher softening point.
  • Suited for traffic intensity of more than 1500
    commercial vehicles/ day.
  • Can withstand heavier axle loads.
  • Suited for areas where difference between min.
    max. temp. is more than 25 o C.
  • Reduced stripping of Bitumen from Aggregate in
    presence of water.
  • Better suited for highways, expressways
    urban roads.

33
Applications of 30/40 Grade
  • Suited for traffic intensity of more than 1500
    commercial vehicles/ day.
  • Suited for areas where difference between min.
    max. temp. is less than 25 o C.

CRUMB RUBBER MODIFIED BITUMEN
41
Crumb Rubber Modified Bitumen
  • Bitumen
  • Additives (Modifiers/Treated Crumb Rubber)

42
What is Crumb Rubber Modified Bitumen?
  • Crumb Rubber Modified Bitumen is Conventional
    Bitumen with treated Crumb Rubber Additive at
    high temperature which results in
  • Lower susceptibility to temp. variation
  • Higher resistance to deformation at high
    temperature
  • Better Age Resistance Properties
  • Higher Fatigue Life of Mixes
  • Better Adhesion Properties

43
Why Treat Crumb Rubber?
  • Be compatible with Bitumen.
  • Blend with Bitumen properly thoroughly.
  • Improve temperature resistance of Bitumen.
  • Resist degradation of Bituminous mix.
  • Be capable of being processed by conventional
    mixing plants and laying machinery.
  • Produce coating viscosity at application temp.
  • Maintain premium properties during
    storage,application and in service.
  • Be cost-effective considering life cycle cost.

44
Test and Trials with CRMB
  • Central Road Research Institute, New Delhi.
  • Highway Research Station, Chennai.
  • Gujarat Engineering Research Institute, Vadodara.
  • Indian Institute of Technology, Kharagpur.
  • Municipal Corporation of Delhi.
  • Research Station, P.W (RB) Dept., Hyderabad.,
    Andhra Pradesh.

45
Circular Test track study conducted by Highway
Research Station, Chennai
46
Tests conducted in Circular Test Track Study
  • Surface Evaluation
  • Skid resistance
  • Texture depth
  • Depletion values

47
STUDY RESULT
  • CRMB mixes indicate better resistance to
    deformation at high temperature - 1.5 times
    higher values of stability, Marshall quotient and
    stiffness modulus.
  • Higher indirect tensile strength and stiffness
    modulus - better resistance to cracking in
    structural layers.
  • Modified mixes in structural layers take higher
    traffic stresses due to higher values of
    stiffness modulus.
  • Tensile strength ratio before and after
    conditioning in water is higher - superior
    resistance to moisture damage.

48
CIRCULAR TEST TRACK STUDY CONCLUSION
  • The Highways Research Station has opined that
    the performance of modified bitumen stretch
    improves by 1.7 times than the conventional
    bitumen stretch.

49
